Abstract:

DTMF technology is peerless to the present generation DTMF technology a derived the theory of Digital Signal Processing.

Beforehand Radio Frequency circuit is used for wireless controlling but it has the big deprivation that is range.

Owing to which it limits the control and has unfavorable effect on the performance of the car, Whereas the DTMF converts this deprivation of Radio Frequency circuit into dominance. It provides increased range of working und also provides better results.

This system is controlled und managed using phone in microcontroller.

The wireless communication is the remote handling operation of robot using Dual Tone Multi Frequency.

Formally, wirelessly controlled robots use radio frequency circuits that have the lack of restricted working range.

Restricted frequency range and the restricted control these of a cell phone for robot control can overcome these restrictions.

It provides the dominance of robust control raise as more as the coverage area of the service provider, no intervention with other controllers and up to 12 controllers.

• To control the robot using DTMF module using mobile.
• To implement DTMF control robotic vehicle.
