Abstract

The invention relates to the technical field of robot path planning, and discloses a path planning method, a robot and a device with a storage function. The path planning method includes: constructing a grid map; performing expansion processing on the grid map for obstacles, so as to determine a free area, an expanded area and an obstacle area on the grid map, wherein the obstacle area is a grid occupied by an obstacle area, the expansion area is adjacent to the obstacle area, and the free area is the other grid area of ​​the grid map except the expansion area and the obstacle area; path planning is performed based on the expanded grid map; wherein, in path planning , the priority of free regions is higher than that of inflated regions. In the above manner, the present invention can reduce the risk of the robot colliding with obstacles.

Description

technical field [0001] The invention relates to the technical field of robot path planning, in particular to a path planning method, a robot and a device with a storage function. Background technique [0002] At present, the algorithm applied to robot path planning has the problem that the planned path is too close to obstacles, which makes it easy for the robot to collide with obstacles when traveling along the planned path, resulting in damage to the robot. Contents of the invention [0003] In view of this, the technical problem mainly solved by the present invention is to provide a path planning method, a robot and a device with a storage function, which can reduce the risk of the robot colliding with obstacles. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a path planning method. The path planning method includes: constructing a grid map; performing expansion processing on the grid map for...
