DTMF Controlled Robot Using Arduino

Abstract

Abstract: In this paper, we will control the Robotic car using the Dual Tone Multi Frequency (DTMF) technology. DTMF technology is useful technique in the present days. It works on the methods digital signal processing. Wireless control robots will use RF circuit that has many drawbacks like limited working range and limited control. This DTMF will have advantage over the RF; it will increases the range of working and also gives the good results in case of motion and direction of robot using the mobile phone through a micro controller. This type of wireless communication gives an remote handling operation of Robot using the DTMF. An robot is a electro-mechanical machine which has been guided by the computer, Mobile phone or programming, and is able to do the tasks by its own. The Robot Institute of America had defined A robot is an reprogrammable multifunctional manipulator -designed to move material parts, tools , specialized device through a variable programmed motions for an performance of many variety of tasks. Conventionally, wireless controlled robots will uses the RF circuits, which has the drawbacks of limited working of range & frequency range, use of mobile phones can be overcomed by this limitation. Keywords: DTMF, arduino, motor driver, mobile phone.
