{{warningBox warningText="CAUTION: Before powering the motors, ensure they rotate in the same direction on each side. If the wiring between the motors and the Sabertooth was done correctly, the motors on each side of the robot should rotate in the same direction.

5

If you are at all uncertain, it is safest to remove the sprockets and test the motors. If they rotate in opposite directions, the wiring to the Sabertooth needs to be corrected."/}}
