Agreed on the risk for robots, we deployed a robot to execute rapid scanning tasks and building safety required it be in a giant metal cage where no one could be within range of it striking or throwing something at someone. Once you get building facilities involved that cost suddenly goes up because you’ll have to bring in a contractor for all of the additional wiring and construction work.
RE slippyfish’s comment - students who understand how electronics work at a very basic level can often make more educated decisions about how something should function or work. Think of some of those electronics kits for kids - once you understand how a servo or LED or PWM controller responds you can start to understand how to build complex experiences and behaviors. That becomes ultra useful for ID students because now you can actually prototype your robotic soda machine, test the experience, and learn from that prototyping cycle. Compared to the kid who makes an awesome surface model of a robot soda machine and then says let the engineers figure out if it will work.
(FYI I can’t tell how many times I was able to out-pivot engineers who refused to do something as part of my design by having that basic knowledge and them admitting it wasn’t that complicated, but they really didn’t want to do it).
