Abstract
Fast innovation speed in the hardware and software technologies in the field of embedded robot systems, it becomes more and more necessary to develop applications based on methodologies, which take to account the easiness of future modifications, updates and improvements. According to these requirements, mobile robot is designed to convey basic knowledge about the basic block technologies that make up a robot. This mobile robot can function as autonomous mobile robot as well as wireless mobile robot. In autonomous mode with the help of infrared light sensor input robot follows wooden maze. In wireless mode, robot movement is decided according to the dual tone multiple frequencies (DTMF) generated by mobile phone. This paper also includes interfacing issues of complex programmable logic devices (CPLD) with sensors, actuators, power supply & communicating devices. The paper is mainly focused on designing flexible mobile robot & various issues related to interfacing various modules with CPLD.
