摘要： 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.

摘要： The present disclosure relates to a moving robot and a control method of a moving robot. The moving robot moves to a target point by setting at least one transit point in a movement path along which the moving robot starts from a current point to move a target point based on a map. Accordingly, the movement path can be easily set according a position of a boundary line or an obstacle, the movement path can be set to a shortest distance, and thus, the moving robot can rapidly move to the target point. Moreover, even when a position error is generated while the moving robot moves, the position error can be easily corrected, and even when the moving robot cannot travel due to an obstacle, the transit point is changed so that the moving robot can easily move.

摘要： The present disclosure provides a moving robot includes 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 the traveler so that the traveler performs pattern traveling in the traveling area, and when there is obstacle in the traveling area, searches for a non-traveling area due to the obstacle and controls the traveler so that the traveler continuously performs traveling of the non-traveling area. Accordingly, in a case where there is an obstacle in the traveling area when the pattern traveling is performed, continuous traveling is performed by changing a length of the pattern traveling, and thus, it is possible to complete the traveling in the traveling area without stopping the traveling and manually moving the moving robot. Therefore, it is possible to improve battery efficiency and reduce a time of a user and a cost.

摘要： 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 pattern traveling in the traveler, reads the boundary signal during the pattern traveling to determine whether or not a situation is a traveling impossible situation, and searches for whether or not there is a non-traveling area according to a determination result to control the traveler. Accordingly, when an abnormal termination situation occurs while pattern traveling is performed, the abnormal termination situation is determined to perform continuous traveling, and thus, a continuous lawn mowing control can be provided with respect to one target area.
