Abstract

A central computer system identifies a mobile item container in a retail shopping facility as being abandoned. The central computer system then directs a motorized transport unit through the retail shopping facility to the abandoned mobile item container and causes that motorized transport unit to physically attach to the abandoned mobile item container. The central computer system then directs that motorized transport unit through the retail shopping facility with the attached abandoned mobile item container to a specified destination within the retail shopping facility. Abandonment can be determined as a function, at least in part, of determining that the mobile item container is both stationary and unattended for at least a predetermined amount of time. By one approach the central computer system can use different predetermined amounts of time when assessing abandonment depending upon where in the retail shopping facility the mobile item containers are located.

First claim

What is claimed is:

1. A method comprising:
by a central computer system:
identifying a mobile item container in a retail shopping facility as being abandoned;
directing, via a wireless network connection, a motorized transport unit through the retail shopping facility to the abandoned mobile item container;
causing the motorized transport unit to physically attach to the abandoned mobile item container;
directing, via a wireless network connection, the motorized transport unit through the retail shopping facility with the attached abandoned mobile item container to a specified destination within the retail shopping facility.

2. The method of claim 1 wherein the central computer system is configured to identify the mobile item container in the retail shopping facility as being abandoned by, at least in part, using video information of the retail shopping facility.

3. The method of claim 1 wherein the central computer system is configured to identify a mobile item container as being abandoned by, at least in part, determining that the mobile item container is both stationary and unattended for at least a predetermined amount of time.

4. The method of claim 3 wherein the central computer system uses different predetermined amounts of time when assessing abandonment of mobile item containers depending upon where in the retail shopping facility the mobile item containers are located.

5. The method of claim 4 wherein the central computer system uses shorter predetermined amounts of time when assessing abandonment of mobile item containers located in a low traffic area for mobile item containers than when assessing abandonment of mobile item containers located in shopping aisles.

6. The method of claim 1 wherein the central computer system determines the specified destination as a function, at least in part, of whether the abandoned mobile item container contains any items.

7. The method of claim 6 wherein the central computer system specifies an empty cart deployment area as the specified destination when the abandoned mobile item container is empty of any items.

8. The method of claim 6 wherein the central computer system specifies a cart processing area as the specified destination when the abandoned mobile item container contains any items.

9. The method of claim 8 wherein the cart processing area comprises a customer service area of the retail shopping facility.

10. A shopping facility assistance system comprising:
a plurality of motorized transport units configured to move through a retail shopping facility;
a central computer system having a network interface such that the central computer system wirelessly communicates with the plurality of motorized transport units and wherein the central computer system is configured to:
identify a mobile item container inside the retail shopping facility as being abandoned;
direct a particular one of the plurality of motorized transport units through the retail shopping facility to the abandoned mobile item container;
cause the particular one of the plurality of motorized transport units to physically attach to the abandoned mobile item container; and
direct, via a wireless network connection, the particular one of the plurality of motorized transport units through the retail shopping facility with the attached unattended mobile item container to a specified destination within the retail shopping facility.

11. The shopping facility assistance system of claim 10 wherein the mobile item container comprises a wheeled shopping cart.

12. The shopping facility assistance system of claim 10 wherein the central computer system is configured to identify the mobile item container in the shopping facility as being abandoned, at least in part, based on video information of the retail shopping facility.

13. The shopping facility assistance system of claim 12 wherein at least some of the plurality of motorized transport units include at least one external-environment sensor and wherein the central computer system is further configured to identify the mobile item container in the retail shopping facility as being abandoned, at least in part, based on external-environment sensor information provided by at least one of the plurality of motorized transport units.

14. The shopping facility assistance system of claim 10 wherein the central computer system is configured to identify a mobile item container as being abandoned as a function, at least in part, of determining that the mobile item container is both stationary and unattended for at least a predetermined amount of time.

15. The shopping facility assistance system of claim 14 wherein the central computer system uses different predetermined amounts of time when assessing abandonment of mobile item containers depending upon where in the retail shopping facility the mobile item containers are located.

16. The shopping facility assistance system of claim 15 wherein the central computer system uses shorter predetermined amounts of time when assessing abandonment of mobile item containers located in a low traffic area for mobile item containers than when assessing abandonment of mobile item containers located in shopping aisles.

17. The shopping facility assistance system of claim 10 wherein the central computer system determines the specified destination as a function, at least in part, of whether the abandoned mobile item container contains any items.

18. The shopping facility assistance system of claim 17 wherein the central computer system specifies an empty cart deployment area as the specified destination when the abandoned mobile item container is empty of any items.

19. The shopping facility assistance system of claim 17 wherein the central computer system specifies a cart processing area as the specified destination when the abandoned mobile item container contains any items.

20. The shopping facility assistance system of claim 19 wherein the cart processing area comprises a customer service area of the retail shopping facility.
