In this paper, a novel collision avoidance algorithm of a mobile robot is proposed. Virtual force field between a robot and an obstacle is formed and regulated to maintain a desired distance. To avoid obstacles on the path of a mobile robot, intelligent hybrid force control is used to regulate force field of an accurate distance between a robot and an obstacle. Since uncertainties from robot dynamics and obstacles degrade the performance of a collision avoidance task, neural network is used to compensate for uncertainties. Simulation studies of avoiding obstacles by maintaining a desired distance on the path of a wheeled mobile robot are conducted to confirm the proposed algorithm.
