Abstract/Summary: In this paper, we present a low computational algorithm that implements obstacle avoidance behaviour for wheeled mobile robots. The algorithm exploits one ultrasonic sensor and a set of proximity switches to reach autonomous navigation that may be applied in mobile robotics exploring tasks. The algorithm has been applied on an experimental prototype that uses low cost – low computational components and in a simulation environment. Series of experiments proved the efficiency of the algorithm. Future work targets enhancement of the method to path / target tracking tasks.
