Sorry to say it is. The battery can only supply so much when discharged and the controller does not know this. Once the motors draw to much and pull the voltage down under something like 6 volts the controller dies and leaves the robot in a loop of rebooting. Thats why charged batteries are key to fixing this problem.

I have seen this to much at competitions. You can tell when this happens by looking at the lights on the side of the controller. If power blinks on and off like some one is turning the power on and off then the controller has crashed. This happens since once the controller crashes it restarts (since the voltage goes back up) but once it turns on it see RC and boots back into auto mode which then crashes the controller again since it tries to draw power again.
