Remote robot control system based on DTMF of mobile phone

In the age of ubiquitous 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.
