Abstract
Aspects of the present invention provide an RFID system for safely controlling an auto guided vehicle, an automated robot or other moving object ('AGV'). The system may include a plurality of radio frequency identification ('RFID') tags, and each may store a unique identification in a first memory location, a position in a second memory location and/or an instruction in a third memory location. An AGV having an RFID transceiver or antenna and a computer with a non-transitory computer-readable storage medium containing a predetermined table may read one or more of the memory locations. The table comprises a plurality of data elements with certain data elements associated with particular RFID tags. The AGV safely determines its location upon matching the one or more memory locations read with one or more data elements, or triggers a fault upon failing to match. The AGV may also predict the next RFID tag.
