Sensors on thearm?

Has anyone tried to use sensors to make sure that you dont violate the 84" rule. Anyone have any recomendations?

First thought would be make it so you CAN’T break the rules.

Mechanical stops > Programming Stops… and this is coming from the team’s programmer.

Yeah, I would have to agree. It is much easier, and more reliable, to simply make a mechanical stop, rather than programming it in.
