And successfully used it for mobile robot path planning in the uknown complexenvironment. Simulation results demonstrate that the proposed method performs path planning very well, overcomes the drawbacks of the conventional potential field methods, and has good practicality.Keywords：Mobile robot; Potential field method; Anti-collision; Path planning
