Cell Phone Controlled Robotic Vehicle
Introduction
The project is designed to develop a robotic vehicle that is controlled by a cell phone. DTMF commands from a phone are sent to another cell phone which is mounted on the robot. These commands are fed to a microcontroller of 8051 family to operate the vehicle movement through motor interface.

Functionality
Send commands from one cell phone to be received by another cell phone.
Mounted on the robot to receive the DTMF (Dual Tone Multi Frequency) mode commands.
Which are then decoded by a DTMF decoder.
The corresponding codes are then fed to a microcontroller.

Microcontroller are programmed to recognize those codes to operate 2nos DC motors through motor driver IC.
It commands for any direction movement as per the sent commands from sender’s mobile.
The motors are controlled using motor driver IC which is interfaced to the microcontroller.
It uses microcontroller from 8051 family and a battery for power source.

Military and Law Enforcement
Remote control vehicles are used in law enforcement and military engagements for some of the same reasons.
It can be used in the borders for disposing hidden land mines.
Remote Controlled Vehicle is used by police to detect bombs, or some chemicals, etc.
Remote controlled vehicles are used by many police department bomb-squads to defuse or detonate explosives.
