Disclosed are a robot, which builds a map using a surface data of a three-dimensional image, from which a dynamic obstacle is removed, and a method of building a map for the robot. The method includes sequentially acquiring first and second surface data of a route on which the robot moves; matching the first and second surface data with each other to calculate a difference between the first and second surface data; detecting a dynamic obstacle from the first and second surface data according to the difference between the first and second surface data; generating a third surface data by removing the dynamic obstacle from at least one of the first and second surface data; and matching the third surface data and any one of the first and second surface data with each other to build the map.

A method and apparatus to build a 3-dimensional grid map and a method and apparatus to control an automatic traveling apparatus using the same. In building a 3-dimensional map to discern a current location and a peripheral environment of an unmanned vehicle or a mobile robot, 2-dimensional localization and 3-dimensional image restoration are appropriately used to accurately build the 3-dimensional grid map more rapidly.

A simultaneous localization and map building (SLAM) method and medium for a moving robot is disclosed. The SLAM method includes extracting a horizontal line from an omni-directional image photographed at every position where the mobile robot reaches during a movement of the mobile robot, correcting the extracted horizontal line, to create a horizontal line image, and simultaneously executing a localization of the mobile robot and building a map for the mobile robot, using the created horizontal line image and a previously-created horizontal line image.
