Patent abstract
A method and apparatus for reckoning a position of a moving robot using dead-reckoning and range sensing. The method includes performing dead-reckoning to determine a variation state in accordance with motion of the moving robot, calculating an absolute position of the moving robot by sensing a distance between the moving robot and at least one fixed position, predicting an optimized current position of the moving robot using the variation state and the absolute position, determining whether the optimized current position is within a specified effective area, and correcting the optimized current position in accordance with the determined result.
