Dual Toned Multi-Frequency Controlled Robotic Vehicle without Micro-Controller

Abstract

The main aim of this project is to make a system of robotic vehicle which can be controlled remotely by using GSM technology. This research paper describes how to develop such system where we can control remote vehicle remotely. We can control the Robot using Dual Tone Multi Frequency (DTMF) technology. DTMF technology is most useful technique at present days. It is worked on the method of digital signal processing (DSP). Wireless-control of robots uses RF circuit that has the drawbacks of limited working range and limited control. Thus, DTMF gives advantage over the RF by increasing the range of working and gives good results in case of motion and direction of robot using mobile phone that too without using microcontroller.
