Dual Tone Multiple Frequency (DTMF) Mobile Control Robot

In the age of existing systems it is important to be able to control robots everywhere. Although many methods to remotely control robots have been devised, the methods have the problems such as the need for special devices or software to control the robots. This paper suggests a method for robotic control using the DTMF tone generated when the user pushes mobile phone keypad buttons o when connected with a remote mobile robot. This paper summarizes a the feasibility of implementing Dual-Tone, Multi-Frequency (DTMF) as an alternative mean of robotic communication to Radio Frequency (RF). Our robot is controlled by a cell phone, through this we can make our robot communicate on a large scale over a large distance even from different cities. This robot can also be used to reach the places where humans cannot reach such as small tunnels, etc.
