Abstract: The present disclosure relates to a moving robot, a control method thereof, and a moving robot system. A moving robot according to the present disclosure includes a main body, a traveling unit configured to move the main body, a communication unit configured to communicate with a terminal and a location information transmitter, and a control unit configured to set a travel area using location information based on a signal received from the location information transmitter. The control unit is configured to recognize a location of the terminal. When location information regarding a target point within the boundary, pointed by the terminal at the recognized location, is received, the control unit is configured to store the location information. Also, the control unit is configured to control a traveling unit to move in the travel area while avoiding a predetermined area comprising coordinates matching the stored location information.

Abstract: A mobile robot may include a controller configured to set a virtual boundary based on position information determined by a terminal or a position sensor in an area, and to set an area of any one side of the boundary as a traveling area. The controller may control a traveling unit so that a main body moves within the traveling area without moving outside the boundary. Accordingly, the controller may easily set the boundary using the position information, and may control traveling of the mobile robot by setting the traveling area formed by the boundary. The controller may correct a position error, may reflect information on obstacles in setting the traveling area to set a traveling area appropriate for a traveling environment of the mobile robot, and/or may easily change the set traveling area.

Abstract: A lawn mower robot has a main body, and a driving unit configured to move the main body. The lawn mower robot also has a receiver configured to receive a signal transmitted from at least one transmission device in a travel area. The lawn more robot also has a controller. The controller controls the driving unit based on a result and a prestored area map. The result is based on the signal received by the receiver, and the area map includes an arrangement position of the at least one transmission device. The controller detects a position change of the at least one transmission device based on the result and updates the area map by determining a present position of the at least one transmission device in the area map according to the position change.
