A cleaning device including a suction motor; a suction head including a suction port; a rotatable brush inside the suction head; a brush motor; a pressure sensor; a memory storing coefficient tables including coefficients of a hyperplane equation for determining a type of surface to be cleaned; and a controller. The controller is configured to, in a first state with the suction head separated from the surface, select a reference coefficient table corresponding to a first suction pressure and a first load of the brush motor, in a second state with the suction head in contact with the surface, identify a type of the surface based on a second suction pressure, a second load of the brush motor, and the reference coefficient table, and adjust an output of the suction motor and/or the brush motor based on the identified type of the surface to be cleaned.

Cleaning device and control method thereof

A robot or a cleaning robot is provided. The robot includes a housing forming an external appearance of the robot, a cover configured to be coupled at a lowermost part of the housing, and at least one or more sensor structures positioned between the housing and the cover. The sensor structure includes a conductive plate and a sensor electrode on the conductive plate.

Robot and method for controlling the same

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.

Pet care system, pet care robot and method for controlling pet care robot

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.

Robot lawnmower

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.
