Abstract

The invention discloses a path planning method and device for a robot, and the method comprises the steps: carrying out the global path planning based on a path map in a moving range of the robot, and obtaining a global path of the robot from a current position to a target position; performing local path planning based on the global path and the current position of the robot to obtain a local path; recording information of a local path on a path map; and performing global path planning based on the path map with the recorded information so as to update the global path. The problem that the matching degree of the global planning path and the local planning path is too small in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of path planning, in particular to a path planning method and device for a robot. Background technique [0002] At present, the planning algorithms of mobile robots mainly involve global planning and local planning algorithms. The global planning generates the global path of the robot motion, and the local planning generates the local trajectory to realize the specific motion of the robot, including tracking and obstacle avoidance. However, in general, global planning and local planning are relatively independent, which will cause the problem that the global planning path and the local planning path match too little, causing the robot to sway. SUMMARY OF THE INVENTION [0003] The present application provides a path planning method and device for a robot to solve the problem that the global planning path and the local planning path match too little in the prior art. [0004] In order to solve the...
