The control system is disabled at the end of the match, which will in turn make the robot not drive outputs. So basically, relays will return to a non-asserted state and vfd's will pass no power.

For pneumatics, it means that single solenoid valves will return to original postion and double solenoid valves will stay in the last state.

For motors, it means they will lose power. If there is an anti-backoff mechanism in the gearbox, it will stay where it is. If there is not an anti-backoff mechanism, an arm could stay where it is is balanced or if friction is enough to counteract the force of gravity.

Note
 

I believe that pneumatics remain pressurized, even if your compressor is turned off, so an arm would remain extended. This was evident last year, when Team 852's robot always had to have its pressure system evacuated before it was unlatched from a goal. I believe that we were using double-solenoid valves.

Not to be picky, but shouldn't it be "Hey guys, I have the best idea!"

the entire concept is moot due to more recent updates, no negative points, no controlling opponent scores, none of it...
