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 comprises the following steps: building a grid map; expanding the grid map for an obstacle in order to determine a free area, an expansion area and an obstacle area on the grid map, wherein the obstacle area is a grid areaoccupied by the obstacle, the expansion area is adjacent to the obstacle area, and the free area is a grid area other than the expansion area and the obstacle area on the grid map; and performing path planning based on the expanded grid map, wherein in the path planning, the priority of the free area is higher than that of the expansion area. Through the adoption of the path planning method, therisk of the robot colliding with obstacles can be lowered.

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...
