RF CONTROLLED ROBOTIC VEHICLE WITH LASER BEAM

ARRANGEMENT

ABSTRACT

The project is designed to control a robotic vehicle by using a RF technology for

remote operation. A low power laser light is interfaced for demonstrating the possibilities

of destroying a distant object by its beam. An 8051 series of microcontroller is used for

the desired operation.

At the transmitting end using push buttons, commands are sent to the receiver to

control the movement of the robot either to move forward, backward and left or right etc.

At the receiving end two motors are interfaced to the microcontroller where they are used

for the movement of the vehicle. The RF transmitter acts as a RF remote control that has

the advantage of adequate range (up to 200 meters) with proper antenna, while the

receiver decodes before feeding it to another microcontroller to drive DC motors via

motor driver IC for necessary work. A laser pen is mounted on the robot body and its

operation is carried out from the microcontroller output through appropriate signal from

the transmitting end. The laser light used is just for demonstration purpose and not a

powerful one.

Further the project can be enhanced using DTMF technology. Using this

technology we can control the robotic vehicle by using cell phone. This technology has

an advantage over long communication range as compared to RF technology.
