Abstract: A moving robot includes: a boundary signal detector configured to detect a proximity boundary signal generated in a proximity boundary area in which a portion of a first travel area and a portion of a second travel area are proximal to each other; and a controller configured to define a proximity boundary line based on the proximity boundary signal, and control the travelling unit such that the body performs a homing travel which indicates travelling along the proximity boundary line. The moving robot may be included in a system that includes boundary wires to define the first and second travel areas. The system may further include a docking unit to dock with and charge the moving robot.

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.

Abstract: A water purifier or other liquid dispenser may sense a height of the inlet of a container accurately through an infrared transmitter and an infrared receiver that are disposed at different positions of a water discharge module moving vertically. Additionally, in the water purifier, the water discharge module may discharge purified water at a point spaced a certain distance apart from the inlet of the container, based on infrared sensing, thereby preventing the inlet of the container from contacting the lower surface of the water discharge module.

Abstract: The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body, a boundary signal detector which detects a boundary signal generated in a boundary area of a traveling area, and a controller which controls a traveler so that the traveler performs pattern traveling a plurality of times in the traveling area, and controls the traveler so that a traveling angle during first pattern traveling and a traveling angle during second pattern traveling are different from each other. Accordingly, when the pattern traveling is performed a plurality of times, the pattern traveling is performed at angles different from each other based on a reference axis, and it is possible to minimize an area which cannot be mowed and improve efficiency.

Abstract: The present disclosure relates to an image sensor and a camera and an electronic apparatus including the same. An image sensor according to one embodiment of the present disclosure comprises a first light amount detection pixel to detect a first light amount of a first area, a first sensor pixel to output pixel data by converting light of the first area into an electric signal, a second light amount detection pixel to detect a second light amount of a second area, and a second sensor pixel to output pixel data by converting light of the second area into an electric signal, wherein a dynamic range of the first sensor pixel is different from a dynamic range of the second sensor pixel. Accordingly, a high dynamic range may be implemented within one frame.

Abstract: The present disclosure provides a moving robot including a body which forms an appearance, a traveler which moves the body with respect to a traveling surface in a traveling area, a sensing unit which acquires environment information of the traveling area, and a controller which sets a parameter tailored to the traveling area according to the environment information and performs pattern traveling of the traveling area. Accordingly, even when information on an environment in which the moving robot is installed is not obtained from a manufacture in advance, the moving robot can directly obtain information on the corresponding environment and set an optimum parameter according to the environment to increase efficiency.

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.
