Abstract

The invention relates to a mobile robot full-coverage path planning method, a chip and a robot, and the method comprises the following steps: S1, the robot detects an obstacle in a cleaning region, generates a map containing obstacle information, and divides the map into a plurality of sub-blocks; S2, the robot plans a cleaning path in the sub-block; and S3, the robot determines the initial sub-blocks and performs cleaning, then calculates the path cost between the sub-blocks, selects the next cleaning sub-block according to the path cost, and cycles the step until cleaning of all the sub-blocks is completed. According to the new full-coverage path planning method, the calculation complexity can be reduced, and the coverage efficiency of the robot is improved.

Description

technical field [0001] The invention relates to the field of intelligent robots, in particular to a mobile robot full-coverage path planning method, chip and robot. Background technique [0002] At present, for full-coverage robots, such as sweepers, lawn mowers, window cleaners, mine-clearing robots, etc., it is necessary to cover all places that the robot can reach with the shortest path. The full coverage method is generally a traveling salesman (NP-hard) problem, which needs to be solved, given a series of cities and the distance between each pair of cities, to solve the shortest circuit that visits each city once and returns to the starting city . When the dimension of the problem increases, the calculation time required to solve the problem will increase sharply, which causes the robot to spend more time on path planning, which affects work efficiency, and it is not so intelligent, reducing the user's efficiency. Use experience. Based on this, it is necessary to dev...
