Abstract

The present invention relates to systems, methods, and devices for using RFID-tagged items for omnichannel shopping and automatically reading and locating those items. Robots for automated RFID reading are disclosed. The present invention discloses Webrooming 2.0 (WR2.0) which will offer shoppers new views and tools. WR2.0 offers shoppers a bird'"'"'s eye view of equivalent items in local retail stores. WR2.0 tools empower shoppers with preemptive purchasing power: the ability to redirect their online purchases from any online web store to a local retail store.

Claims

1. ) An inventory locating system comprising:

a plurality of RFID tags attached to retail items;

a high gain antenna attached to a platform;

means for the RFID tags to respond to a radio frequency interrogation signal from the antenna;

positioning means for autonomous positioning of the antenna in a scan pattern;

platform locating means for determining the position of the antenna relative to remotely positioned reference points;

tag locating means for determining the location of the RFID tags relative to the reference points;

reading means for reading a unique item identifier from each of the plurality of RFID tags;

product search means for a web-based product search;

and means for relating the unique item identifiers from the plurality of RFID tags to the web-based product search.

2. ) The autonomous positioning of claim 1 further comprising platform velocities in excess of 6 feet per second.

3. ) The scan pattern of claim 1 further comprising a sequence of vantage points along a line.

4. ) The scan pattern of claim 1 further comprising a sequence of vantage points along an arc.

5. ) The scan pattern of claim 1 further comprising vertical movements between vantage points.

6. ) The web-based product search of claim 1 further comprising the use of a graphical user interface.

7. ) A mobile RFID tag-scanning platform comprised of:

sensing means to sense remote reference points;

control means to control the platform to instantaneous positions to form a scan pattern using data from the sensing means;

collision avoidance means to avoid collisions with obstacles;

antenna means attached to the platform for forming radio waves into a primary lobe that extends along an instantaneous vector from the platform;

means to remotely energize and collect identifiers from RFID tags that are attached to retail items and located along the vector;

means to store the identifiers with reference to the instantaneous positions and instantaneous vectors;

means to transmit the stored identifiers to a remote server that relates the identifiers to a shopper'"'"'s web searches.

8. ) The RFID tag-scanning platform of claim 7 further comprising controlled movement of the platform at a rate of speed greater than 6 feet per second.

9. ) The RFID tag-scanning platform of claim 7 further comprising a map.

10. ) The RFID tag-scanning platform of claim 7 further comprising operation in a dark room.

11. ) The RFID tag-scanning platform of claim 7 further comprising means to sense ground effect during flight over retail displays.

12. ) The antenna means of claim 7 further comprising more than one antenna.

13. ) The antenna means of claim 7 further comprising a weight of less than four ounces.

14. ) The reference to identifiers of claim 7 further comprising time-synchronized collected identifier data and stored estimates of platform position and attitude.

15. ) The mobile RFID tag-scanning platform of claim 7 further comprising a pitch control loop that is stabilized by a microelectromechanical (MEMS) accelerometer.

16. ) A system for finding desired retail items comprising:

a graphical user interface (GUI) for shopping for the retail items;

interest expression means for a shopper using the GUI to express interest in an item to a recommendation engine;

the items having at least one product identifier;

scanning means for automatically scanning retail store inventories for the presence and location of RFID tags;

relating means for relating at least one of the scanned items'"'"' identifiers to an item of interest;

ranking means for ranking the related items using relational criteria;

indicating means for indicating the top ranked items to the shopper.

17. ) The interest expression means of claim 16 further comprising means for collecting HTML that describes an item.

18. ) The system of claim 16 further comprising means for the shopper to express readiness to purchase.

19. ) The ranking means of claim 16 further comprising means for comparing price, delivery speed, and quality.

20. ) The location of RFID tags of claim 16 further comprising Cartesian coordinates.
