MOBILE ROBOT AND METHOD FOR CONTROLLING SAME

WIPO Patent Application WO/2018/139796

A1

A robot cleaner according to one embodiment of the present invention comprises: a traveling unit for moving a main body; an image acquisition unit for acquiring an image around the main body; a sensor unit including at least one sensor for sensing an obstacle during the movement; a storage unit for storing position information of a detected obstacle and position information of a mobile robot when the sensor unit detects the obstacle, registering an area having a predetermined size around a position of the detected obstacle as an obstacle area in a map, and storing the image acquired by the image acquisition unit in the obstacle area; an obstacle recognition module for recognizing sequentially attributes of the obstacles with respect to images acquired by the image acquisition unit in the obstacle area, on the basis of data learned by a machine learning, and determining a final attribute of the obstacle on the basis of the sequentially recognized plurality of recognition results; and a control unit for determining properties of a plurality of obstacles by the obstacle recognition module when detecting a constraint state in which all possible travel routes are blocked due to the plurality of obstacles, and controlling the traveling unit to move one of the plurality of obstacles.
