Apparatus and method for correcting position of mobile robot
First Claim
Patent Images
1. An apparatus for correcting a position of a mobile robot comprising:
- a position notifying unit, installed at a predetermined position, that generates a position signal indicative of the predetermined position, wherein the position notifying unit comprises a magnet fixing station affixed to a surface perpendicular to a plane in which a mobile robot moves, the magnetic fixing station including at least one magnet which generates a magnetic field having a binary pattern uniquely identifying the predetermined position;
a position signal detector, installed at a predetermined position of the mobile robot, that detects the position signal; and
a control unit, installed at a predetermined position of the mobile robot, that corrects a position of the mobile robot on the basis of pre-stored position information corresponding to the detected position signal.

Abstract
An apparatus and a method for correcting a position of a mobile robot includes a position notifying unit, installed at a predetermined position, that generates and transmits a signal indicative of the predetermined position. The mobile robot includes a position signal detector, installed at a predetermined position of the mobile robot, that detects a signal; and a control unit, installed at a predetermined position of the mobile robot, that corrects a position of the mobile robot on the basis of pre-stored position information corresponding to the detected position signal, so that a position error that is generated when the mobile robot moves is corrected.

11. A method for correcting a position of a mobile robot that moves in a first plane, the method comprising:
-
generating, by at least one maonet included in a magnet fixing station installed at a predetermined positionin in a second plane, the second plane being perpendicular to the first plane, a position signal indicative of the predetermined position, wherein the position signal is a magnetic field having a binary pattern uniquely identifying the predetermined position; detecting the position signal; and correcting a position of the mobile robot on the basis of pre-stored position information corresponding to the detected position signal. - View Dependent Claims (12, 13, 14, 15, 16)

17. A mobile robot, comprising:
-
a position signal detector that detects a position signal, indicative of a predetermined position, and generated by a position notifier comprising a magnet fixing station that includes at least one magnet affixed to a surface perpendicular to a plane in which the mobile robot moves; and a controller that corrects a position of the mobile robot on the basis of pre-stored position information corresponding to the detected position signal, wherein the position signal detector comprises at least one magnetic sensor that detects a binary pattern in a magnetic field uniquely identifying a predetermined position, and coverts the detected binary pattern into a binary electrical signal. - View Dependent Claims (18, 19, 20)
