    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 method for identifying a moving object in a three-dimensional space and a robot for implementing same is provided. The robot includes a sensing module for calculating height and position information of an object by using two or more sensing units; a movement unit for moving the robot; a map storage unit for storing a three-dimensional map including the height and position information of the object, calculated by the sensing module, in a space in which the robot is moving; and a control unit for controlling the sensing module, the movement unit, and the map storage unit, converting the height and position information of the object calculated by the sensing module into global coordinates, storing, in the three-dimensional map, the height and position information of the object converted into the global coordinates, and removing, from the three-dimensional map, a moving object among objects stored in the map storage unit.
