Path Following Mobile Robot using Passive RFID Tags in Indoor Environment

Abstract

A Radio Frequency Identification (RFID) based tracking system becomes very important to our future world of pervasive computing, where information is all around us. Location finding is one of the most needed information for emerging and future applications. RFID tags may provide a new way of giving location information to mobile robot. Because of its small passive communication circuit and without an energy source, RFID tags can be embedded almost anywhere with any object. The Ultra High Frequency (UHF) RFID tags can stores location information which supply to any reader that is within a proximity range which can be up to approximately 15 meters. The robot senses all RFID tags using tags IDs which fall into reader’s recognition area. Then the robot use Received Signal Strength Indicator (RSSI) technique to find the distance of RFID tags which is plotted in the ground. In this paper, we design a path which is build by putting passive RFID tags in serial format on the ground. After plotting all the tags, the mobile robot first tracking and navigating those tags, so that the next robots could follow through the path. In each divider of path breaker we use read/write RFID tags to avoid future problem. The RFID-based path following mobile robot which automatically navigate and moves source to destination accordingly in indoor environments without using directional antenna.
