Abstract

Systems, apparatuses and methods for mapping a shopping space are provided. A system for mapping a shopping space includes a plurality of motorized transport units, a store map database, and a central computer system. The central computer system being configured to divide the map of the shopping space into a plurality of sections, assign a unique section identifier to each of the plurality of sections in the shopping space, associate a blocked tag with each section inaccessible to the plurality of motorized transport units, associate an accessible tag with each section accessible by at least one of the plurality of motorized transport units, for each section having an accessible tag, allow an access restriction setting to be configured, and provide navigation instructions to the plurality of motorized transport units based on access restriction settings of each section of the shopping space stored.

First claim

What is claimed is:

1. A system for mapping a shopping space comprising:
a plurality of motorized transport units;
a store map database for storing a map of the shopping space; and
a central computer system coupled to the plurality of motorized transport units and the store map database, the central computer system being configured to:
divide the map of the shopping space into a plurality of sections;
assign a unique section identifier to each of the plurality of sections in the shopping space;
associate, in the store map database, a blocked tag with each unique section identifier corresponding to a section of the shopping space inaccessible to the plurality of motorized transport units;
associate, in the store map database, an accessible tag with each unique section identifier corresponding to a section of the shopping space accessible by at least one of the plurality of motorized transport units;
for each unique section identifier having an accessible tag, allow an access restriction setting to be configured for the corresponding section; and
provide navigation instructions to the plurality of motorized transport units based on access restriction settings of each section of the shopping space stored in the store map database.

2. The system of claim 1 , wherein the access restriction setting comprises a restriction based on a motorized transport unit's currently assigned task.

3. The system of claim 2 , wherein the motorized transport unit's currently assigned task comprises one or more of: lead a customer, follow a customer, carry a basket, carry a cart, carry a passenger, scan shelves, and cleanup.

4. The system of claim 1 , wherein the access restriction setting comprises a restriction based on a motorized transport unit's capability.

5. The system of claim 1 , wherein the access restriction setting comprises a restriction based on whether the motorized transport unit is assigned to a store associate or a customer.

6. The system of claim 1 , further comprising: a plurality of image sensors.

7. The system of claim 6 , wherein blocked tags and accessible tags are associated with unique section identifiers based on analyzing images captured by the plurality of image sensors.

8. The system of claim 6 , wherein the central computer system is further configured to determine whether a section of the shopping space is temporarily inaccessible to the plurality of motorized transport units based on images captured by the plurality of image sensors.

9. The system of claim 8 , wherein whether a section is temporarily inaccessible is determined based on comparing images of the section captured by the plurality of image sensor and a baseline image of the section.

10. The system of claim 1 , wherein the map of the shopping space comprises a three-dimension map.

11. A method for mapping a shopping space comprising:
dividing, by a central computer system, the map of the shopping space into a plurality of sections;
assigning a unique section identifier to each of the plurality of sections in the shopping space;
associating, in a store map database, a blocked tag with each unique section identifier corresponding to a section of the shopping space inaccessible to a plurality of motorized transport units coupled to the central computer system;
associating, in the store map database, an accessible tag with each unique section identifier corresponding to a section of the shopping space accessible by at least one of the plurality of motorized transport units;
for each unique section identifier having an accessible tag, allowing an access restriction setting to be configured for the corresponding section; and
providing navigation instructions to the plurality of motorized transport units based on access restriction settings of each section of the shopping space stored in the store map database.

12. The method of claim 11 , wherein the access restriction setting comprises a restriction based on a motorized transport unit's assigned task.

13. The method of claim 12 , wherein the motorized transport unit's assigned task comprises one or more of: lead a customer, follow a customer, carry a basket, carry a cart, carry a passenger, scan shelves, and cleanup.

14. The method of claim 11 , wherein the access restriction setting comprises a restriction based on a motorized transport unit's capability.

15. The method of claim 11 , wherein the access restriction setting comprises a restriction based on whether the motorized transport unit is assigned to a store associate or a customer.

16. The method of claim 11 , further comprising associating blocked tags and accessible tags with unique section identifiers based on analyzing images captured by a plurality of image sensors coupled to the central computer system in the shopping space.

17. The method of claim 11 , further comprising determining, by the central computer system, whether a section of the shopping space is temporarily inaccessible to a motorized transport unit based on images captured by a plurality of image sensors coupled to the central computer system in the shopping space.

18. The method of claim 17 , further comprising determining whether a section is temporarily inaccessible based on comparing images of the section captured by the plurality of image sensor and a baseline image of the section.

19. The method of claim 11 , wherein the map of the shopping space comprises a three-dimension map.

20. An apparatus for mapping a shopping space comprising:
a non-transitory storage medium storing a set of computer readable instructions;
a control circuit configured to execute the set of computer readable instructions which causes to the control circuit to:
divide the map of the shopping space into a plurality of sections;
assign a unique section identifier to each of the plurality of sections in the shopping space;

associate, in a store map database, a blocked tag with each unique section identifier corresponding to a section of the shopping space inaccessible to a plurality of motorized transport units;
associate, in the store map database, an accessible tag with each unique section identifier corresponding to a section of the shopping space accessible by at least one of the plurality of motorized transport units;
for each unique section identifier having an accessible tag, allow an access restriction setting to be configured for the corresponding section; and
provide navigation instructions to the plurality of motorized transport units based on access restriction settings of each section of the shopping space stored in the store map database.
