Absolute Position and Orientation Recognition Technology Using an RFID for Mobile Robots

Localization is one of the most important technologies of indoor service robots. The accumulated position error due to long-time driving makes it difficult to perform the location based service. In this paper, we propose a radio frequency identification (RFID) absolute positioning system that measures the position and direction of movement of the robot using only RFID information. When the robot is moving, the position error increases while the position measurement algorithm is updated, so in this paper, the position error is estimated and corrected to improve position accuracy.
