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: 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: 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 invention relates to a method for positioning on the basis of vision information and a robot implementing the method. The method for positioning on the basis of vision information, according to an embodiment of the present invention, comprises the steps of: generating, by a control unit of a robot, first vision information by using image information of an object sensed by controlling a vision sensing unit of a sensor module of the robot; generating, by the control unit of the robot, a vision-based candidate position by matching the first vision information with second vision information stored in a vision information storage unit of a map storage unit; and generating, by the control unit, the vision-based candidate position as the position information of the robot when there is one vision-based candidate position.

Abstract: A moving robot includes: a body defining an exterior; a traveling unit configured to move the body against a travel surface; an operation unit disposed in the body and configured to perform a predetermined operation; a tilt information acquisition sensor configured to acquire tilt information on a tilt of the travel surface; and a controller configured to, when target movement direction being preset irrespective of an inclination of the travel surface crosses an upward inclination direction of the travel surface, control a heading direction, which is a direction of a traveling force (Fh) preset to be applied by the traveling unit to the body, to be a direction between the target movement direction and the upward inclination direction based on the tilt information.

Abstract: A moving robot is provided. The moving robot includes a body, first and second driving wheels configured to move the body, first and second caster wheels installed movably, first and second sensors configured to respectively detect a rotation angle of the first caster wheel and a rotation angle of the second caster wheel with respect to a predetermined direction axis, and a controller configured to control driving of a driving wheel according to the rotation angles. The controller calculates an average rotation angle by using the rotation angles detected by the first and second sensors and controls driving of the driving wheel by using the calculated average rotation angle.
