Abstract: Avoidance of Obstacle is one of the most significant aspects of autonomous mobile robots. This task is composed by two phases. First, the robot must detect obstacles in the environment with its sensors. After that , it must select an appropriate movement to go through the environment without colliding. In this work, ultrasonic sensors are adopted to implement a real-time obstacle avoidance system for robots with wheels, so that the robot can constantly detect surroundings, avoid obstacles, and move toward the target area. Secondly, three ultrasonic sensors installed on the wheeled robot were used to detect large sized obstacles and to obtain distance information between the robot and the obstacle.
