This Paper describes about developing a robotic prototype of unmanned land vehicle. The Robot Uses an ATmega8 Microcontroller to control the motors of locomotion. The robot can be controlled from a remote area as it uses GSM based cellular phones to send and receive signals. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call which is recognized by the DTMF decoder connected to the cellular phone at robot end which decodes the signal and passes it on to the Microcontroller which in turn controls the motors of locomotion through L293D Motor Driver. While this idea is can be easily implemented in the Electric vehicles as they run on motors, it might be a challenge to incorporate this technology in the vehicles that run on petroleum based fuels.
