    Abstract: A plurality of autonomous cleaners and a control method thereof are disclosed. The present disclosure relates to a plurality of autonomous cleaners including a first cleaner and a second cleaner, wherein the first cleaner receives an obstacle map for a cleaning area from the second cleaner, performs calibration on the received obstacle map based on the coordinate system of its own prestored obstacle map, and transmits transformation data corresponding to the calibration to the second cleaner, and the second cleaner applies the transformation data to its own obstacle map, and recognizes the position coordinate corresponding to a wireless signal received from the first cleaner to generate a cleaning command.

    Abstract: A mobile robot and a controlling method thereof of the present disclosure includes: a main body which travels in an area; a tool mounted at the main body to assist n cleaning; a holder onto which the tool is held; and a charging stand which supplies operating power to move the main body, wherein when the tool becomes separated from the holder, upon receiving a tool separation signal from the charging stand, the main body moves to a position of the tool so that the tool may be mounted at the main body. Accordingly, when the tool becomes separated, the mobile robot may detect a position of a user based on a map, and may move upon recognizing a user having the tool, without requiring the user to move, thereby enabling the user to mount the tool and designate an operation in a convenient manner.

    Abstract: A method for controlling a plurality of robot cleaners comprise to perform cleaning of a first area and a second area by a first robot cleaner and a second robot cleaner sequentially, respectively. The first area and the second area are included in a plurality of areas which are divided from a region to be cleaned. The second robot cleaner is controlled to start cleaning of the first area after the first robot cleaner has performed cleaning of the first area more than a predetermined standard.

    Abstract: Disclosed is a robot cleaner including a main body forming an outer shape, a water tank including a water level sensor and storing water, a pair of rotary mops to which a cleaning cloth is attached, and that moves the main body while rotating in contact with a floor, a drive motor rotating the pair of rotary mops, a nozzle supplying water from the water tank to the cleaning cloth of the rotary mop, and a controller periodically determining an abnormality in water supply to convert to a wet mop mode or to a dry mop mode to proceed with cleaning. Therefore, in the present disclosure, the sensor may be provided in the water tank to detect the water shortage in the water tank for supplying water to the rotary mop, thereby determining whether to change modes by the robot cleaner itself.
