OPENTECHNICAL PUBLICATION OT-2026-000002741 Robot positioning method based on multiple layers of grid maps, and chip and laser robot Published: 2026-09-15T19:15:03.088977Z Permanent URL: https://opentechnical.org/p/OT-2026-000002741 Categories: Robotics & Automation > Robot Architectures ------------------------------------------------------------------------ ABSTRACT A robot positioning method includes: collecting, by a robot, data of laser points by using a laser sensor; obtaining multiple layers of grid maps layer by layer in order from low resolution to high resolution; traversing candidate solutions in a current layer of grid map; controlling a plurality of occupancy probability values obtained correspondingly for the data of laser points at a currently traversed candidate solution to be sequentially summed when the robot determines that the currently traversed candidate solution is a feasible solution; setting, based on a ratio of a resolution of a next layer of grid map to a resolution of the current layer of grid map, the determined feasible solution as a candidate solution of the next layer of grid map; recursively determining feasible solutions in candidate solutions of the layers of grid map in the order from low resolution to high resolution. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000002741 Published 2026-09-15T19:15:03.088977Z https://opentechnical.org/p/OT-2026-000002741
