DTMF BASED UNMANNED VEHICAL

In this article, vehicle is controlled by the Robot using Dual Tone Multi Frequency (DTMF) technology. Now a days DTMF technology is most useful technique in Robotic vehicle control. It is worked on to methods digital signal processing (DSP). Wireless-control of robots uses RF circuit that has the drawbacks of limited working range and limited control. This DTMF is gives advantage over the RF; it increases the range of working and also gives good results in case of motion and direction of robot using mobile phone through micro controller. This type of wireless communication gives the remote handling operation of Robot using DTMF and with the help of the motor driver we will control vehicle directions.
