Abstract: Aiming at the problem that artificial potential field algorithm is applied to the path planning of intelligent lawn mowing robot, it introduces the fuzzy control algorithm, establishes the level of repulsive potential field, adjusts the robot to avoid obstacles timely and effectively, and realizes the function of path planning. Matlab simulation results show that the fuzzy improved artificial potential field algorithm can effectively control the intelligent lawn mowing robot in real time to avoid obstacles in time, start mowing the lawn accurately, and work to the target end point, and the planned path is relatively smooth, which proves the effectiveness and feasibility of the algorithm.
