A couple of comments:
- Keep away from small children - always good advice. Have you seen what they put in their mouths? To say nothing of the other half of the cycle.
- Robots can move without warning - hm, now that I'm warned, I guess they can't, now, can they?
- Do not attempt to move, manipulate, or control dangerous or hazardous materials with robot - I wasn't planning on it, but I'm kind of excited by the implication that I could. What did you have in mind?
- This is a teaching aid - way to take the fun out of something dangerous and exciting.
