Abstract: The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body, a boundary signal detector which detects a boundary signal generated in a boundary area of a traveling area, and a controller which controls a traveler so that the traveler performs pattern traveling a plurality of times in the traveling area, and controls the traveler so that a traveling angle during first pattern traveling and a traveling angle during second pattern traveling are different from each other. Accordingly, when the pattern traveling is performed a plurality of times, the pattern traveling is performed at angles different from each other based on a reference axis, and it is possible to minimize an area which cannot be mowed and improve efficiency.

Abstract: A moving robot includes: a boundary signal detector configured to detect a proximity boundary signal generated in a proximity boundary area in which a portion of a first travel area and a portion of a second travel area are proximal to each other; and a controller configured to define a proximity boundary line based on the proximity boundary signal, and control the travelling unit such that the body performs a homing travel which indicates travelling along the proximity boundary line. The moving robot may be included in a system that includes boundary wires to define the first and second travel areas. The system may further include a docking unit to dock with and charge the moving robot.
