Mobile Robot Localization by RFID Method
This paper explores the merits of the indoor positioning system using Radio-Frequency IDentification (RFID) technology for mobile robots. The indoor positioning function by the Received Signal Strength Indicator (RSSI) and the Link Quality Indicator (LQI) method is developed first to determine the location of the robot. The RSSI and the LQI based indoor positioning system employs wireless signal intensities to build the intensity distribution map and compares the signal intensity of the transmitters obtained by the receivers to determine the location of the robot. In the end, the implementation is to use a predetermined indoor environment, which is set up beforehand to validate the RFID based indoor positioning system developed by a mobile robot.
