Abstract
A mobile robot includes a travel drive unit configured to move a main body, an image acquisition unit configured to acquire an image of surroundings of the main body, a sensor unit having one or more sensors configured to sense an object during the movement of the main body, a storage configured to, when the sensor unit senses an object, store position information of the sensed object and position information of the mobile robot, register an area having a predetermined size around a position of the sensed object as an object area in a map, and store the image acquired by the image acquisition unit in the object area, and a controller having an object recognition module configured to recognize the object sequentially with respect to images acquired by the image acquisition unit in the object area, and determine a final attribute of the object based on a plurality of recognition results of the sequential recognition.
