Title:
PATHFINDING COST-BASED CLEANING PATH PLANNING METHOD, CHIP, AND CLEANING ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/134483
Kind Code:
A1
Abstract:
A pathfinding cost-based cleaning path planning method, a chip, and a cleaning robot. In the cleaning path planning method, candidate entrances/exits in a reasonable navigation sequence are found, as cleaning entrance positions of corresponding sub-blocks, in different sub-blocks according to pathfinding costs in different coordinate axis directions, such that a final planned cleaning path in a cleaning area can be obtained by combining and connecting, thereby reducing the navigation path distance between different sub-blocks, shortening the time spent by a robot in path planning between room areas, reducing the computing amount, and improving cleaning effect of a mobile robot.
