Chain guard rules?

[Jon Stratis]

ROBOT parts shall not be made from hazardous materials, be unsafe, cause an unsafe condition, or interfere with the operation of other ROBOTS.

The concern here with chain is that it can literally detach body parts that get stuck between the chain and sprocket! And yes, this has happened at an event before. (I think there's more info in another thread somewhere, but I couldn't find it).

So, your inspector is going to try to evaluate the risk, and probably land on the side of Safety. If it's exposed, put a shield on it so you can't get a finger stuck between the chain and sprocket, at least not without really trying to.
