Robot path planning method and device and robot

Abstract

The invention discloses a robot path planning method and device and a robot. The path planning method comprises the following steps: acquiring an initial path; according to distance information between the initial path and a current obstacle, determining a to-be-removed part of path in the initial path and a starting point and an ending point corresponding to the part of path; removing the partial path between the starting point and the ending point of the partial path, and performing path planning again to obtain a planned first path; and performing smooth optimization processing on the first path to obtain a second path. According to the technical scheme, the problem that the robot swings and walks close to the edge of an obstacle is solved, and it is guaranteed that the robot can walk stably.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a robot path planning method, device and robot. Background technique [0002] Robot navigation is the ability of a robot to determine its own position in a frame of reference and then plan a path to a certain target location. In most domestic robot products, the robot can learn the route specified by the user (for example, the robot repeats the operation many times along the route manually set by the user) to travel. [0003] A challenge that may arise, however, is that the characteristics of the environment may change after the robot has determined its route. For example, the planned route of the robot is occupied by obstacles, or the route changes. Current robots may not be able to adjust and plan new paths in real time to accommodate these changes, for example if the path is completely blocked by obstacles. In this case, the current robot may stop, collide wit...

Problems solved by technology

[0007] The main purpose of the present invention is to disclose a robot path planning method, device, and robot to at least solve the problem of triggering the robot due to sensor noise or positioning errors when the robot is working along a path that is too close to an obstacle scene in the related art. The obstacle avoidance function causes the robot to swing and walk along the wall, etc.
