Abstract: Disclosed is a robot lawnmower including a body frame, a main wheel disposed on both sides of the body frame, a motor to drive the main wheel, a first edge blade provided in a region of the body frame corresponding to the main wheel and coupled to be rotatable with respect to the body frame by receiving a driving force of the motor, and a second edge blade disposed between the body frame and the main wheel to rotate together with the main wheel and cut a grass by a relative rotation of the first edge blade and the main wheel.

Abstract: Disclosed is a pet care robot station including: a housing including an entrance allowing a pet care robot to enter and exit, and an accommodating space to accommodate the pet care robot; a door provided in the housing to open and close the entrance; and a sterilizer provided in the accommodating space to remove foreign materials from an outer surface of the pet care robot.

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.
