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.

Abstract: The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body with respect to a traveling surface in a traveling area, a sensing unit which acquires environment information of the traveling area, and a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area. Accordingly, even when information on an environment in which the moving robot is installed is not obtained from a manufacture in advance, the moving robot can directly obtain information on the corresponding environment and set an optimum parameter according to the environment to increase efficiency.
