Abstract: In order to improve the operation efficiency of Autonomous Mobile Robot (AMR) in complex dynamic environments, a hybrid navigation algorithm based on two-way A* algorithm for path planning and local path planning based on laser SLAM and Artificial Potential Field algorithm is proposed. The feasibility and effectiveness of the algorithm are verified by experiments, and the following conclusions are drawn: The hybrid algorithm can help the robot to plan the optimal path to the target faster and has better smoothness. The hybrid algorithm has better obstacle avoidance ability for obstacles appearing randomly on the travel path of robot, and it occupies less system resources.

Keywords: A* algorithm; Artificial Potential Field algorithm; dynamic path planning
