During the NYC FTC Championship last Saturday, in two of the matches our robots NXT brick froze, so we lost control of the robot. At the end of the match, the brick would not react to any button presses; we had to remove the battery to bring it back to life. Some of the other teams had the same problems, too - and it never happened to us before in the home practice, in qualifiers or other championship.

The field technical adviser suggested that the cause may be static buildup: a static discharge can cause voltage jump in the wiring leading to NXT. He suggested adding a grounding wire to the robot.

Anyone else experienced similar problems? Any suggestions?
