Abstract: A pet care system includes a mobile robot comprising a first communication circuit configured to transmit a search signal through a first communication method and a second communication circuit configured to transmit event occurrence information through a second communication method different from the first communication method. The system includes a wearable device including a sensor configured to transmit a response signal through the first communication method in response to the search signal. The system includes a station comprising an operation dispenser configured to perform a predetermined operation based on the reception of the event occurrence information. The mobile robot further comprises a processor configured to determine a moving direction of the mobile robot based on the response signal received from the wearable device.

Abstract: A mobile robot and a method of controlling the same are provided, and more specifically, a technology of automatically generating a map of a lawn working area by a lawn mower robot. The mobile robot includes one or more tags configured to receive a signal from one or more beacons, a vision sensor configured to distinguish and recognize a first area and a second area on a travelling path of the mobile robot and acquire position information of a boundary line between the first area and the second area, and at least one processor configured to determine position coordinates of the mobile robot based on pre-stored position information of the one or more beacons, determine position coordinates of the boundary line based on the determined position coordinates of the mobile robot and the acquired position information of the boundary line, and generate a map of the first area while travelling along the determined position coordinates of the boundary line.
