Are you hearing any buzzing noise while this condition is taking place? That would be an indication that the circuit breakers are rapidly resetting due to the high current temperature inside the breaker. In a case like this, the first thing to do is raise the robot off the floor and see if it drives normally and all electrical is OK. If that works check for loose wiring on the supply side of the speed controllers. If all looks OK then watch the low battery light on the operator interface to see if you are drawing so much current that the robot side is resetting. Multi motor, linked drive systems are notorious for high current draws, use an amp probe to find out how much current is actually being drawn by each speed controller.
Let us know what you find.
