In the CreateLab at Fontys-ICT in Eindhoven we play (and learn) about robot programming, behavior trees, ROS. This robot is part of professorship High Tech Embedded Software lead by Teade Punter. A late night experiment by Kris and Edwin. Empowering Students through Hands-on Learning and Repairing Robots At Fontys-ICT, we believe that hands-on experience in repairing equipment is not only an essential skill but also a powerful tool to inspire our students. Recently, an instructor and a student teamed up to disassemble and restore a Sawyer-Robot by RethinkRobotics to working condition. This collaborative repair process ignited enthusiasm and boosted the confidence of our young, aspiring engineers. Once the robot was reassembled and operational, the students quickly began exploring its capabilities. In no time, they were using its vision system to locate blocks on a table, pick them up, and stack them on a stool. This experience sparked a flurry of creative ideas, as students brainstormed various real-life applications for the robot, such as assisting disabled individuals, identifying people using facial recognition to throw bottles to them, and helping out in the kitchen. While unconventional and intense, this approach to education has proven to be highly effective, fostering a sense of empowerment and fostering an environment where ideas flow freely. We're proud to offer such hands-on learning experiences to our students, helping them unlock their full potential as engineers and problem solvers.
A friend gave me a Denon DHT-T100 to look at. Do not spend much time on it.. ok. It had a problem, it started clicking and ticking after power on, and after some time. (a so called intermittent problem) Sometimes it did not tick or click, but it was basically not usable. The clicking had a sharp click in one channel and repeated after about a second, then sound recovered and it would click and drop out again. He told me, do not spend any time on it, yeah, right. ;-) like I would give up after 15 minutes. I wanted to know what was going on with this thing, I found some schematic online and started measuring the usual things. The power supply, 24V did it drop down when a tick occurred ? Difficult to find out because sometimes the thing would play for hours without a glitch. I eventually found out the 24 V PSU, the step down SMPS on board and the LDO's were all ok, all power rails remained within spec, but it still glitched sometimes. (while power was ok) I investigat
