A Localization Algorithm for Mobile Robots in RFID System

Abstract

This paper presents an efficient localization algorithm for an indoor mobile robot using the RFID system. The mobile robot carries a RFID reader at the bottom of the mobile robot, which reads the RFID tags on the floor to localize the mobile robot. Each RFID tag stores its own unique position which is used to calculate the position of the mobile robot. In this paper, a SLAM (simultaneously localization and mapping) algorithm is proposed to extend into RFID system for positioning and localization. Though the experiments, this algorithm has been proved to successfully achieve the mobile object position estimation and tracking in 2D range by using known RFID data.
