The main purpose of this thesis is to develop a small wheeled SUMO robot for use in contests. The main controller of the robot is a microcontroller PIC16F877A which uses Pulse Width Modulation (PWM) signals to drive H-Bridge circuits and control two DC motors. In this study, "actuation", "perception", and "cognition" are at the core of this robot’s functions. The perception function requires the analysis of useful messages detected by the robot’s sensors. The cognition function necessitates finding the solution for these messages and making the decision as to how to respond fittingly. The actuation functions to order the drivers to actuate some essential behaviors for the competitive scenario. These processes must be carried out by the robot autonomously.
