Components
UHF Tags
Tags are placed on all items in the store that are for sale. The tag stores information that is tracked by readers and antennas within the RFID robot.
RFID Readers
Transmit and receive modulated signals, complying with country regulations, in order to detect UHF passive tags.
RFID Antennas
Antennas are typically on the RFID robot’s sides with beams to detect tags and amplify the readers’ signals to improve tag detection and position accuracy.
How it works
The system used for item localisation in a retail store involves RFID tags that are read by two RFID readers, each connected to 4 antennas at each side of the robot.
When the waves from the reader reach and activate a tag, the latter sends back a signal which encodes an Electronic Product Code (EPC) that uniquely identifies the item.
The signal is detected by the emitting antenna and the reader decodes the signal to get the EPC, and transmits this information along with the strength of the signal received to the robot’s computer using a Low-Level Reader Protocol (LLRP).

The signal is detected by the emitting antenna and the reader decodes the signal to get the EPC, and transmits this information along with the strength of the signal received to the robot’s computer using a Low-Level Reader Protocol (LLRP).
The computer estimates the distance of the tag with respect to the antenna based on the signal strength, i.e. the stronger the signal the closer the tag and the other way around.
As the robot keeps moving the same tag can be detected multiple times and combining the estimated distances a more accurate position can be calculated.
