The utility arm, when resting on the ground, also rested on perfectly-positioned gas shocks. This meant that if the utility arm was down and the robot was picked up off the floor, the arm would rest on the gas shocks. The motors on the arm could overpower these shocks, taking the wheels to the floor (see Chris's note) to act as a 'stinger' when the bot was on the bridge. Yet once power was cut to the motors (at the end of the match) the gas shocks had enough force to backdrive the motors to the ground pickup position, ergo off the floor if the bot was on the bridge.

Forgot about that part... I didn't notice it while talking to them, but I definitely noticed it when I watched them triple balance on the Archimedes practice field before elims.
