Although I think this is a really cool suggestion, I would also tread lightly. I used to work for a company that was heavy on the engineering side and we had a few of these robots that we used for testing products, some light production work, and various other tasks. 99.9% of the time everything was great, but there was an occasion where someone who was not properly trained was injured pretty badly. This is also a company full of engineers who are masters at these types of machines. When putting this technology into a group of people with possibly zero knowledge of its capabilities, be careful.
