Abstract: A path planning method of an intelligent robot includes: (1) dividing the operating space into a plurality of rectangular virtual regions having areas of n*m square meters; (2) controlling the intelligent robot to traverse each rectangular virtual region with bow-shaped behavior; (3) when moving in bow-shape, building a raster map with the distance information acquired by distance information sensor, angle information acquired by angle information sensor, collision information acquired by collision detection sensor and obstacle information acquired by obstacle detection sensor, and marking the pass points, obstacle points and collision points; (4) analyzing the raster map in real time to judge if the entire operating space has been fully traversed: if so, moving to step (5); otherwise, returning to step (2); (5) controlling the intelligent robot to make an alongst behavior, and marking the alongst behavior points on the raster map.
