On January 21st (13.45-14.15), Geir Hovland will present an approach to optimization using brute force on a GPU. Code examples to experiment with the techniques presented will be shared in the SFI Offshore Mechatronics Github repository. Use this link to attend.
The topic for our webinar on February 4th (13.45-14.15) is real-time containers. The topic will be presented by Florian Hofer which is in his last year of his phd project at Free University of Bozen-Bolzano. His research is related to using (Linux) containers (e.g. Docker) for real-time industrial control applications.
Florian will present some of the motivation for this approach, introduction to important considerations for real-time Linux and containers as well as experimental results. Florian has recently been a visiting researcher in the iCyPhi project co-funded by Siemens, Toyota and Denso. You can find one of his most recent publications here.

The Robotlab has been designed and built as part of SFI Offshore Mechatronics and in particular WP3. The robots was donated by ABB as an in-kind contribution in the project.
The following equipment is available in the lab:
- 6-axis ABB IRB6600-2.55 Robot
- 6-akse ABB IRB1400-1.44 Robot
Atle Aalerud and Joacim Dybedal actively used the lab and the equipment as part of their Phd work. We are happy to observe that the lab is also an enabler for new projects and initiatives outside of SFI Offshore Mechatronics. Currently UiA researcher Martin Choux is using the Robotlab to test dismantling discarded battery modules (news story in Norwegian only).
New equipment for acoustic emissions and a seal test rig have been designed and installed in relation to WP5. The acoustic emission equipment consists of an AE sensor, preamplifier and one channel of an ASIP-2 (dual channel acoustic signal processor). With this equipment multiple AE signals and features can be measured. The seal test rig shown in the image below is intended to investigate failure mechanisms, detection methods and remaining useful life prediction of the seals for hydraulic cylinders. The test arrangement consists of a pressure chamber connected to an electromechanical cylinder.
For questions concerning the equipment get in touch with WP5 leader Thomas Meyer.
In the fall 2020 we scheduled short webinars on Teams every second week. The motivation was initially to compensate for the cancellation of the annual conference and workshop. As a side effect we anticipate that the webinars will also result in increased interaction in the center outside of our major events. We have had good attendance with 15 attendees on average. Attendees is a mix between SFI affiliated researchers, from the industry partners and the mechatronics department at UiA. We will continue with the webinars in 2021 every second Thursday from 13.45-14.15.
The preliminary program for Q1-2021 (subject to change): 21/1: Optimization using brute force on GPU (Geir Hovland, UiA)
4/2: Real-time containers (Florian Hofer, Free University of Bozen-Bolzano)
18/2: Introduction to Julia programming language (Mattias Fält, Lund University)
4/3: CI/CD toolchains (Sondre S. Tørdal, UiA)
18/3: ONNX – Open Neural Network Exchange (Fabian Bause, Beckhoff)
The same Teams link will be reused for every webinar. A short intro to each webinar will be published in our webinar page. Get in touch if you have a topic you want to suggest or if you have a topic you want to present yourself in a future webinar.
