OBSTACLE DETECTION AND AVOIDANCE ROBOT


Abstract
Robot is a system that contains sensors, control systems, manipulators, power supplies and software all working together to perform a task. Designing, building, programming and testing a robot is a combination of physics, mechanical engineering, electrical engineering, structural engineering, mathematics and computing. In some cases biology, medicine, chemistry might also be involved.

Obstacle Detecting Robot is a machine that detects any obstacle present in its way and if found, changes its direction automatically. Sensing the obstacle and maneuvering the robot to stay on course, while constantly correcting wrong moves using feedback mechanism forms a simple yet effective closed loop system.
The system contains three IR sensors that can detect the obstacle in any direction. If the vehicle encounters the obstacle in the forward direction, the robot changes it direction to left. If there is an obstacle even in the left, it moves to right and if the robot detects an obstacle in the right direction, the vehicle stops.
