As mentioned above... a switch that you are proposing would allow an electrical load to be supplied/managed through something that is not controlled by the ROBOT.

You could ask Q and A to make sure.
But I am a humble inspector and if I saw it I would consider it to be illegal unless you get some official opinion that would be contrary to that.

i would encourage you to think of a way to feed your manipulator by purely physical and not electrical means at the beginning of the match.

sorry
During game play it would be controlled by the FMS, the switch can only be engaged manually and it is momentary. But I can see how and why an inspector would deny it.

The tubes (not hyper-inflated) did load manually during practice but the at the Alamo regional they were inflated to the point they were ready to pop.

Perhaps the spike (that controls the motor with the switches in the normally open position) is shorting the motor, that would make the motors hard to turn. Of course it could be the 100:1 gearing ;o). or maybe I can dis-engage the gears somehow. Making a new gripper is not an attractive option.
