    Abstract: An apparatus for recognizing a position of a moving object includes a sensor information collector to collect sensor information associated with movement of the moving object, a camera to capture a front image based on the movement of the moving object, and a GPS receiver configured to receive a GPS position of the moving object. Further, the apparatus includes a location recognizer to display N number of particles, each of which indicates a candidate position of the moving object, in a certain region about a GPS location of the moving object on a map. The location recognizer then updates a location of the particles based on the movement of the moving object, and progressively reduces number of particles on the basis of accuracy of the position-updated particles, thereby recognizing the position of the moving object.

    Abstract: Disclosed herein are an apparatus and method for generating a topological map for navigation of a robot. The method for generating a topological map for navigation of a robot, performed by the apparatus for building the topological map for the navigation of the robot, includes calculating the physical size of a single pixel on a metric map of a space in which a mobile robot is to navigate, extracting the physical coordinates of the pixel on the metric map, building node data and edge data for the navigation of the mobile robot using the physical coordinates, and generating a topological map for the navigation of the mobile robot based on the built node data and the built edge data.
