    Abstract: A mobile robot of the present disclosure includes a first pattern emission unit configured to emit a first patterned light downward and forward from the main body on a floor of an area to be cleaned; and an image acquisition unit configured to acquire an image of first patterned light emitted by the first pattern emission unit and incident on an obstacle. A pattern is detected from the acquired image to determine an obstacle, and a cliff is detected based on at least one of a shape or a position of the pattern in the image. The mobile robot may identify a travel path that does not lead to the cliff.

    Abstract: A robot cleaner includes a controller configured to sense an obstacle with a sensing unit of the robot cleaner, and control a driving unit of the robot cleaner to move a main body of the robot cleaner forward into a first contact state in which a front end of a cleaning unit cleans a first region while in contact with the obstacle. After the first contact state, the controller controls the driving unit to move the main body according to a predetermined connecting operation into a second contact state in which the front end of the cleaning unit cleans a second region while in contact with the obstacle, the first region and the second region being arranged along an outline of the obstacle.
