As the present world is running behind ROBOTICS and Modern Electronics, this study gives a brief theory and practical implementation of an electronic system, so called as a ROBOT. This book is very useful for the beginners of electronics especially 'THE ROBOTICS'. A detailed explanation has been given with respect to the Design which involves the components like micro-controllers, Serial and Parallel communication Ports, Analog to Digital Converters, Actuators like Brushless DC Motors, Stepper Motors, the driving IC's required in driving the above said actuators and so on...this study makes every beginner of robotics to easily understand the components and the methodology of embedding the required components in an order to make the system more effective. In brief, two models have been developed, one with DC Motors and the other with Stepper Motors as the actuators. And a comparative study have been carried out by making these two models to trace some predefined tracks or paths and the results are displaced which is the major part of this study.
