Abstract

This project describes an obstacle avoidance method designed specifically for small sized mobile robot with differential driver motion capabilities. Although the project may sound an off-shelf product, in this project the mobile robot is expected to return to its original straight path after avoiding any obstacle in its path and continue moving. This mobile robot system is equipped with ultrasonic and infrared sensor to sense the obstacle in front of it. The information fetched from the sensor will be analyzed by a microcontroller (PIC16F877A) in order to deduce a logical operation on it. Unlike other commercial obstacle avoidance, this mobile robot was driven by four unit de gear motor where each of it is controlling single wheel at every edge of the platform. Plus, with its gigantic and rough wheel, the robot can operate under various types of terrain and environment. Such ability makes it special compared to other commercial obstacle avoidance in the market.
