Automatic controlling of a vehicle is very essential in the recent scenario, which can become possible by implementing the dual tone multi frequency (DTMF) based obstacle avoider robot, by which any vehicle can be controlled by utiliing the mobile phone signal. This robot analyzes and make use of the unique frequencies (both low and high) provided by the carrier network to control the motions of the vehicle. The vehicle is controlled by the microcontroller, which is preprogrammed in a way to respond to the signals received from the DTMF decoder. The vehicle is equipped with pairs of sensors to avoid collisions. It is an efficient way of controlling a vehicle automatically. There will be a greater development in the fields of military and domestic application, when this technology is implied.
