DTMF decoder, motor driver, mobile, microcontroller.
In this paper, we can control the Robot using Dual Tone Multi Frequency (DTMF) technology. Basically , the paper is about a mobile controlled robot which will use the DTMF technology for the interaction with the circuit mounted phone. The robot is controlled by a mobile phone that makes a call to another mobile phone attached to the
robot.During this call the robot will performits functions according to the key pressed on the mobile phone tht is used to make a call. This is actually done with the help of DTMF. The robot percieves the tone with the help of tone stacked on the circuit. This tone is then processed by the microcontroller with the help of DTMF decoder. Microcontroller then sends this signal to the motor’s driver IC to operate the motors. Once this is done the motors then starts moving and the robot is operated.
