概要

This paper presents RFID based neighboring objects positioning system using geometrical relations. For the purpose, a direction and distance sensing RFID system is developed. While a robot moves, the robot senses the direction to a target transponder using the difference of received signal strengths from a dual directional antenna and the distance between neighboring transponders, and the robot and the transponders. Then the transponders' positions can be estimated using the distances, bearings to the target, and moving intervals of the robot based on minimum mean squared error algorithm. The experiment results using an in-house simulator based on the distance and direction sensing data in real environment using the developed RFID system show that the positions of the transponders can be successfully estimated.
