Remote control car steered upon motor reversal

摘要

A radio-controlled car capable of making a high-speed turn on the spot is provided. The radio-controlled car provides a controller and a car designed to run forward and turn by changing the direction of rotation of a motor. A first driving wheel is fixedly mounted on one end of a driving shaft of the car and an idly rotatable second driving wheel is mounted on the other end of the driving shaft. A gear mechanism for driving the second driving wheel includes a sun gear mounted on a shaft and planetary gears rotatable around the sun gear on the center of the shaft of the sun gear. The planetary gears are designed to alternately mesh with two gears which rotate in different directions, in accordance with a change in the direction of rotation of the motor. A controller is provided in the radio controlled car and includes a charging circuit for recharging rechargeable batteries therein without requiring a separate charger or having to remove the batteries.
