Patent ID: 7933687

Claim:
A system for directing a moving object, comprising: a charging device on which a docking direction pattern is printed, such that a central point of the docking direction pattern for directing the moving object to a docking location and a power-supply terminal are arranged in a straight line; and the moving object, the moving object including: a camera for capturing an image of the docking direction pattern; a docking direction pattern extractor for extracting the docking direction pattern and its central point from the captured image; a distance-information calculator for calculating distance information from a current location to the docking location according to a ratio of the number of pixels ranging from the central point of the docking direction pattern to the edge of the docking direction pattern of the captured image to the number of pixels from the central point to the edge of the docking direction pattern captured at a reference location; an offset-information calculator for calculating the angle between the current location and the docking location; and a wheel drive for driving wheel operations of the moving object according to the offset information and the distance information.
