Today, many industries are using various technology due to their high level of performance and reliability. The “real time obstacle avoidance” deals with detection and avoidance of various obstacle found in an environment. Obstacle avoidance may be divided into two parts, obstacle detection and avoidance control. For obstacle detection and avoidance, requires the integration of many sensors according to their task. Some sensing devices used for obstacle detection are infrared sensor and ultrasonic sensor. It has an infrared sensor which are used to sense the obstacle coming in between the path. It will move in particular direction and avoid the obstacle which is coming in it's path.
