Abstract
A delivery AGV has a hybrid braking system. An emergency electrical brake shorts between motor contacts to stop the AGV quickly, but it doesn't work well to keep the AGV stopped, such as when on a hill. A mechanical parking brake is electrically actuated to lock the wheels. Both systems can be used at once for stopping the AGV.
