Abstract

Autonomous carriers or totes that include vacuum units are provided. As the totes move or are moved through a warehouse carrying products, they collect debris. The debris can be analyzed at the tote, and actions can be performed based upon the analysis.

First claim

What is claimed is:

1. A system for removing debris from a product storage facility, the system comprising:
a product storage facility, the product storage facility including a plurality of product storage units that hold products, the products being of multiple types;
a plurality of pathways that are disposed throughout the storage facility, the pathways extending between or around the product storage units;
a first autonomous carrier that is configured to traverse selected ones of the plurality of pathways, the first autonomous carrier configured to carry products to and from selected ones of the product storage units, the first autonomous carrier including multiple storage spaces for holding different types of the products, the first autonomous carrier also including a vacuum unit, the vacuum unit being configured to remove debris from the pathways as the first autonomous carrier traverses the pathways as it carries the products.

2. The system of claim 1 wherein the vacuum unit of the first autonomous carrier is further configured to analyze characteristics of the debris, determine an action to take based upon the analysis, and take the action, the action being one or more of sending an alert message to an employee of the product storage facility, moving selected one of the products within the facility, or sending a control signal to control an environmental control apparatus within the facility.

3. The system of claim 1 , further comprising a second autonomous carrier, the second autonomous carrier being of the same dimensions and form factor as the first autonomous carrier.

4. The system of claim 3 , wherein the second autonomous carrier includes a second vacuum unit and does not include any space for carrying products.

5. The system of claim 1 , wherein the first autonomous carrier includes a propulsion unit to cause the first autonomous carrier to traverse the pathways.

6. The system of claim 1 , wherein the characteristics of the debris include the smoke content of the debris, the mold content of the debris, the ozone content of the debris, or the bacteria content of the debris.

7. The system of claim 1 , wherein at least some of the pathways include conveyor belts.

8. The system of claim 1 , wherein the pathways include portions of a floor.

9. The system of claim 1 , wherein the pathways included an elevated mezzanine and transport rail structure.

10. The system of claim 1 , wherein the first autonomous carrier includes a sensor, the sensor is configured to obtain an environmental characteristic, the environment characteristic being a temperature, a pressure, or a humidity, wherein the vacuum unit determines whether the sensed characteristic is within a predetermined acceptable range, and when the predetermined characteristic is not within the predetermined acceptable range, alert the employee of the product storage facility.

11. A method for removing debris from a product storage facility, the method comprising:
providing a product storage facility, the product storage facility including a plurality of product storage units that hold products, the products being of multiple types;
providing a plurality of pathways that are disposed throughout the storage facility, the pathways extending between or around the product storage units;
providing a first autonomous carrier that is configured to traverse the plurality of pathways, the first autonomous carrier configured to carry products to and from selected ones of the product storage units, the first autonomous carrier including multiple storage spaces for holding different types of the products, the first autonomous carrier also including a vacuum unit, the vacuum unit being configured to remove debris from the pathways as the first autonomous carrier traverses the pathways as it carries the products.

12. The method of claim 11 , further comprising at the vacuum unit of the first autonomous carrier, analyzing characteristics of the debris, determining an action to take based upon the analysis, and taking the action, the action being one or more of sending an alert message to an employee of the product storage facility, moving selected one of the products within the facility, or sending a control signal to control an environmental control apparatus within the facility.

13. The method of claim 11 , further comprising providing a second autonomous carrier, the second autonomous carrier being of the same dimensions and form factor as the first autonomous carrier.

14. The method of claim 13 , wherein the second autonomous carrier includes a second vacuum unit and does not include any space for carrying products.

15. The method of claim 11 , wherein the first autonomous carrier includes a propulsion unit to cause the first autonomous carrier to traverse the pathways.

16. The method of claim 11 , wherein the characteristics of the debris include the smoke content of the debris, the mold content of the debris, the ozone content of the debris, or the bacteria content of the debris.

17. The method of claim 11 , wherein at least some of the pathways include conveyor belts.

18. The method of claim 11 , wherein the pathways include portions of a floor.

19. The method of claim 11 , wherein the pathways included an elevated mezzanine and transport rail structure.

20. The method of claim 11 , wherein the first autonomous carrier includes a sensor, the sensor is configured to obtain an environmental characteristic, the environment characteristic being a temperature, a pressure, or a humidity, wherein the vacuum unit determines whether the sensed characteristic is within a predetermined acceptable range, and when the predetermined characteristic is not within the predetermined acceptable range, alert the employee of the product storage facility.
