Localization of Unknown Placed RFID Tags Using Nomadic Robots

摘要

Self-localization of the mobile robot using RFID system generally requires a lookup table which relates the ID of each tag with its position. However, it is tedious for a human worker to manually build the table. This paper proposes a method to automatically build the lookup table by a simple mobile robot without global position measurement function. Given the small number of RFID tags with their accurate position data, the method successfully build the lookup table for many other RFID tags whose position is unknown in advance.
