An RF transmitter module is connected to the transmitter unit with the aid of an encoder device. The pushbuttons are connected to the microcontroller as input switches. The commands are sent by the push buttons to reach the receiver to control the movement of the robot, either in forward, backward left or right directions.
An RF receiver is connected to the receiving end with the aid of a decoder device. The two motors are interconnected to the microcontroller through an exciter IC of the motor in which they are used to operate or to change the directions of the robotic vehicle.
