I almost crushed my hand underneath a Robot while I was moving it around a couple weeks ago. It's a bad idea to use your hand to see how much space is between a part and a conveyor belt, and then move the robot closer to the conveyor belt.
I kinda froze as my hand sat there trapped between the robot and the belt. I had to think carefully about what direction I needed to press in order to not crush my fingers.
