Abstract: A mobile robot may include a controller configured to set a virtual boundary based on position information determined by a terminal or a position sensor in an area, and to set an area of any one side of the boundary as a traveling area. The controller may control a traveling unit so that a main body moves within the traveling area without moving outside the boundary. Accordingly, the controller may easily set the boundary using the position information, and may control traveling of the mobile robot by setting the traveling area formed by the boundary. The controller may correct a position error, may reflect information on obstacles in setting the traveling area to set a traveling area appropriate for a traveling environment of the mobile robot, and/or may easily change the set traveling area.

Abstract: In a water purifier or other liquid dispenser, a sensor configured to transmit and receive a distance measuring signal is installed in a water discharge module moving vertically or disposed at the front of a main body, to sense a height of the inlet of a container accurately without a no-response duration of the sensor. Additionally, in the water purifier, the water discharge module discharges purified water at a point spaced a certain distance apart from the inlet of the container, to prevent the inlet of the container from contacting the lower surface of the water discharge module.
