RF wireless controlled ROBOT
0 reviews / Add Your Review
Availability: In stock
The project is designed to control the ROBOT by using a RF technology for remote operation using an transmitter and receiver. The speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if the voltage across motor terminal is varied, then the speed can also be varied.

DESCRIPTION

The project is designed to control the ROBOT by using a RF technology for remote operation using an transmitter and receiver. The speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if the voltage across motor terminal is varied, then the speed can also be varied.

This project uses the above principle to control the speed of the motor by varying the duty cycle of the pulse applied to it (popularly known as PWM control). At the transmitting end using push buttons,  commands are sent to the receiver to control the movement of the robot and make it move forward /  backward and besides.  An RF transmitter acts as a  remote control that has the advantage of adequate range (up to 200 meters) with proper antenna. The receiver decodes the commands before feeding it to another DC motor via motor driver IC for necessary work. The average voltage given or the average current flowing through the motor will change depending on the duty cycle (ON and OFF time of the pulses), so the speed of the motor will change accordingly. The motor driver IC is interfaced to the decoder ic for receiving PWM signals and delivering desired output for  speed control of the DC motor.

 

Furthermore, the project can be enhanced by using power electronic devices such as IGBTs to achieve speed control higher capacity industrial motors.
