Steffi Tamil Mathi Journal on Mobile Applications and Technologies 2394-0239 1 1 20 23 Control Architecture, GPS (Global Positioning System), GSM (Global System for Mobile Communication), Motor, Obstacle Sensor, Robot ,Mobility, GPRS (General Packet Radio Service) This paper proposes a GSM -Mobile based Robot controller system with a PC interface. The robot can be controlled by a GSM mobile [9] in order to do customized tasks from a remote location, and which would be monitored by another remote interface like a PC interface. Robot Navigation [11] guides a mobile robot to move to a desired goal, along the planned path in an environment characterized by a terrain and a set of distinct objects (such as obstacles, milestones, waypoints and landmarks). Motion planning [2] is often designed to optimize specific performance criteria and to satisfy constraints on the robot's motion. The distinguishing feature of this paper is that, true mobility can be leveraged through the Mobile Communication Network. The robot also detects the obstacles while moving through the obstacle sensor [6]. February - April 2014 Copyright © 2014 i-manager publications.
