Abstract:
1. A method of detecting a position of an object using an autonomous moving object, the method comprising: receiving a user selection of a displayed object, the user selection operable to locate the displayed object from among a list of objects displayed on a display unit in a first view mode: calculating a position of the autonomous moving object using a first radio frequency identification (RFID) tag installed at a position in a predetermined space; storing, by a user input unit, information describing the object in a second RFID tag included in the object, wherein the information describing the object is input by a user during a registration mode; sensing the second RFID tag included in the object while the autonomous moving object is moving relative to the object; determining the position of the object as the position of the autonomous moving object calculated at a point of time when the second RFID tag is sensed; and displaying, on the display unit in a second view mode, the stored information describing the object at a position next to the displayed object on the display unit based on the user selection, wherein the user input unit and the display unit are disposed in the moving object, and wherein the determining the position of the object comprises matching RFID coordinates with odometry coordinates, the odometry coordinates comprising a position along an X-axis, a position along a Y-axis, and a rotation angle of θ at a point in time when the RFID coordinates are obtained from the first RFID tag.
