Abstract
The present invention relates to an apparatus and method for recognizing self-position employing a virtual map divided into directional reflex distance data and cell unit, and a computer-readable recording medium for recording a program containing the method of the invention. The apparatus for recognizing self-position in a robot system includes: a reflex distance detecting unit for outputting a designated signal to each direction obtained by equally dividing 360.degree. as designated, detecting a point where the outputted signal reaches a designated object by using the signal reflected and inputted, and based on the detection result, detecting the distance to the object in each direction; direction detecting unit for providing information of absolute direction; and, controlling unit for controlling general operation of the reflex distance detecting unit and the direction detecting unit, dividing the region on a virtual map into a cell unit to generate directional reflex distance information per cell, and recognizing the present position by comparing the directional reflex distance information of each cell with the directional reflex distance information from the present position of a detected robot.
