[Joseph Smith]

I agree that it would be a good practice to always cover pinch points and exposed chains, but many times it's just not plausible with the design of the robot. However, fingers should never be anywhere near pinch points if the robot is running or parts are being moved by hand- that's common sense. Clear communication between team members working on the robot should be enforced to prevent someone from moving a mechanism or enabling the robot while someone else is working near a pinch point.
