where you actually meet Main Breaker
The main breaker is the robot's on switch and its last line of defence. It trips when the whole robot draws too much — usually a stalled drivetrain shoving against a wall — and once it has tripped repeatedly it starts tripping earlier and earlier. Keep a spare in the pit, because a tired main breaker looks exactly like a bad battery.
