ROBOT CLEANER AND CONTROLLING METHOD THEREOF

PURPOSE: Rooms are compartmentalized and the topological map is out written. The cleaning can be proceed to the room unit or the per sector in which user wants the topological map to the basis. CONSTITUTION: A robot cleaner(1) comprises an obstacle detection unit(100), a control unit(200), and a display unit. The obstacle detection unit detects the obstacle and outputs the obstacle information. The control unit extracts the feature point from the obstacle information. The control unit is created the topological map in which a plurality of rooms is classified to the basis. The control unit is composed of a characteristic point abstraction module(210), a sector setting module(220), and a topological map generation module(230). The characteristic point abstraction module extracts a plurality of feature points from the obstacle information. By using feature points, it compartmentalizes the cleaning area into a plurality of sectors and the sector calibration module establishes. The topological map generation module is created the topological map by using a plurality of sectors. The display unit indicates the topological map.
