Abstract

A system for loading and unloading containers of items from transport vehicles and moving containers of items to and from desired locations using automated robots are disclosed. The system includes one or more automated robots, a base station, and one or more vehicle-based systems. The automated robots are configured to move to, lift, and carry containers of items. The base station is configured to coordinate the movements of the automated robots. The vehicle-based systems are associated with transport vehicles and configured to communicate information about containers on the transport vehicles to the base station or automated robots. The vehicle-based systems may call the one or more automated robots to automatically load or unload the transport vehicles.

First claim

What is claimed is:

1. A system for processing containers of items, the system comprising:
one or more automated robots, the automated robots comprising:
a housing sized to allow the one or more automated robots to be positioned underneath a container of items;
a drive portion connected to a bottom portion of the housing;
a lift mechanism connected to a top portion of the housing and configured to contact an underside of the container of items;
one or more sensors, the sensors configured to identify a location of the one or more automated robots within a facility; and
a scanner configured to read a container identifier on a container;

a base station located in the facility and associated with the one or more automated robots, the base station comprising:
one or more charging stations for charging the one or more automated robots;
one or more processors configured to communicate with and instruct the one or more automated robots; and

wherein the one or more processors are configured to:
before arrival of a vehicle at a dock of the facility, receive, from a vehicle-based system on the vehicle, a vehicle identifier of the vehicle and the container identifier for the container, the container being located on the vehicle and intended for unloading at the facility;
determine an intended location for the container;
instruct one or more of the automated robots to move to a location of the container on the vehicle;
instruct the one or more of the automated robots to scan, via the scanner, a code located on the container;
receive the scanned code located on the container;
compare the receive scanned code with the container identifier received before arrival of the vehicle at the dock; and
when the scanned code matches the container identifier, instruct the one or more of the automated robots to transport the container to the determined intended location for the container.

2. The system of claim 1 , wherein the lift mechanism is configured to contact the underside of the container of items when the one or more automated robots are positioned underneath the container of items.

3. The system of claim 2 , wherein the one or more automated robots are configured to move underneath the container and to actuate the lift mechanism to lift the container off a surface, thereby allowing the one or more automated robots to move the container.

4. The system of claim 1 , wherein the container identifier includes a container type.

5. The system of claim 4 , wherein the one or more processors further configured to determine, based on the container type, a number of the one or more automated robots required to transport the container.

6. The system of claim 5 , wherein the container is a pallet, and wherein the server identifies that a plurality of automated robots are required to transport the pallet.

7. The system of claim 6 , wherein the server instructs the plurality of automated robots to move to different locations under the pallet in order to transport the pallet.

8. The system of claim 1 , wherein the one or more processors are configured to determine, in the distribution information database, the intended location for the container based on identifying, in the distribution information database, a next process for one or more items contained within the container.

9. The system of claim 8 , wherein the distribution information database includes a plurality of locations within the facility, each of the plurality of locations being associated with a process within the facility, and wherein the server is configured to identify the intended location from the plurality of locations based on the next process for one of the one or more items in the container.

10. A method for processing containers of items, the method comprising:
before arrival at a dock of a facility of a vehicle, receiving, in a server of the facility, from a vehicle-based system of the vehicle, a container identifier for a container, the container being located on the vehicle and intended to be unloaded at the facility and a vehicle identifier of the vehicle;
determining, in a distribution information database, an intended location within the facility for the container;
instructing, by the server, one or more automated robots to move to a location underneath the container on the vehicle, the one or more automated robots comprising:
a housing sized to allow the one or more automated robots to be positioned underneath a container of items;

a drive portion connected to a bottom portion of the housing;
a lift mechanism connected to a top portion of the housing and configured to contact an underside of the container of items; and
one or more sensors, configured to identify a location of the one or more automated robots within the facility;
a scanner to read a code located on a container;

scanning, via the scanner on the one or more automated robots, the container;
comparing the read code on the container with the received container identifier; and
when the read code corresponds to the received container identifier, instructing, by the server, the one or more automated robots to transport the container to the determined intended location for the container.

11. The method of claim 10 , further comprising:
moving the one or more automated robots underneath the container;
actuating the lift mechanism on the one or more automated robots underneath the container;
contacting the lift mechanism with an underside of the container of items;
lifting the container off a surface, thereby allowing the one or more automated robots to transport the container; and
moving the container to the intended location.

12. The method of claim 10 , wherein receiving the container identifier comprises receiving a container type.

13. The method of claim 12 , further comprising determining, based on the received container type, a number of the one or more automated robots required to transport the container.

14. The method of claim 13 , wherein the container is a pallet, and wherein the method comprises determining that a plurality of automated robots are required to transport the pallet.

15. The method of claim 14 , further comprising instructing the plurality of automated robots to move to different locations under the pallet in order to transport the pallet.

16. The method of claim 10 , wherein the intended location for the container is determined by the server based on identifying, in the distribution information database, a next process for one or more items contained within the container.

17. The method of claim 16 , wherein the distribution information database includes a plurality of locations within the facility, each of the plurality of locations being associated with a process within the facility, and wherein identifying the intended location for the container comprises identifying the intended location from the plurality of locations based on the next process for one of the one or more items in the container.
