Localization system for indoor robot using RFID

Abstract

Indoor robots need accurate localization system to perform assigned task. In this paper, a localization system for indoor mobile robot using passive Radio Frequency Identification Technology (RFID) is proposed. RFID Localization technique relies on accurate estimation of the read range between the tags and the reader. The proposed system reads any three different RFID tags, which have a known location. The current location can be estimated using the Time Difference Of Arrival (TDOA) scheme. The simulation results validate the proposed system.
