Abstract: A method for changing the path plan of a mobile robot is provided to search for interconnection points by setting the maximum rectangles and then select candidate areas, so that a path is selected. An operational area of a mobile robot is set(120). The operational area is divided into a plurality of rectangles, which overlap with the contour of the operation area as much as possible(140). A connection graph representing the connection relationship of the rectangles is created(165). The intersection points between the rectangles and the contour of the operation area are created. A source point and a destination point are received, the rectangles having the source point and the destination point are searched, and the shortest path from the rectangle having the source point to the rectangle having the destination point is searched(230). A candidate area including the rectangles is selected. The path from the source point to the destination point includes only contact points so that the shortest path is selected.
