Baptism by Fire for online Dynamics and Modeling

Dynamics and modeling training with a green screen
Adrian Rankers and Hans Vermeulen had a sudden challenge when ASML Wilton insisted on providing the planned four-day Dynamics and Modeling training online. Rankers started working with green screen, Open Broadcaster Software, a camcorder, and document camera and after taking countless bumps and hard lessons learned, the training was successfully completed a month later.

In this article, Rankers of Mechatronics Academy and co-trainer Vermeulen share their experience on how to roll out a highly practice-oriented training course full of exercises online. They talk about the considerations, choices and tricky bumps, as well as about their experience with an ultimately very successful session of Dynamics and Modeling. They didn’t hold back their comments either.

Dynamics and Modeling revolves around the many aspects that influence the performance of mechatronic precision systems. In order to get that knowledge into your head, participants in the training should mainly work with exercises. One way this is achieved is by giving putting participants to work using the design tool 20-sim. “They do this in groups of two or three, with us looking over their shoulders,” says Hans Vermeulen, senior principal architect of EUV Optics System at ASML and part-time professor at TU Eindhoven. This need for intensive interaction between participants and trainers is a big reason why the training was never offered online before.

Last May, Dynamics and Modeling was scheduled for twenty ASML employees in Wilton, Connecticut. But when the first measures against corona came into force, travelling to the US was no longer possible for Rankers and Vermeulen. To guarantee the quality, they proposed to postpone the training until the autumn. However, the machine builder insisted: the technical experts in Wilton really felt the need to obtain the knowledge. That’s when the duo decided to wring the four-day course into an online format.

Better connection between ppt-slide and speaker

Coincidentally, Rankers had recently taken part in a conference that the American Society for Precision Engineering was forced to hold in Zoom. He was pleased with the design and quality. However, his trainer-senses also noted a disadvantage. “It was very tiring for me to look at a powerpoint with a moving mouse and a presenter that was only visible in a small window,” he says.

Reflecting on the upcoming course, Rankers realized that it is much more fun to watch a video stream where the teacher is visible from the waist up next to the presentation. “This creates a better relationship between the slide and the speaker explaining the information.”

Rankers looked around and saw three options to achieve this. It is possible to project a powerpoint on a wall and video stream the teacher plus projection with a camera. You can do the same with a large TV screen.

The third option was to put the instructor in front of a well-lit green screen, cut him loose using software and then mount him in the powerpoint presentation and share that stream via Zoom or Teams. Just like the weatherman on the NOS news, the trainer has to coordinate his instructions via his own screen.

Experimenting with green screen and OBS

Rankers decided to experiment with green screen and Open Broadcaster Software (OBS). He borrowed a large green tablecloth from a friend and hung it over a telescopic handle for garden tools. Photo shops already sell good green screen cloths for 30 euro. But because they were all sold out, instead it became a 4 by 6 meter cloth for 80 euros – also reasonably affordable.

Green screen & Open Broadcaster Software
Through this screen Adrian Rankers coordinated his movements with the information on the powerpoint slides.

His first experiment with the tablecloth already worked “surprisingly well.” Rankers noticed that it was the exposure that counted. “If you go for Hollywood quality, seeing every hair of the presenter, it comes close. My wood and rope setup worked surprisingly well in sufficient daylight, especially when you consider that a lot of detail is lost in video streaming to the other side of the world anyway.” As a backup, he checked the available large-screen TVs in a nearby shop.

Because of the time difference, the training for ASML Wilton required afternoon and evening sessions, so Rankers also wanted to test the lighting conditions in the evening. “I figured this might be an issue,” he says. “From the information on the internet I concluded that evening shots were really different. Without good artificial light, the software doesn’t properly cut the person out of the green background.”

The nocturnal farewell drink at a distance at the end of an ASPE conference at MIT gave Rankers the opportunity to briefly test and experiment with it. Surprisingly, it turned out to work with the available artificial light in the space that Mechatronics Academy and High Tech Institute had set up at the Fellenoord location in Eindhoven. “I’ve had a lot of positive reactions and agreed with MIT pro Dave Trumper that I would share our first course experiences with him.”

Whiteboard and document camera

During their physical training Rankers and Vermeulen write a lot on a flipchart or whiteboard. Teams (which was chosen at the request of ASML) offers the possibility to write with the mouse, but that gave problems. In trials Rankers conducted in preparation with ASML Wilton, it was reported that participants could not use their whiteboard function. They also couldn’t share their own screen. The whiteboard problem was confirmed by Microsoft and appeared to be related to (GDPR) privacy rules.

That’s why Rankers on the trainer-side immediately sought refuge with a document camera. “A document camera is similar to a webcam on a tripod, which is aimed at a sheet of A4,” explains Rankers. “This can be easily autofocused on the paper at the touch of a button and then hold this setting. If you’re going to write, that’s fine. It’s not going to be disturbed by, say, autofocus on your hand.”

Dynamics Modeling
Both the trainer and his co-trainer have a screen on which you can see the image that is also presented to the participants.

Rankers and Vermeulen were both very satisfied with the document camera. “But switching between them is one of the minuses,” says Vermeulen. “In a physical training course, participants see everything side by side: powerpoint, whiteboard and trainer. Now they only saw our pen on the paper. If we switched to presentation, they’d have lost that image again.”

Rankers adds that entering an additional camera signal “still requires some dexterity” because of the switching between applications, presentations and the document camera. “That’s a bit more complicated because of the combi green screen and OBS,” he thinks. Especially switching to an application like 20-sim takes some practice. Operating the computer tool via a monitor a few meters away from you was not easy. As a double check, Rankers invited himself via private email so that he could see on his mobile phone at all times what the students had in view.

Data rate prioritized

A point of attention was the internet speed at High Tech Institute on location Fellenoord. This could be a potential bottleneck. The common throughput speed of all tenants together turned out to be only 100 Mb/s, while for a video stream 5 Mb/s is quickly needed. It turned out that the IT department wanted to give one IP address a higher priority for four days.

Rankers says, with a small sigh, that the people in Wilton, like his students at the TUE, only started installing 20-sim in the weekend before the training. “That didn’t go well because of the security of their ASML laptops,” says Rankers. The result was a lot of email communication just before the training and an escalation to the IT helpdesk to facilitate the final installations. “Next time, I’m really going to call everyone a week in advance and check on the preparation,” he laughs.

Rankers had made five short introductory videos for 20-sim and sent them in advance to teach the participants all the essentials of the tooling. In the future, he plans to add a video with the latest checks and send it well in advance. “So they know what we expect as basic knowledge.”

Interaction with the students

In the training setting Rankers and Vermeulen used a laptop with two external monitors. At an angle under the monitor with the constructed video image was also a second external monitor on which the Teams-meeting was shown.

In the training, in which everyone participated from home, most students unfortunately did not have a webcam. Rankers had also noticed that the connection would not work as well if everyone turned on their camera. That’s why they finally chose to only switch on the available webcams during the proposal round. “We didn’t see students, just the glowing balls with initials when questions were asked.”

'Online, you could easily log the participation in order to more specifically encourage some people to participate.'

Initially, Rankers asked the students to respond via the chat function and by raising their hands when they were in the picture. “Chat in itself worked well, but leaves little room for extensive discourse,” he says. “Hand-raising requires the presenter or his companion to be very alert, and that wasn’t always the case. In the end, after the first part of the day, we agreed that everyone would just interrupt and ask questions through their microphone. That worked well. There was a lot of interaction, but just like in an ordinary classroom, some stay quiet with a wait-and-see approach .” According to Rankers, there is still room for improvement. “Online, you could easily log the participation in order to more specifically encourage some people to participate.”

Practical exercises online

In the exercises, participants worked with teams that changed each day. Sometimes in pairs, sometimes in groups of four or five. In doing so, Rankers and invite Vermeulen to watch. Rankers: “There was good discussion within the groups, but there is still room for improvement in the guidance”. Vermeulen: “During an in-person training, you watch along and see immediately if the screen gets stuck. What we found is that online, participants didn’t speak up to let us know when it froze. It worked better with groups of four or five people than with couples,” describes Vermeulen. According to him, “Larger groups also work better online because there are always a number of people among them who are a bit more experienced and who pull the other along with them.”


Online training with a co-trainer on standby was a pleasant experience for Rankers and Vermeulen.

Rankers and Vermeulen alternated every hour and a half. In addition, they noticed that training is pleasant when someone is on standby. “Presenting the whole thing takes some getting used to. It’s really nice with two people.” Rankers also has training sessions in which he uses a different teacher every part of the day. “Then you actually always need someone to instruct and deal with calamities.”

The duo was largely spared the latter. During the four days, Rankers and Vermeulen had to do a hard restart only once, because the system got stuck. In the end, Rankers concluded that they had completed a successful edition, “with a lot of ideas to do it even better and perhaps simpler.”

Four afternoons and evenings of Dynamics and Modeling are intensive for Vermeulen. In the evening around 11 p.m. at home, preparing course in the morning while his children also asked for attention now and then. “It’s second best,” he says when asked to choose between an on-site training and saving a tiring journey. “Being there live is by far my preference,” he says. “Especially with all the exercises. I can imagine that you can give a very good training online. We do that in college. But a lot of interaction requires physical presence. I think for one or two days of training I would opt for online, for four or five days, I would choose to take the penalty of flying six hours there and six hours back. For Asia, online training is difficult because of the time difference, unless both teachers and students make concessions. At our upcoming online design principles training for ITRI in Taiwan, shortly after the summer holidays, we will start extra early in the morning on our side and the students will continue in their time zone in the evening until 22.00 hours”.

The evaluation of the first online training Dynamics and Modeling showed very satisfied participants. Apart from the remark whether this intensive training might not have been better given in five days, the students were full of praise afterwards. Below is a selection of the category ‘general remarks’ from the evaluations:

  • “Lecturers are very experienced and have vast knowledge on these topics. I find this training very useful and a nice summary on multiple topics. It is a pity that the training was online, I feel like in person training would benefit all and it would be even better than it was.”
  • “At times there were technological challenges. I do wonder if Zoom would have worked better.”
  • “Intensive content, but very good learning experience with down to earth explanation. Thanks.”
  • “The virtual setup was fairly successful, with very few disruptions. Overall a success!”
  • “Great training overall — excellent instructors & good use of physical ‘case studies’ to illustrate concepts”
  • “It would have been better if the training was given in 5-day time period instead of compressed 4-day period. There was a lot of good material. It would have helped to absorb that material better over 5-day period. It would also have given time to spend more time on the in-class exercises.”
  • “Very practical training with the correct mix of theory and fundamental content. Very well delivered by the presenter.”

Recommendation by former participants

By the end of the training participants are asked to fill out an evaluation form. To the question: 'Would you recommend this training to others?' they responded with a 8.9 out of 10.

“The mechatronics curricula are very meaningful and relevant”

Testimonial Vinicius Licks about the mechatronics trainings of High Tech Institute
The Netherlands has long worked to put its stamp on mechatronics design and development. One way the country maintains its ‘Dutch approach’ is through trainings to transfer the knowledge. But how does that differ from other regions in the world? Vinicius Licks, professor of mechatronics at Brazil’s Insper College, shares what he observed attending Dutch mechatronics training.

With a rich history of technical innovation embedded in its culture, the Netherlands has long been at the cutting edge of technology and engineering. This advanced position stems, in part, from the robust relationship between industry leaders and the technical universities. However, another instrument the Dutch use to maintain a healthy high-tech ecosystem is through the utilization of courses and trainings to both transfer and preserve the knowledge. Now, as the Netherlands’ high-tech industry continues to hold its influence on global markets and supply chains, it should come as no surprise that the country’s expertise and skills within the realm are also of great international appeal.

Just ask Vinicius Licks, professor and associate dean of the mechatronics program at Insper College in São Paulo, Brazil. In 2018, Licks made his first of three long treks from South America straight to the Netherlands. He didn’t travel across the globe to enjoy a vacation; he came to get a feel for the Dutch high-tech environment, specifically through the mechatronics training cluster provided by High Tech Institute. “Training is one of the best ways to get in touch with new ideas and often to get new perspectives on old ideas,” says Licks. “It’s a great opportunity to communicate with your peers, exchange best practices and learn how to push the state-of-the-art in the field.”

Eye opening

Of course, coming from a setting in higher education, Licks was more accustomed to attending conferences, rather than technical training programs. “I work for an academic institution, so usually we’re the trainers, not the trainees,” he jokes. “But this was truly an eye-opening experience for me.” According to Licks, his first course, the “Motion control tuning” training, offered him a vastly different perspective on teaching and learning feedback control. “Most schools that I’m familiar with emphasize system identification in the sense that you must use it first to get a plant model to work with in your tuning efforts. The approach that I was exposed to during the training, however, was more experimentalist. The focus was less on the ‘modeling from first principles’ part and more on using frequency response estimates to tune the controller iteratively. While this approach to teaching feedback control was new to me, it was clear that for the control engineers in the Dutch mechatronics cluster, this was common sense.”

''The courses really helped me sharpen my skills and understanding of the Dutch cultural approach to mechatronics.''

Enthusiastic after completing his first course, Licks made the long journey across the Atlantic twice more in 2019, specifically for two more courses in the Mechatronics Academy’s training curriculum: “Advanced motion control” and “Experimental techniques in mechatronics.” “I was so impressed with the courses that I attended, they really helped me sharpen my skills and understanding of the Dutch cultural approach to mechatronics, both practical and theoretical,” highlights Licks. “The instructors were very knowledgeable and all of them professionally connected due to working or studying together in the past. That makes a big difference in terms of continuity and coherence of the content they’re delivering – all with the same vocabulary and experimental references.”

“The curricula are very meaningful and relevant. They’re completely designed for someone who wants to have a complete view of the field of mechatronics design. The sequence of courses is built in such a way that some frameworks will be dealt with continuously, but from different perspectives and with increasing complexity. This is very rewarding because you feel that someone has put in time and effort to really think about what’s included in every one of the courses,” depicts Licks. “It’s most likely, of course, that this is the work of many people and the outcome of several iterations of offering the same courses along the years, but also of caring to ‘close the loop’ with student feedback.”

How were these trainings different from others that you’ve attended elsewhere?

“These trainings, in particular, have given me a different perspective about how feedback control theory can be taught and learned, as well as the importance of creating common project frameworks before sharing these frameworks with all your teams and making sure that every new team member will be well-versed in those frameworks as soon as possible. Coming from outside the Dutch cluster, it’s very interesting to realize how much shared knowledge there is in this industry in the Netherlands. People have been indoctrinated, in a positive way, into using the same conceptual tools and vocabularies, which makes the region much more productive. It’s amazing to see all these people getting so excited to look at an experimental Nyquist plot,” laughs Licks, “I’ve never seen such a fervent devotion to the frequency response function.”

Pragmatic

Another specific difference that Licks sees in the Dutch courses, versus others, is the style and format in which the training is presented. He says, of the several previous trainings he’s attended, they almost always fall in one of two categories: extremely theoretical or purely empirical. “Instructors coming from academia tend to be more prone to the theory, while typically, the industrial side is drawn the other way. What I experienced in the Netherlands was a methodology that mixed both worlds in such a way that theory was always informed by experimentation. You see that theory actually works in practice and you have a robust understanding of why this works because of the theoretical background. It’s this approach to teaching and learning that reflects much of the pragmatism embedded in the ‘Dutch way’ of doing mechatronics design.”

Do you have any plans to return for a fourth training course?

“As a matter of fact, yes. I’m looking forward to attending the ‘Advanced feedforward and learning control’ training. But I still have to convince the organizers to include additional sessions closer to the summer when the weather in the Netherlands is way more attractive!”

Industry meets research in practical mechatronics trainings

Interview with Adrian Rankers, trainer of mechatronics trainings
Translating academic insights in the field of mechatronics into industrial practice: that is the core of the training offered by Mechatronics Academy. Adrian Rankers, in addition to Jan van Eijk and Maarten Steinbuch co-founder of this training institute, knows what is going on in the field. He is committed to guaranteeing the best trainers, furthering the development of existing training courses and the setting up of new ones.

“The fact that I ended up in the coaching profession is actually quite logical in retrospect, because education has always attracted me,” says Adrian Rankers. “I gave tutoring as early as the age of fifteen. A few hours at first, but soon, that became more. I remember giving tutoring to the son of a top executive at Shell and quickly becoming his complete homework support. My attraction to the technical side certainly had something to do with my father. He had also studied mechanical engineering and worked, first in industry and later as a professor.”


“It is essential to realize that the students still have to go through the learning curve and that some things are quite difficult and might not be obvious to everyone. As a trainer you have to be aware of this and take the time to do so.”

After completing his mechanical engineering studies at Delft University of Technology, Rankers started his career at Philips at the Centre for Manufacturing Technology (CFT). Here he was involved in the dynamics and control techniques for CD players and wafer steppers. In the evening hours, he worked on his PhD research resulting from this work. Parts of this research were later included in the book The design of high-performance mechatronics by Rob Munnig Schmidt, Jan van Eijk, Georg Schitter and Rankers himself. In addition to the development and consultancy work and his role as group leader, he became involved in the development of mechatronics education for Philips’ own employees, initiated by Jan van Eijk. He also joined the board of the Dutch Society for Precision Engineering (DSPE) in 2008, of which he is still a member today.

Mechatronics Academy

Although he enjoyed working there in engineering and technical management, Rankers made the switch to entrepreneurship in 2010 after twenty-five years of loyal service at Philips. He wanted to focus mainly on transferring his mechatronics knowledge. This eventually led to the idea to set up the Mechatronics Academy together with Jan van Eijk and Maarten Steinbuch. It turned out that there was a need for this: the organization can now rely on sixty to seventy trainers with an industrial background in the field. Mechatronics Academy now provides training courses for around four hundred students per year. These are both open training courses and in-company training courses, specially tailored to companies.

'I like to pass on my knowledge of mechatronics to others.'

“What appeals to me in the field of mechatronics? It is always a multidisciplinary challenge where you work with people from different disciplines. Mechatronics always gives you the opportunity to immerse yourself in all kinds of things. In addition, I like to pass on my knowledge of mechatronics to others,” says Rankers enthusiastically. “In doing so, it is essential to realize that the students still have to go through the learning curve that you yourself have gone through over a number of years and that some things are quite difficult and might not be obvious to everyone. As a trainer you have to have an eye for that and take your time. In accordance with the old saying by Confucius, ‘I hear and I forget. I see and I remember. I do and I understand,’ we work a lot with exercises in small teams. You see how students struggle to put the theory they have just learned into practice and to master the subject matter, but it is precisely this struggle that is an important part of learning. If I can guide them through this, so that they eventually understand it for themselves, it gives me a lot of satisfaction.”

The trainings that Mechatronics Academy organizes are well-attended and get good reviews from the participants. But that certainly doesn’t mean you can rest on your laurels, Rankers believes. “We think it’s important to keep our portfolio up to scratch, to expand and to ensure continuity.”

'Assignments are indispensable for understanding.'

That’s why at Mechatronics Academy they are constantly working to keep the team of trainers up to strength. Good trainers who quit, because they come of age, are replaced with a new generation. To this end, they approach the best content experts in the field, whom they know from their extensive network. They also ensure that they continually adapt existing training courses to the latest academic insights and technological developments. “We adapt existing modules and develop new ones. In addition, we invest a lot in resources that we use during the practical parts of the training courses. Practical assignments, such as working on constellations or carrying out simulations, form an essential part. These assignments are indispensable for understanding,” Ranker describes.

New courses

In addition to keeping existing training courses up to date, Mechatronics Academy also develops new training courses that arise from a need in the market. Ideas for this come from Rankers, Van Eijk and Steinbuch themselves, but also from their trainers. At DSPE meetings or conferences in the field, everyone sticks out their feelers to know what is going on and where needs lie.

Through these practices, beautiful new training courses are created time and time again. For example, the training “Passive damping for high tech systems,” which started last year and has now run twice. In ultra-precise motion systems, dynamics – both loose and in interaction with control technology – play an important role. That is why in today’s practice, and therefore also in the various courses, much attention is paid to the realization of high eigenfrequencies in mechanics. Understanding mode shapes and the extent to which they can be excited by the actuator or perceived by the sensor is also important here. This approach is and remains essential. But with increasing accuracy requirements, this is no longer always sufficient. You then run into the limit of what is physically feasible. The deliberate addition of passive damping then offers extra solution space and becomes a decisive parameter in achieving extreme specifications.

The new training, which focuses on proven ways to achieve passive damping, is very successful, according to Rankers. It is a highly relevant theme in the precision engineering community. Hans Vermeulen, Kees Verbaan and Stan van der Meulen are the trainers. They have an enormous amount of knowledge of the field. The positive response to the training sessions is also reflected in the reactions of participants: “Excellent training,” “Excellent trainers” and “Very inspiring,” to name a few. “There is even interest in this training from abroad,” reports Rankers proudly.

Then there are a number of new training courses in development. From the training “Actuation and power electronics,” which focuses mainly on electromechanical propulsion, the idea arose to set up a training course specifically for piezo materials and their applications. There are also plans to set up a training course “Active thermal control.” Rankers: “How can you keep the temperature and deformations caused by heat sources manageable in a setup? Which control techniques can be used for this? What are suitable sensors for measuring temperatures and deformations with high precision? And which elements can be used for cooling or heating? These are all questions that will be addressed. The training course ‘Thermal effects in mechatronic systems’ has already briefly addressed this, but it is such an important theme in the world of ultra-precision that a separate training course would be appropriate here.”

“Our current training ‘Basics and design principles for ultra-clean vacuum‘ focuses on molecular contamination and how to prevent it. However, there is also a need for a new training course on ‘Particle contamination’,” continues Rankers. “In this training we will discuss particle contamination in vacuum. Unlike molecular contamination – for example by gas molecules trapped in a blind hole of a part placed in vacuum, which leak through the thread to the ultraclean vacuum – these are small pieces of material. These may be, for example, particles loosened by friction between moving parts of the device placed in vacuum. The knowledge from various studies that are already running in this area could serve as a guideline for this.”

'We continue to invest in support material for our training couses, to link the covered theory to industrial practice.'

“Together with our trainers, we are constantly working to improve training, set up new training courses and keep our pool of trainers up to standard,” Rankers summarizes. “We also continue to invest in support material for our training courses, so that we can link the theory we cover directly to industrial practice. This is where our strength lies: translating academic insights into industrial practice, so that trainees can directly deploy their knowledge in our high-tech industry. This is how we continue to keep our training package up-to-date and deliver the best trainers, so that we can continue to live up to the designation ‘excellent training’.”

Mechatronics Academy offers its trainings through High Tech Institute

Hittech wants employees to drive their own success

IEMC for mechatronic engineers - Testimonial Stefan Vossen
Training programs can be an effective tool for any high-tech company to attract new talent and help employees sharpen their skills. To Development Manager Stefan Vossen of Hittech Multin, training courses provide something much more important – a chance to discover your intrinsic motivation and realize your passion. Hittech Multin organized the ‘EMC for mechatronic engineers‘ training in-company.

In 1994, Cor Heijwegen stepped down as a divisional director within the Hoogovens Group. The group consisted of numerous companies that supplied Hoogovens, now Tata Steel, with tools and materials used in the production of iron, steel and aluminum. On his way out, Heijwegen and a couple of colleagues decided to start their own business comprised of several of the Hoogovens suppliers, which was called Hoogovens Industriele Toelevering (Hoogovens Industrial Supply) or Hit Group. In 2004, it was incorporated as Hittech Group. Today, the corporation consists of eight self-governing, but not independent outfits, managed by a small holding company. By design, the companies are kept small, less than 100 people, to ensure flexibility, entrepreneurship and a focus on the customer.

One of Hittech’s subsidiaries, Hittech Multin specializes in the development and production of mechatronic products for the medical, semiconductor, measurement and analytical industries. These products are subject to high qualification requirements and are often associated with accurate positioning, optics, vacuum technology, cleanliness and medical regulations. To achieve this, the Hague-based Multin branch requires a staff with a strong technological background, as well as the desire to enhance skills through training.

'To work here requires the mindset and an urgency to constantly improve and the willingness to really engage with customers.'

“It’s no wonder that the majority of the development capacity of Hittech Group sits under the roof of Hittech Multin,” remarks Development Manager Stefan Vossen. “To work here requires the mindset and an urgency to constantly improve and the willingness to really engage with customers. That’s why so many of the technological advancements of Hittech are developed in, and with involvement from, this department.”

Philosophy

To maintain the customer-oriented focus, Hittech is continually looking to shake things up and employ out-of-the-box thinking to adapt and better fit its customers’ needs. After all, its mantra is “masters in improvement”. One tool the systems development company uses to ensure this is training. “I have a different kind of philosophy when it comes to training. I’ve noticed a number of times when attending my own courses, there’s a stark difference between those that are motivated to be there and others that are obligated to attend,” recalls Vossen. “The truth is, if you’re not intrinsically motivated to be there, you’re not likely to get anything out of it.”

Vossen himself started his career as a scientist at TNO, specializing in electromagnetism. While at the institute, he became interested in coaching others in their professional trajectories. “It was a rather steep growth track, but I attended multiple trainings on coaching. In these courses, I learned so much about myself,” illustrates Vossen. “That’s where I discovered that I really enjoy working with younger people and trying to help them further their career. That’s when I became a team manager and really found my passion for coaching and mentoring young talent. And ever since, that’s where I’ve tried to put my energy.”

Driver’s seat

Another aspect to Vossen’s philosophy on training is that there will never be a fixed course program in his group. Rather, training programs should be tailor-made to custom fit each member. “It really comes down to the needs of the person, of course, within their role on the team. I want to see them be enthusiastic about something and decide for themselves,” says Vossen. “I shouldn’t be in the driver’s seat of their career. That has to come from them, with their own vision and their own interests. I think taking courses is part of that.”

It seems like the approach is paying off. According to Vossen, over the last few years, product development at Hittech has been undergoing a transition. When the company was founded, the focus was on materials knowledge and construction principles, but now, it’s centered on moving mechanisms and mechatronics, combined with optics, electronics and software. “As a company, we’re offering fully integrated products. But with this transition, we’ve really had to intensify the systems engineering within the group,” expresses Vossen. “This shift meant we needed to adapt and improve our capabilities and I had a number of our engineers requesting to enroll in training courses.”

ROI

Recently, there was such an interest in an EMC training course that Hittech decided to commission a company edition of High Tech Institute’s “EMC for mechatronic engineers”. “When we select training courses, we don’t want a standard, textbook type of course. It’s important for us to find trainings that are taught by people with deep roots and experience in the high-tech domain,” highlights Vossen. “That’s really why we turned to High Tech Institute. Their trainings are designed for the industry by experts in the industry. It gives me a great level of comfort when arranging these kinds of trainings, as I know the content is always reliable.”

A training, however, is meaningless if it doesn’t lead to results, and of course a return on the investment. Though this can sometimes be difficult to quantify, for Vossen, the data is clear. One specific place he’s noticed marked improvements is in the early stages of system design. Vossen: “I’ve seen that our engineers often come back from training with a fresh new perspective. I notice this particularly in the beginning stages of project planning. For example, in the process of setting up error budgets, the engineers are taking more details into account, specifically with an eye to possible EMC-related issues, very early on. In the past, however, they might have missed these potential issues altogether.”

“Another benefit that I attribute to my employees participating in training programs is that it seems to help foster communication. Specifically, between those working in groups that consist of engineers from the various disciplines. They seem to understand each other’s needs better and hence take each other more into account from the start. And while no project is perfect the first time around, the better your specs and conditions are at the beginning of a project, the better and smoother the project is sure to go.”

Recommendation by former participants

By the end of the training participants are asked to fill out an evaluation form. To the question: 'Would you recommend this training to others?' they responded with a 8.3 out of 10.

Then I immediately see how the material lands.” Because of this, the pace of this remote classroom is a bit slower, according to Wendy. “In classroom trainings, I talk to people and it’s easier to look over shoulders.”

When I called her on the evening of the second day of the training, Wendy said that she was quite tired the day before, but that it was already getting better. “It takes some getting used to. Hopefully, it will continue this way over the next three days.”

During Wendy’s presentations, the cameras of many participants are off. In part, they do this to squeeze the highest quality video and audio out of the connection. But it has also been common practice for many years for remote consultations. Wendy: “At video meetings, people say hello at the start, then we have a suggestion round and then, the cameras go off. With video view, the tension curve is also more intense.”

Furthermore – and this was also to be expected – students do not automatically look for each other during breaks for social interaction. In the classroom version, there is usually a positive vibe at the coffee machine. “Now, that’s almost gone,” says Wendy. “If I want them to look for each other, I have to give them a push. It’s something to remember for next time.”

'They have to learn to make decisions at the CAD drawing level because it's only a design when you can draw it.'

The Cooling of Electronics training course is strongly practice-oriented. “People often run into very practical issues in their work. They often have more than enough theoretical background, but are faced with very simple decisions: where should the gap be, or how much space needs to be saved? Therefore, my training is quite concrete. During the exercises, people work with a spreadsheet because that is sufficient for a first-order assessment. They have to learn to make decisions at the CAD drawing level because it’s only a design when you can draw it”.

Wendy estimates that she spends about 60 percent of the time ‘sending’ (lecturing), while the other 40 percent of the time, the students spend 40 doing exercises. Initially, she planned to save exercises for the end of the day. In the meantime, however, she has noticed that it’s best to go between theory and practice. “And it works well to turn on the cameras during the exercises.”

Because of the excellent preparation, there were no technical issues. However, there was still a small bump. Wendy and program leader Hans Vink sent the material via WeTransfer, but some companies do not allow the use of this tool for large digital mail items. The solution was simple: the participants concerned solved it via their private email address.

This blog is the second blog of a series in which we share our first experiences with online training.

System requirements defined by cascades of creativity

System requirements engineering trainer
With more than 30 years of experience with some of the top names in the Netherlands’ high-tech industry, Cees Michielsen reflects on his lessons learned and how he tries to relay this knowledge as the instructor of the “System requirements engineering improvement” training at High Tech Institute.

It was 1986 when Cees Michielsen got his start in the world of high tech. At the time, he joined the Philips EMT team, which would later become Assembleon and finally Kulicke & Soffa, to help build SMD placement robots. “Back then, our main customers were automotive companies like Ford, GM and Chrysler. We were completely self-contained and had all the essential disciplines and competencies in our business unit,” Michielsen recalls.

Then he entered the team, Michielsen’s focus was on technical informatics, but early on, the trajectory of his career took a detour. “It was there at Philips that I started to develop into a systems thinker, and really got away from my own software discipline,” expresses Michielsen. “In hindsight, I can say that was the best start for me in my career; the experience gave me an enormous head start and is why I’m still so passionate about it today.”

System requirements engineering trainer
“It was there at Philips that I started to develop into a systems thinker, and really got away from my own software discipline,” expresses Cees Michielsen.

Now, after more than three decades in the industry, Michielsen is spending his days as a requirements engineer at ASML, as well as an instructor at High Tech Institute where he shares his knowledge, and his many lessons learned, with the next generation of engineers in the “Systems requirements engineering improvement” training.

Abstraction layers

In systems requirements engineering, especially at the system level, scoping the problem is the name of the game. It’s about determining exactly what functions the system should have, the specific properties that are tied to those functions and accurately defining the problem being solved. “If we’re, for instance, talking about projecting patterns on wafers, you can imagine that’s the main function of the system, and several companies might be doing the same thing. But it’s the properties of this function that distinguish one group from its competitors – the accuracy, yield, speed and reliability,” highlights Michielsen.

For Michielsen, it’s these characteristics that make all the difference in the world, and requirements engineering is the art of identifying the right functions and quantifying their properties to define the problem. “Once the problem is well-defined, finding the solution is much easier,” Michielsen points out. “But you’re not going to find the implementation of your solution straightaway, so you’re probably going to go through a number of abstraction or decomposition layers.”

Cascade

During his training session, Michielsen explains that, in a system, the highest layer of abstraction is the level with the most general requirements, ie the system needs to be fast or have a certain look. But as you go down deeper into the system, it gets much more detailed. Suddenly, the layers are referring to different subjects or using different languages to express the requirements, which can be a little tricky for engineers to keep the information flowing.

“That’s the real objective of requirements engineering, finding different ways to ensure that the data continues to cascade from top to bottom and from stakeholder needs to implementation, all without losing any information,” suggests Michielsen. “I think if I were to summarize the challenge for requirements engineering, I would say that it lies mainly in the cascading of information throughout each abstraction or decomposition layer.”

Quantification

According to Michielsen, one very important part of the method is to find the complete set of requirements for a system. “The question quickly becomes, ‘when is the set complete?’”, he poses. “The best approach we’ve seen so far can be expressed using an equation, which we share in the training. It allows us to fully define a system by its functions, properties and constraints, and can be applied from the highest levels to the components and parts at the lowest points.” He continues, “By specifying and quantifying these criteria, the true requirements can be derived. This is one of the main steps of the training, learning how to put a value on each of the properties of the system.”

“Once the goals are defined, we can identify solutions – design options – based on assumed capabilities of subsystems. This is where creativity leads the product development process, as many different options are considered for solving the problem,” Michielsen depicts. “As long as we document the assumptions that are made during that creative design process, we can later translate these assumptions into requirements for the lower-level subsystems that we need in the solution.”

Justification

To Michielsen, this is one of the most powerful elements of the whole method. The ability to see the complete line of logic from a quantified system definition to the design decisions and finally to the specific implementation of a solution. That is, if engineers are able to maintain coherence between system requirements, system design and system decisions – a crucial factor.

“As long as the information feeds properly, we can derive requirements for the next layer and continue the cascade. That way we can ensure that whatever requirements we end up with at the lowest component level, through our method and our traceability, we can exactly come to the justification of each requirement and each decision made throughout each layer. That’s the whole essence of the method.”

Trainer System Requirements Engineering
“As a trainer, I want to help instill confidence in the process”, says Michielsen.

After more than 30 years in the industry, what do you most want to share in your trainings?

“As a trainer, I want to help instill confidence in the process. Following the method is one way to achieve that, because the students get the feeling that the system can be complete, consistent and correct – in terms of specifications. That can really help it feel less daunting. Once you cross that hurdle, the students can almost immediately start determining the main functions of the system and decide what properties are related and which constraints apply at that level. By quantifying these aspects, they don’t just state that the system should be reliable, they say explicitly just how reliable the system should be.”

Lessons Learned

With his 30+ years in process architecting, Michielsen has developed several practical methods to keep the information flowing from layer to layer. His success in the field opened the door for him to work with top Dutch and European companies, like Prorail, Eurocontrol, Punch Powertrain and Vanderlande – and several others, to help establish and implement processes for their own requirements engineering programs. “What I found was that there are enormous differences between each company, especially in implementation,” recollects Michielsen. “When I went to work for DAF, we put in place a complete requirements engineering process in three years’ time. We could successfully train hundreds of engineers and the method was paying off.”

'It certainly was a big learning experience for me, and it came with a lot of tough lessons learned.'

Noting the success of the DAF project, Siemens called to lure Michielsen to Germany to help establish the same approach for Daimler. “It was a huge step for me to be invited to implement the system, but it quickly became clear that the approach we developed at DAF wasn’t going to be transferrable to Daimler,” Michielsen calls to mind. “Daimler was just organized in a completely different manner, with responsibilities being spread among departments and people in a way that made successful execution really difficult. The inability to get something going there was disappointing,” he says, continuing, “It certainly was a big learning experience for me, and it came with a lot of tough lessons learned.”

Are these lessons learned what drives you in this domain?

“In part, yes. I have an enormous passion for this whole process. I want to help improve product capabilities and productmanufacturing capabilities, especially in the area where I live and work. I want to make an impact on industry in that sense because we’ve learned so much and I want to spread this information,” emphasizes Michielsen. “It’s not all my doing, it’s all the companies I’ve worked for and all my experiences. I’m extremely grateful for being able to do that, and I’d like to spread that knowledge to make sure that the entire ecosystem can benefit, and we grow from it.”

High Tech Institute introduces you to the first online participant for Cooling of Electronics: cat Okkie

Electronics training by Wendy Luiten
After a lot of preparation and sometimes a bit of fiddling, the time has come. In the last couple of weeks Wendy Luiten was practicing her first remote Cooling of Electronics training with her cat Okkie as the first participant. “Of course I’m regularly in team meetings but providing a training is something else”. As of today the online edition starts.

Wendy already gained experience with online training two days after the lock down. “I heard on Tuesday at 8 a.m. that Philips employees had to work from home. On Thursday was the last day of the already running Green Belt training at Philips. So we immediately switched to online on  Teams. At that time I had two advantages: I knew the students and they were used to online meetings via Teams”.

This week is different. The eight participants of “Electronics cooling thermal design” don’t know each other and some of them didn’t use Teams before.

'It's a trial run, there are always areas for improvement, and you won't find out until you try.'

Wendy’s unconcerned about potential problems. She sees tooling and in particular Microsoft’s applications as a natural phenomenon. “It is working and then we’re happy, sometimes it is not working” she says. “In my experience, the ancestor Skype always worked. Teams is more recent, but meanwhile widely deployed everywhere. In the US there are clusters of universities and schools on the educational version. I have no reason to believe that it will cause problems this week. It’s a trial run, there are always areas for improvement, and you won’t find out until you try.

In order to make the material suitable for online modules, Wendy went through all files again. The slides, the practice exercises, the case study. “From a distance, the storyline and story telling becomes more important, because you can’t see exactly how the material lands,” she says. Incidentally, Wendy isn’t going to use the special version of Teams for Education. “That doesn’t add any value for me or the participants. With the educational version, people get an email address and access to share-point, among other things. Students then have to work with user aliases and so on. This puts a burden on IT that you don’t want for a few days of training”.

About the preparation of the participants: High Tech Institute’s partner for electronics courses Hans Vink personally approached all cooling participants three weeks ago. After all, everyone knows the hassle when you end up in a new video conferencing environment with a group for the first time. Do you see me! How do I mute my microphone? These kinds of things. Hans wanted to avoid that at the Team sessions. By the way, we looked at a whole bunch of potential video tools with the High Tech Institute team, but more about that later.

For some clients, Teams is the standard application for meetings, but for others it’s not , so they participate via their web browser. Hans asked all participants whether or not they use Teams and then did a test session with everyone via app or browser to check the settings and to see if all facilities work as needed in the course.

All preparations – don’t hesitate to say: also a lot of extra work – now provide an up beat vibe. Based on the feedback, Hans expects that we will be able to organise online courses every year, as well as the classroom course. “That wouldn’t surprise me”, he says, “We already have sufficient participants for the classroom course in mid-November”.

With that, Wendy’s satisfied too. She regularly receives training requests from all over the world. Offering online modules lowers the threshold to train technology professionals from for example Silicon Valley or India.

This blog is part of a series in which we share our first experiences with online training.

90 years of sensing and control – and now machine learning

Skillsets training - Testimonial from Omron
Driven by the needs of society, Omron has spent nearly 90 years developing innovative technologies to enhance people’s daily lives. According to the company’s European R&D manager Tim Foreman, this takes a commitment to keeping employees challenged and motivated by helping them enhance their skillsets with training. High Tech Institute provided a mixture of its soft skills & leadership trainings.

Perhaps you’re not familiar with Omron, but one thing for certain, you’ve benefitted from its technology. From its first innovation of accurate x-ray control timers, to the magnetic strips on credit cards, early ATMs and digital blood pressure monitors used at doctor’s offices – the company has been at it for more than eight decades. “Our philosophy has always been, to create value based on the needs of society,” describes Omron’s European R&D manager, Tim Foreman. “Society changes, and we’re continuously adapting to find innovative solutions to newfound issues. That’s what keeps us at the leading edge.”

Employing some 40,000 people around the world, Omron has received numerous recognitions, including a spot on the Derwent Top 100 Global Innovators by Clarivate Analytics and a top ranking on the Dow Jones Sustainability Index, which uses several indices to track sustainability efforts by publicly traded companies. “To make it on these lists is a great honor for us at Omron,” expresses Foreman. “It shows that not only are we among the innovation leaders in our field, but as a company, we keep our focus on the environment and do it in a smart way.”

Tsunagi

Originally known as Tateishi, the Kyoto-based Omron has built its foundation on two key technologies: sensing and control. For instance, remote control devices in automobiles that detect your proximity to your vehicle, before automatically unlocking the doors as you get within a close distance. “It was these electronics components, the switches and relays inside of devices, that really got the business going,” explains Foreman. More recently, as technology has advanced, the company added a third core focus, referred to as “think,” aka machine learning.

The spotlight, however, isn’t simply on developing individual products, it’s about providing outstanding customer service. Behind the core technologies of Omron is for example the service known as Tsunagi – a Japanese word that translates to “filler”. “Tsunagi means that in your house, if you find a crack in the wall, you fill it in and repair it,” illustrates Foreman. “In the electronics business, it’s common to source parts from different vendors. Perhaps you choose Omron’s IPC, but another company offers you a highly specialized sensor that you need. The two parts should be compatible, but sometimes the user will get an error message. Rather than place blame or leave the customer to contact others, at Omron, we look to fill in the cracks. We tell our customers, no matter the issue, call us. We’ve put together some 400 small manuals to make systems work seamlessly and to provide expertise in interoperability – that’s tsunagi.”

Stakeholder management

With a portfolio of more than 200,000 products, Omron’s focus on interoperability and integration is a crucial part of the business. Not everything can be perfectly integrated, and when you’re dealing with different global offices, that can get tricky. An example, a safety sensor developed in Italy needs to work seamlessly with a control device developed in the Netherlands. This relies heavily on the communication abilities between the groups. “If the two sides fail to talk, it becomes immediately clear to our customers,” says Foreman. “That’s why we place a real emphasis on communication during the entire development of new products. When things are seamlessly integrated, our customers can clearly see the benefit of what we offer.”

'In the high tech world, conveying your message effectively is an essential piece to the puzzle.'

To achieve enhanced communication between units, Omron’s R&D manager turns to trainings and courses. “We have some incredibly bright employees at Omron, all of them very technically gifted, be it in software, mathematics or electronics. But while their technical skills may shine, it’s a much smaller percentage that also have strong social skills,” clarifies Foreman. “While especially skilled, our engineers sometimes don’t have the tools or experience to effectively convey their message. In the high tech world, that’s an essential piece to the puzzle.”

“You have to know how to sell your story and motivate others on the team. Furthermore, when you know you’ve got a good idea, you need to know how to approach upper management and convince them. It’s all about stakeholder management – a very expensive and very important term,” continues Foreman. “That’s why we turned to High Tech Institute to help us create Omron’s Talent Academy Training. They speak the right language; they understand the ecosystem and help give our boys and girls the tools to greatly improve on these skills and others.”

Motivation

This isn’t the only benefit that Foreman sees with training his employees. “It’s really just a question about how you keep talented workers, especially in the competitive high tech industry. The answer is simple: you’ve got to keep your people motivated. But how do you do that? Of course, you start by giving them a good salary, but that’s not enough. It’s done by giving them interesting challenges that apply to real-world issues and offering them state-of-the-art tools, equipment and training to tackle these issues,” claims Foreman. “It’s about creating a working environment where they can have fun and enhance their personal knowledge and skillsets. When these criteria are met, it shows in the final product and ultimately, improves its popularity on the market. What better motivator is there?”

It’s precisely these efforts to retain its talented workforce that are perhaps more telling than the total number of workers employed by the electronics company. At Omron, there are some workers that have been with the business for more than 30 years already. “These people have spent thousands of hours with their machines. They can be 10 meters away from them, hear an unusual noise and instantly know what the problem is,” boasts Foreman, himself a 26-year employee of the company. “But to be perfectly honest, that’s not a modern practice anymore. Nowadays, employees want to get a variety of experience – to try a little of this and a little of that.”

Omron’s solution: offer its employees broad access to various trainings for individual improvement. At the same time, the company works in-house to develop and apply computer learning models that allow machines to learn from the experienced operators. “The machines can then fill in the gaps and help guide a newer generation of operators,” suggests Foreman. “That’s the sort of technologies we’re currently working to develop at Omron.”

Building a foundation for the Dutch high-tech ecosystem

Consultative selling training - Testimonial from NTS
Despite competition from China and the US, the Netherlands continues to play a major role in the world of high tech. Patrick Strating of NTS believes it starts with high-tech companies that have close ties to top-notch technical universities and continues with ambitious workers that thrive on life-long learning through training. NTS organizes the Consultative selling training from time to time.

Roughly five years ago, NTS started on a new mission: to become a leading supplier of machine equipment for the world’s top OEMs. In order to achieve this, the Eindhoven-based company set out on a series of acquisitions to bring in all the necessary expertise and abilities to build high-precision parts, equipment and machines. “Our aim is to function in the state-of-the-art domain and beyond, where technology boundaries are pushed,” explains NTS’ Technology Manager of Development & Engineering, Patrick Strating.

With this ambitious plan, however, comes a unique set of challenges to overcome. As NTS grew, it was composed out of a number of individual satellite locations, each with a different focus and expertise – which can be difficult when trying to build a cohesive team and vision.

“Ours is really a story of integration. NTS has been built up from separate entities. They were suppliers of frames and sheet metal, suppliers of precision metal parts and several engineering units of different kinds,” describes Strating. “To become an integrated equipment supplier, you need to master the complexity of the entire development and manufacturing chain. That requires much more than just skilled people executing supply chain work or doing machining on metal parts; there’s a need for employees who are fully technology-savvy and context-aware, and who can work with complexity while maintaining an eye on what our customer wants.”

Proactive

Realizing the task at hand, NTS adopted a two-step solution. First, educate its workers from both the company and customer perspective of the new reality of being a first-tier supplier of specialized systems. Second, look to the labor market to find emerging talent with modern skills. “To understand the complexity of the machines, we needed a gradual buildup of both training of existing people, as well as attracting new people with more advanced multidisciplinary skills and a passion for life-long learning,” highlights Strating.

“At NTS, we offer a robust employee training program with individual coaching, technical mentorships and training. In addition, we have programs to stimulate craftsmanship at our manufacturing sites. We see it as a necessity to offer extensive training because it gives our employees a sort of basis or foundation in technical areas. But our true hope is that it also inspires them to continue broadening their scope, continue learning and to keep moving with our customers. We work with challenging companies like ASML, Philips and Zeiss, so it’s imperative that we’re keeping up to speed with them and even helping guide them with our expertise.”

To establish and preserve their expert knowledge, the workers at NTS often attend technical trainings in optics, mechatronics and systems development. Perhaps somewhat surprising, however, is the benefit the company sees by emphasizing social trainings like soft skills and sales. “Take the consultative selling for technology professionals training. That’s really about understanding your product and how it relates to the customer’s needs and values,” Strating illustrates.

“It’s been a part of NTS’ migration. Five years ago, as a supplier, we were more in a reactive mode. A customer would come to us with an issue and we would spend a lot of time in discussion to fully understand what was needed. Now, we can be more proactive. We go to work with our customers and really trying to elevate knowledge and innovate alongside them. Having a sound systems engineering basis and speaking the same language as our customers allow us to bring our manufacturing expertise to the table. In the end, our customers want critical equipment to be delivered, and our broad-based yet detailed manufacturing expertise is our key asset.”

Would you say that training is a tool for staying ahead of your customers?

“Not necessarily. For some trainings, that might be true. But for the more conventional courses, like mechatronics or systems engineering, what’s really needed is to establish a common base. Our engineers need to speak the same type of language as our customers,” expresses Strating. “You find that there’s this sort of specialized lingo and common approaches to issues in our industry, and this is really where the value is in technical training. But this doesn’t just serve NTS, it serves the entire high tech ecosystem of the region.”

Competitive

Strating believes the Dutch way of working is a real point of differentiation compared to other regional ecosystems. To him, the Netherlands and Belgium are very connected, communicative, competitive and collegial. “More or less, we depend on one another because we all supply each other. Of course, we can be competitive, but in the end, we’re all working with the same customers and they benefit from the cooperation and alignment of their suppliers,” says Strating. “Dutch companies are continually exchanging ideas, best practices and personnel. We find that if we continue to do things better if we share a common language in terms of technology and engineering methods, and if we have common people that demonstrate agility to address gaps within our ecosystem, it helps us compete with larger-market supply chains in China and the US.”

'High Tech Institute has strong roots within these universities and is able to incorporate modern technology approaches in their high-quality, professional and technical trainings.'

In describing how the culture of Dutch high tech was built, Strating points to the role of the technical schools. “I think the three technical universities form the high tech basis in the Netherlands. They’re responsible for shaping our future innovators and providing them with the common building blocks to succeed in this industry. I think as companies, it’s important that we continue to recognize that, but also work with these institutions in various forms of industrial cooperation,” voices Strating. “That’s one reason we turn to High Tech Institute for training. They have strong roots within these universities and are able to incorporate modern technology approaches in their high-quality, professional and technical trainings. That’s an important criterion for us.”

Flexible

Looking ahead to the next five years, NTS’ ambition is to use its expertise to lead the way in combining high-tech engineering with manufacturing. This will require highly trained workers that can understand not only the customer’s needs and challenges, but also have the ability to go through the engineering cycle and connect customers with their roadmap, all the way to the end-user.

“We want to bring together the worlds of customers, technical people and high-precision equipment. This will require incredibly talented and creative workers that are willing to really stretch technology to bridge the gaps. Those people are not so easily found; they have to be developed and that’s what we believe training and coaching help us achieve,” states Strating. “Training courses are important pieces of the puzzle. They’re instrumental in creating those flexible people that have a technical mindset and want to make a difference by understanding and optimizing this entire chain. That’s where we want to excel. That’s how we will grow the NTS market position as we look to be the best at playing this complicated global game.”

Opto mechatronics in Eindhoven is top notch

Mechatronics courses - Testimonial Technical University Denmark
Eight years ago, DSPE started a certification program for training programs in the field of precision engineering. Three years ago, Nikola Vasiljevic was the first to meet the requirements of a bronze certificate. The mechatronics courses he took during his promotion had a great effect on his career.

In 2011, the Dutch Society for Precision Engineering (DSPE) took the initiative for a certification program for postgraduate education. The aim was to strengthen the offer by certifying training courses in precision engineering. The initiative arose when two years earlier, the Philips Centre for Technical Training was discontinued and the educational programs fragmented, partially disappearing. The Dutch high-tech sector could not afford such a loss, according to the industry organization.


Nikola Vasiljevic did his PhD research at the Technical University of Denmark. He designed, developed and tested a mobile, long-distance infrastructure for atmospheric and wind energy research.

DSPE decided to map out the entire range and monitor its quality by setting up a certification program. Candidates can attend certified training courses, for which they earn points (approximately one point per course day). A total of 45 points would yield the title of Certified Precision Engineer (CPE). This was later split into a bronze certificate for 25 points, silver for 35 points and gold for all 45 points.

In 2016, Nikola Vasiljevic was the first to reach the bronze level. The Serbian researcher obtained a PhD at the Technical University of Denmark (DTU) in the Department of Wind Energy. He designed, developed and tested a mobile, long-distance infrastructure for atmospheric and wind-energy research. His system, known as the Wind scanner, is based on multiple scanning wind lidars used to map the wind flow.

Vasiljevic’s background lies in electrical engineering and computer science. For his PhD project he was looking for a good course that would provide fundamental and practical knowledge about motion control tuning. He felt he lacked knowledge about a number of the practical aspects of his work. By chance, he got to know the mechatronics courses of High Tech Institute.

Travelling to Eindhoven was a long shot

High Tech Institute offers the vast majority of CPE-certified courses. Vasiljevic’s main reason for joining his first course was the way the subject was presented. “For opto mechatronics, there is a lot of literature available, but it is difficult to use it in practice,” he says. “Most of the courses I have taken now have focused on the practical aspects of designing complex opto mechatronics devices. That’s how I always learn, ie by building things and understanding them in practice. For more detailed knowledge I read books and professional literature.”

Because he knew the position of the Eindhoven region in the high-tech industry, Vasiljevic took the gamble and enrolled for the first course at High Tech Institute. “Opto mechatronics in Eindhoven is top notch compared to the rest of the world. Many of my electrical engineering friends from the University of Belgrade came to Eindhoven to obtain a PhD or to work at Philips,” explains Vasiljevic. He thinks the high-tech industry in Eindhoven is very healthy. “You don’t often see such a degree of exchange between different companies. People regularly move between companies within the region, thus contributing to the exchange of knowledge. Despite the competition, there is also a certain degree of openness.”

Balanced

Motion control tuning, the first course Vasiljevic took, was a great experience. “I was amazed at the knowledge I gained in those six days. The course was a balanced mix of theoretical and practical aspects of motion control tuning. That is what led me to go further and look at other courses, such as Advanced motion control tuning,” he describes.

After that first course, Vasiljevic followed a number of additional mechatronics courses. “There were other mechatronics courses that appealed to me, such as Experimental techniques in motion control tuning and Metrology and calibration of mechatronic systems. My background is in measurement techniques, the development of wind sensors and metrology, so almost the entire curriculum applied to my subject,” Vasiljevic highlights.

At his own university in Denmark, Vasiljevic would probably have had to take a full semester course to acquire the necessary knowledge. Moreover, he feels that the practical aspects cannot be taught by ordinary academic professors. “The teachers at High Tech Institute have years of experience in the industry. They have built up practical knowledge, supported by theory.” DTU required Vasiljevic to earn points for the European Credit Transfer System (ECTS). “I could use the CPE courses for that.”

The next course Vasiljevic took was the Opto-Mechatronics Summer School. He had just received a grant from the Marie Curie scholarship which offered sufficient funding for five additional courses, covering nearly all the remaining subjects of opto mechatronics, with the exception of software development.

Knowledge and networking

After his promotion, Vasiljevic hoped to create a second generation of the long-distance Wind scanner system. Unfortunately, that did not happen. Nevertheless, the courses have yielded him a lot. Especially in the networking part of the courses. “I became friends with Adrian Rankers and Pieter Nuij, both teachers at High Tech Institute. We keep in touch on a regular basis.”


Vasiljevic about his first training at High Tech Institute: “I was amazed at the knowledge I gained in those six days.”

In total, the investment was comparable to what you would need for an MBA degree. “It’s a fine testament to your abilities.” That being said, Vasiljevic thinks he has not yet managed to make full use of the knowledge he has gained because he has not created the second generation of his tool. “Still, I’ve improved the device with all the knowledge I’ve gained.”

After his promotion Vasiljevic considered looking for a job in Eindhoven, but in the end, he didn’t find a good match. “HR departments like to have standardized people who come to work in their company. Because I do things differently, from software development and optics to control and data science, far beyond the role of a narrow specialist or a system architect, it is difficult to label me and place me in pre-defined business templates,” illustrates Vasilijevic.

'That's why I think researchers today are more capable and better able to adapt than preformed R&D engineers, who are favored by HR managers.'

Currently, Vasiljevic is still working in the research world. “Being part of a research environment, especially in the field of technology and engineering, requires that you constantly build up new skills and knowledge because it is the only way to survive in a landscape where funding is scarce,” depicts Vasiljevic. “That’s why I think researchers today are more capable and better able to adapt than preformed R&D engineers, who are favored by HR managers.”

European expansion

Vasiljevic finds it difficult to identify a single aspect of CPE certification that is most valuable to him. “I’d say, it’s a mix of everything. Practical knowledge, which is a good basis for continuing to learn. Working in groups of up to twenty people and getting to know the teacher. Networking between colleagues.”

He is convinced that the ECTS credits he received from his CPE training have influenced his career in an extremely positive way. “I’m about to become a senior researcher. Also, in the Wind Energy department, I am considered an optomechatronic and the go-to person for problems with movement systems.”

Looking ahead, Vasiljevic wants to use his experience in opto mechatronics in such a way that one day he will take on a role as system architect and designer of new and exciting opto mechatronics. My main concern is that if I don’t use the knowledge I have gained, it will eventually evaporate,” he expresses. “Maybe one day I will work in Eindhoven, in the heart of the high-tech industry.”

The CPE certification program is currently being extended to the European level. Together with Euspen, the European equivalent of DSPE, some courses from other European countries are now also certified.
