I was just a TA, but the big issues for my professor were cost (a lot of arms cost 1000+, so if you’re buying 30 then that’s $30k+ which is hard to budget for) or it was number of axis. Since it was a class he wanted more motors, which made the arm more complex and more similar to the real world. Counter-intuitively to teach someone about robotics you want an arm that’s complex so students have more to learn, students would have to implement their own kinematics and some of the affordable ones were too simple. I never heard him mention anything about motor safety, and when we had to fix them we would often buy stronger, metal gear servos as replacements.

I love the product though, and I appreciate your input!
