DESIGN AND IMPLEMENTATION OF A MOBILE (WIRELESS) PHONE CONTROLLED ROBOT

Abstract

In modern technological innovation, robotics and artificial intelligence (AI) method are now applied to do our manual tasks. Robots are becoming common in our homes, public places, industries, entertainment, and relaxation centers hence, we need to control and monitor them for easy and suitable usage. In the research, we have not only proposed but developed a robot that can be controlled by mobile phones through which we can call for some emergency situations for the Fire brigade, Law enforcement agencies (Police, Army), National Emergency Management Agency (MENA), Area Guard so on. This mobile phone-controlled robot is powered by a 9V battery for the system circuit. Whenever the user calls the mobile phone, the call is received by auto-answer mode and as the call is ongoing, the user presses a button on his handset the tone that is generated is decoded by the DTMF decoder, and the command is passed to the pre-programmed microcontroller. The Microcontroller then processes the command signal which activates the motor driver ICs for motion. This system can also be useful in reconnaissance or surveillance and applicable anywhere the GSM network service is active. The designed system is compactable, robust, and cost affordable
