The motor drives the driving gear to rotate. When the driving gear touches the ground, the trolley moves forward with the driving gear. When the driven gear touches the ground and engages with the driving gear, the driven gear will follow the rotation, and the rotation direction is opposite to the driving gear, so as to realize the reverse direction of the car.
