Abstract: A cleaner performing autonomous traveling includes a main body, a driving unit moving the main body, a battery supplying power to the driving unit, a communication unit performing communication with a charging station to charge the battery, a sensor sensing a signal emitted from the charging station, and a controller controlling the driving unit such that the main body is docked to the charging station on the basis of the signal sensed by the sensor, wherein when the main body starts to move to dock to the charging station, the controller determines a kind of the signal sensed by the sensor and controls the driving unit such that the main body moves along a traveling path corresponding to a circle centered on a predetermined point on the basis of the determined kind of the signal.

Abstract: A moving robot includes: a main body; a traveling unit configured to rotate and move the main body; a sensing unit configured to sense position information of a specific point of a front portion of a docking device; and a controller configured to, based on sensing result of the sensing unit, determine i) whether a first condition, which is preset to be satisfied when the docking device is disposed in a front of the moving robot, is satisfied, and ii) whether a second condition, which is preset to be satisfied when the moving robot is disposed in a front of the moving robot, is satisfied, to control an operation of the traveling unit so as to satisfy the first condition and the second condition, and to move to the front so as to attempt to dock in a state where the first condition and the second condition are satisfied.
