This paper describes a wireless robot which performs the necessary actions by receiving a set of instructions in the form a DTMF frequency. In this project we can control the robot directions like forward, backward, left and right by sending call from the mobile and also performs operations like metal detection and video camera surveillance. This project mainly consists of 2 sections, one is mobile unit and the other one is robot unit. The GSM modem which is fixed at the robot receives the dtmf frequency sent by the mobile and gives the instructions to the microcontroller to control the robot directions. In this project, we interface 8051 microcontroller with GSM Module. The protocol used for the communication between controller and GSM modem is UART (Universal Asynchronous Receiver-Transmitter). This system continuously checks for message to take the decision for controlling the robot.
