Document Type and Number:
WIPO Patent Application WO/2019/139273
Kind Code:
A1
Abstract:
A robotic vacuum cleaner of the present invention comprises: a main body including a drive unit for moving the cleaner; an obstacle detection sensor disposed in the main body so as to detect an obstacle; a tilt measurement sensor for obtaining tilt information of the main body; a storage unit for storing a cleaning map produced on the basis of danger zones including the zone where an obstacle is located; and a control unit for allowing the cleaner to perform cleaning while the main body moves and avoids the danger zones contained in the cleaning map, wherein the control unit determines whether the main body can pass through an obstacle on the basis of the tilt information of the main body, and when the obstacle is determined as an obstacle which restricts the travel of the main body, records the zone in which the obstacle is located as the danger zone on the cleaning map.
