Abstract
An autonomous mobile robot is configured to move across a floor area in accordance with a floor covering strategy and includes: based on a topological map of the floor area, designating a location of a current cell that is bounded by a primary boundary; executing a series of double strokes into and within the current cell, while mapping obstructive objects within the current cell onto an obstacle map; from the obstacle map, determining a secondary boundary of the current cell that encloses an area of the current cell covered by the executed double strokes, and distinguishes between secondary boundary portions thereof at which an obstructive object is located, and secondary boundary portions thereof at which no obstructive object is located; and adding the determined secondary boundary to the topological map of the floor area.
