Description

technical field [0001] The invention relates to the field of robot motion control, in particular to a traction control method and system for a legged robot based on an improved artificial potential field. Background technique [0002] At present, legged robots are mainly operated by remote control, which undoubtedly reduces the working efficiency of the robot. When the operator controls the robot, the human eye is used as the visual feedback. The phenomenon of repeated action adjustments of the robot has greatly caused the operator's control fatigue, and the control efficiency is low. [0003] At present, research on autonomous walking of legged robots has been carried out. The more common path planning algorithms are A* global search algorithm and genetic algorithm. Among them, the A* search algorithm is affected by the selection of heuristic functions, and it is difficult to find the global optimal solution; The structure of the algorithm is relatively complex, and the ca...
