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.

An apparatus for recognizing an indoor location using an RSSI (Received Signal Strength Intensity) map, includes an environment information acquirer configured to acquire indoor environment information and store the acquired indoor environment information on a node basis; a numerical map creator configured to create a numerical map; a field intensity creator configured to create the RSSI map; a dead-reckoning sensor configured to locate an area less than several meters within which the environment information acquire is actually located to locate a more accurate location within the area; a path information producer configured to produce path information including movable potential trajectories; and an initializer configured to initialize an initialization location of one or more candidate entities and fingerprint information.

A method of creating an indoor environment map includes acquiring encoded position information by detecting revolutions of wheels when a mobile unit travels using encoders to predict a position of the mobile unit based on the encoded position information, acquiring a measured distance from the mobile unit to an object existing in a surrounding environment using the distance measuring sensor, predicting a position of the mobile unit to be moved, estimating a distance from the mobile unit to the object at the predicted position of the mobile unit, determining whether the estimated distance is matched with the measured distance, correcting the predicted position of the mobile unit to estimate a position of the mobile unit to be moved by the matching of the predicted position with the measured position, and creating the indoor environment map using the corrected position and the measured distance.

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.

Apparatus and method for recognizing position of moving object

Provided is an apparatus for detecting the tension, moving direction, and length of a connector. The detecting apparatus includes a connector including one end connected inside the movement detecting apparatus and other end disposed at an outer side of the movement detecting apparatus, a tension detector measuring a tension force applied to the connector by detecting a minute change in a parameter of the tension detector when the other end of the connector is pulled away from the movement detecting apparatus, a direction detector measuring a movement of the connector in horizontal and vertical directions in a plane substantially perpendicular to the tension so as to detect a direction of the tension force applied to the connector, and a length detector detecting a length of the connector extended from the movement detecting apparatus by the tension force applied to the connector. When the connector such as a cable is pulled, the detecting apparatus detects information about the pulling conditions of the cable. Therefore, when a user walks with a dog robot by holding the cable of the detecting apparatus attached to the dog robot, the detecting apparatus provides information about the cable-holding conditions to inform the dog robot of user's intention, so that the dog robot can follow the user according to the user's intention. Thus, automatically-movable devices such as the dog robot can be conveniently used by employing the detecting apparatus since the detecting apparatus provides information about user's intention to the devices.
