Abstract

A warehouse automation system adapted to improve warehouse operating productivity includes a plurality of carts for transporting products within a warehouse and a controller. The controller is adapted to associate a first one of the plurality of carts with a first person and to control the first cart to lead the first person around the warehouse. According to one advantage, the time the first person spends restocking, picking, counting, sorting, moving, and packing product into customer orders and shipments, for example, is reduced.

Claims

1. An automation system adapted to improve operating productivity within an area where products are stored, the system comprising:

a plurality of carts for transporting products within the area; and

a controller adapted to associate a first one of the plurality of carts with a first person and to control and automatically move the first cart at a controller determined speed to lead the first person around the area.

2. The system of claim 1, wherein the controller determined speed is selected from the group consisting of a speed equal to a normal pace of the first person and a speed faster than a normal pace of the first person.

3. The system of claim 1, wherein the controller is further adapted to set settings of the first cart personal to the first person and to set settings of the first cart personal to a second person different from the first person when the second person is associated with the first cart.

4. The system of claim 1, wherein the controller is further adapted to assign a task to the first person based upon an ability of the first person.

5. The system of claim 1, wherein the controller is further adapted to associate a second one of the plurality of carts with the first person at the same time that the first cart is associated with the first person.

6. The system of claim 1, wherein the controller is further adapted to associate the first cart with a second person different from the first person at the same time that the first cart is associated with the first person.

7. The system of claim 1, wherein the first cart comprises at least one receptacle for receiving a product.

8. The system of claim 1, wherein the first cart comprises a motor for propelling the first cart.

9. The system of claim 1, wherein the first cart comprises at least one of an on-screen interface and an off-screen interface for communicating information to the first person.

10. The system of claim 9, wherein the first cart comprises the on-screen interface and further wherein the on-screen interface is adapted to communicate information concerning at least one of a physical location of the first cart within the area, a physical location of certain product within the area, a current task assigned to the first person, time between various tasks, priorities in the area, and performance of the first person.

11. The system of claim 9, wherein the first cart comprises the off-screen interface and further wherein the off-screen interface comprises at least one of lighting and an audio source.

12. The system of claim 11, wherein the first cart comprises the lighting and further wherein the lighting is adapted to identify a receptacle on the first cart within which a product is to be placed or from which a product is to be retrieved.

13. The system of claim 11, wherein the first cart comprises the lighting and further wherein the lighting is adapted to differ depending upon a task assigned to the first person.

14. The system of claim 11, wherein the first cart comprises the lighting and further wherein the lighting is adapted to communicate information concerning at least one of a status of the first cart, a health of the first cart, a movement speed of the first cart, and a change in direction of the first cart.

15. The system of claim 11, wherein the first cart comprises the audio source and further wherein the audio source is adapted to communicate information concerning at least one of a status of a task assigned to the first person, a proximity of the first cart to a plurality of persons, and a status of the first cart.

16. The system of claim 1, wherein the first cart comprises a sensor for, at least in part, at least one of identifying a distance of the first person from the first cart, determining a position of the first cart within the area, and identifying an obstacle in a path of the first cart.

17. The system of claim 1 further comprising at least one workstation for processing the products.

18. The system of claim 1 further comprising a display for displaying real-time performance metrics of the first and other persons.

19. The system of claim 1 further comprising a plurality of overhead cameras adapted to (i) monitor the plurality of carts, the first person, and material handling equipment, and (ii) determine a location of each cart.

20. The system of claim 1, wherein the area comprises a warehouse.

21. A method for automating and improving operating productivity within an area where products are stored, the method comprising the steps of:

associating a first person with a first one of a plurality of carts for transporting products within the area;

determining, with a controller, a speed at which to move the first cart; and

controlling and automatically moving the first cart at the controller determined speed to lead the first person around the area.

22. The method of claim 21, wherein the controller determined speed is selected from the group consisting of a speed equal to a normal pace of the first person and a speed faster than a normal pace of the first person.

23. The method of claim 21 further comprising associating the first person with a second one of the plurality of carts at the same time that the first person is associated with the first cart.

24. The method of claim 21 further comprising associating a second person different from the first person with the first cart at the same time that the first person is associated with the first cart.

25. The method of claim 21 further comprising assigning a task to the first person based upon an ability of the first person.

26. The method of claim 21 further comprising illuminating a receptacle on the first cart to identify the receptacle within which a product is to be placed or from which a product is to be retrieved.

27. The method of claim 21 further comprising illuminating a receptacle on the first cart differently depending upon a task assigned to the first person.

28. The method of claim 21, further comprising communicating, via an audio source, information concerning at least one of a status of a task assigned to the first person, a proximity of the first cart to a plurality of persons, and a status of the first cart.

29. The method of claim 21, further comprising displaying real-time performance metrics of the first and other persons.

30. The method of claim 21, wherein the area comprises a warehouse.
