Title: MOBILE ROBOT AND CONTROL METHOD THEREFOR
Abstract:
The mobile robot according to one aspect of the present invention comprises: a drive unit for moving a main body; an image obtainment unit for obtaining images around the main body; a sensor unit comprising one or more sensors for sensing obstacles during travel; a storage unit for, if the sensor unit senses an obstacle, storing location information about the sensed obstacle and location information about the mobile robot, registering, as an obstacle area in a map, an area having a predetermined size around the location of the sensed obstacle, and storing images obtained by the image obtainment unit in the obstacle area; and a control unit comprising an obstacle recognition module for sequentially recognizing attributes of the obstacle from the images obtained by the image obtainment unit in the obstacle area and determining the final attributes of the obstacle on the basis of multiple recognition results sequentially recognized, the mobile robot thus being capable of accurately recognizing the attributes of obstacles and registering/managing obstacle areas.
