The main goal of this project is to provide with mbed microcontroller a mobile robot wheels, any curve tracer after been drawn and sent from a GUI in a PC via a wireless serial link (Bluetooth) and moving with all autonomy, managing its speed, direction and incorporating a collision detection system and obstacle avoidance. In addition, the system can communicate information such as temperature, the distance to the obstacle in front of him and the automatic/manuel mode with LCD indicator as it can transmit all these information to the user's interface to be displayed on the computer screen and can thus control the state of the system in real time. The purpose of this work is to design, adjust, produce and edit the various constituent elements of the robot. The project aims to study this robotic system, the description of its main constituents, and its hardware realization on a PCB and software in C language and Guide IDE.
