Al and I are not really disagreeing here. Excessive drivetrain friction will drag the battery voltage down, but that alone will only cause a momentary loss of control. It shouldn't cause a complete loss of communication. If things are properly wired, the control system is designed to shut down the motors before the voltage gets too low to maintain its operation. A robot that reboots when you try to turn on the ground, but works okay when up on blocks, has more than one thing wrong with it.
