Controlling things through wireless communication is the need of today’s era. Here as a wireless communication we are going to use is the most commonly way of communication i.e. wireless mobile phone communication. We are going to control the robotic car using wire mobile phone which is almost possess by all the people now a day. Heart of above project is Microcontroller AT89C51. The Wireless control system is designed using DTMF Decoder IC MT8870. This double tone multiple frequency IC will decode the coming tone frequency in the Binary digit form. This binary data is unique for the key pressed from the mobile phone. The binary data is fed to the microcontroller using the interfacing of this IC to the microcontroller. On the behalf of the coming data from the IC the microcontroller perform the particular task assigned to it. After getting data from the IC the microcontroller send signal to current drivers IC’s to which the DC geared motors are attached. The DC motors will work according to the data provided to the current driver IC’s to which these motors are attached. The current driver or motor driver IC is used here is L293d. The robotic car can move in any direction. The power of the robotic car is in the back wheels and the front wheel is a caster wheel. We can control the device in two modes i.e. by using only one mobile phone which is at the circuit or by using another mobile phone which at a distance place. The devices can be controlled from anywhere in the world. The must requirement of the design system to work properly is the presence of the signal (Tower range).The concept of this system can be extended in future by deploying the technology in defense areas where we need to control the robots, vehicles in the sensitive areas where human presence is dangerous..
