After testing on bag day, we went over the moat and attempted to move an arm with an encoder when it became apparent the encoder had stopped functioning. After debugging the problem (same encoder, alternate RIO, etc), we tested the voltage across the PWM pins on the roboRIO and found 0V between power and ground (the two outside pins) while the RIO was plugged in.

First of all, is this a problem internal to the RIO? Secondly, could someone point me towards how the RIO handles physical shock? on the current robot, it is mounted on polycarbonate which is mounted rigidly to the frame, so there is no vibrational damping. Such a system could be implemented, but I am curious if other teams have also encountered problems with their RIOs and vibration given the rough nature of the game.
