The article describes the development of a new obstacle avoidance method obtained by combining the potential field method and three point comparison method to overcome the local minima limitation of the exiting potential field method. The proposed method is used to guide the robot in a partially known 2-D environment to reach the target with a collision-free path and minimum traveling distance. The performance of this proposed method was tested on a mobile robot in simulated environments with different levels of obstacles. The results obtained were encouraging.
