Study of DTMF Technology Robot (Bomb Detection Device) without Microcontroller

Abstract

Abstract We observe that the control system is designed to operate a humanoid robot, using DTMF (dual tone multiple frequency) technologies of mobile phones are used for long-range operation. The mobile phone with operator act as a transmitter in the circuit and the one attached to the robot act as a receiver, hence no additional communication devices are required in the circuit network. If any button we pressed using DTMF tone corresponding to the button pressed is near at the other end of the cell, and then the circuit will be in active mode operation. The received tone is pressed by the microcontroller with the help of the DTMF decoder. The decoder decodes the DTMF tone into its equipment binary digit and the same is sent to the microcontroller. The microcontroller is set the program to take a decision for any given input and provide the output according to input operation, then it takes the decision to drive the motor in order to drive the motors in the forward and backward direction and then left and right direction. It can move the 3600 angle direction to the motor using DTMF technology.
