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: 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.

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.
