Abstract

A mobile robotic device with a conveyor that is configured to link up with another conveyor of a second mobile robotic device is described. In this manner, the mobile robotic devices may provide integrated, flexible conveyors and the ability to link conveyors to make an aggregate conveyor of any shape or size. Moreover, the mobile robotic device is configured to receive a conveyor from a storage unit and move the conveyor to another point within a physical space. The mobile robotic device also has the capability to rotate the conveyor, when docked, about the axis of the mobile robotic device (e.g., for sorting and other operations).

First claim

What is claimed is:

1. A first mobile robotic device comprising:
a rotating head removably docked to a first conveyor, the rotating head configured to rotate the first conveyor as a whole, in at least one direction, when the rotating head and the first conveyor are docked the first conveyor including:
a conveyor belt,
a conveyor motor configured to move the conveyor belt,
and
a connector including a protruding portion, the protruding portion adapted to engage an opening of a connector receptacle of a second conveyor connected to a second mobile robotic device;
a power module including a conveyor controller, the power module configured to supply power from an external power source to at least one of the conveyor motor and the conveyor controller when the rotating head and the first conveyor are docked;
and
a drive module coupled to the rotating head, the drive module comprising a motorized axle, a pair of motorized wheels, and a pair of stabilizing wheels, the drive module configured to move the first mobile robotic device, as a whole, in at least one direction.

2. The first mobile robotic device of claim 1 , wherein the opening of the connector receptacle is coupleable to the second conveyor of the second mobile robotic device, the protruding portion of the connector enabling the conveyor belt of the first conveyor of the first mobile robotic device to be fixed in a coplanar orientation with a second conveyor belt of the second conveyor of the second mobile robotic device.

3. The first mobile robotic device of claim 2 , wherein the power module of the first mobile robotic device is configured to transmit power, via the connector, to the connector receptacle of the second mobile robotic device, the conveyor controller configured to transmit a control signal, via the connector, to the connector receptacle of the second mobile robotic device to activate the second conveyor of the second mobile robotic device.

4. A first robotic device comprising:
a first conveyor, the first conveyor including:
a conveyor belt;
a conveyor motor coupled to at least one conveyor cylinder, the conveyor motor configured to rotate the at least one conveyor cylinder to move the conveyor belt in at least one direction; and
a connector, the connector adapted to engage with a connector receptacle of a second conveyor;
a rotating head removably docked with the first conveyor, the rotating head configured to rotate the first conveyor, as a whole, in at least one direction; and
a drive module coupled to the rotating head, the drive module configured to move the first robotic device, as a whole, in at least one direction.

5. The first robotic device of claim 4 , wherein the connector includes a protruding portion, the protruding portion adapted to engage with an opening of the connector receptacle.

6. The first robotic device of claim 5 , wherein the opening of the connector receptacle is coupled to the second conveyor of a second robotic device.

7. The first robotic device of claim 6 , wherein the protruding portion of the connector enables the conveyor belt of the first robotic device to be fixed in a coplanar orientation with a second conveyor belt of the second robotic device.

8. The first robotic device of claim 6 , further comprising:
a power module, the power module including a conveyor controller and an external power connector.

9. The first robotic device of claim 8 , wherein the external power connector is configured to interface with an external power source, and the power module is configured to supply power from the external power source to the conveyor motor.

10. The first robotic device of claim 8 , wherein the power module is configured to transmit power, via the connector, to the connector receptacle of the second robotic device.

11. The first robotic device of claim 8 , wherein the conveyor controller is configured to transmit a control signal, via the connector, to the connector receptacle of the second robotic device to activate the second conveyor of the second robotic device.

12. The first robotic device of claim 4 , wherein the rotating head includes a portion that abuts at least a portion of the first conveyor.

13. The first robotic device of claim 4 , wherein the drive module includes a motorized axle and a pair of motorized wheels.

14. A method for transporting items, comprising:
moving a first mobile robotic device to a first location comprising a conveyor holder, the first mobile robotic device comprising an independent, self-powered device;
receiving, by the first mobile robotic device, a first conveyor from the conveyor holder;
docking the first mobile robotic device with the first conveyor; and
moving the first conveyor to a second location, wherein the second location comprises at least one of a first inventory holder operable to store one or more inventory items, a first inventory station configured for operations related to one or more inventory items, or a first vehicle configured to transport of one or more inventory items.

15. The method of claim 14 , further comprising:
moving a second mobile robotic device to a third location, wherein the third location is substantially adjacent to the first conveyor, the second mobile robotic device comprising a second independent, self-powered device that is docked with a second conveyor; and
connecting the second conveyor to the first conveyor to link the first conveyor and the second conveyor together.

16. The method of claim 15 , further comprising:
receiving, by the first conveyor, one or more inventory items from the at least one of the first inventory holder, the first inventory station, or the first vehicle;
transporting, via the first conveyor, the one or more inventory items to the connected second conveyor; and
transporting, via the second conveyor, the one or more inventory items to a respective end of the second conveyor in a direction away from the first conveyor and toward at least one of a second inventory holder, a second inventory station, or a second vehicle.

17. The method of claim 14 , further comprising:
receiving, by the first conveyor, one or more inventory items from the at least one of the first inventory holder, the first inventory station or the first vehicle.

18. The method of claim 17 , further comprising:
moving, by the first mobile robotic device, the first conveyor to a third location, the third location comprising at least one of a plurality of conveyors, a plurality inventory holders, a plurality of inventory stations or a plurality of vehicles.

19. The method of claim 18 , further comprising:
sorting, by the first conveyor of the first mobile robotic device, the one or more inventory items to at least one of the plurality of conveyors, the plurality of inventory holders, the plurality of inventory stations or the plurality of vehicles.
