Abstract

A method and apparatus for transporting a payload carrying device is disclosed. The method comprises providing at least one payload carrying device, a vehicle for transporting the at least one payload carrying device, a connection device for connecting the vehicle and the at least one payload carrying device, at least one sensor device for capturing information regarding the vehicle'"'"'s surrounding environment, and a control unit for operating the connection device autonomously to connect the vehicle and the at least one payload carrying device where, once connected, the weight of the at least one payload carrying device rests directly on the floor and the vehicle autonomously transports the at least one payload carrying device to a desired location, and operating the connection device autonomously to disconnect the vehicle and the at least one payload carrying device at the desired location where the at least one payload carrying device is immobilized.

Claims

1. A method of transporting a payload carrying device, comprising:

providing at least one payload carrying device;

providing a vehicle for at least transporting the at least one payload carrying device;

providing a connection device configured with at least one of the vehicle and the at least one payload carrying device for connecting the vehicle and the at least one payload carrying device with each other; and

providing a control unit for;

operating the connection device autonomously to connect the vehicle and the at least one payload carrying device where, once connected with each other, the vehicle autonomously transports the at least one payload carrying device to a desired location, and

operating the connection device autonomously to disconnect the vehicle and the at least one payload carrying device at the desired location where, once disconnected from the vehicle, the at least one payload carrying device is immobilized;

where, when the vehicle and the at least one payload carrying device are connected with each other, the at least one payload carrying device is positioned substantially within the area defined by the vehicle and has a plurality of leg supports in contact with the floor so the at least one payload carrying device'"'"'s weight rests on the floor rather than on the vehicle when the at least one payload carrying device is being transported to the desired location.

2. The method as defined in claim 1, where the vehicle immobilizes the at least one payload carrying device when the vehicle and the at the at least one payload carrying device are disconnected at the desired location to prevent unwanted movement of the at least one payload carrying device.

3. The method as defined in claim 2, where the at least one payload carrying device includes a locking device, and the vehicle communicates a signal to the locking device to immobilize the at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected to prevent unwanted movement of the at least one payload carrying device.

4. The method as defined in claim 2, where the at least one payload carrying device includes a locking device, and the vehicle is configured to mechanically lock the locking device to immobilize at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected to prevent unwanted movement of the at least one payload carrying device.

5. The method as defined in claim 1, where a user may mobilize and manually transport the at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected from each other.

6. The method as defined in claim 1, where the vehicle travels, autonomously, to a position in which the vehicle and the at least one payload carrying device can be connected with each other before the connection device connects the vehicle and the at least one payload carrying device.

7. The method as defined in claim 1, where the at least one payload carrying device includes a plurality of wheels connected to the plurality of leg supports and are in contact with the floor when the at least one payload carrying device is being transported to the desired location.

8. The method as defined in claim 1, where the vehicle mobilizes the at least one payload carrying device for transportation when the vehicle and the payload carrying device are connected with each other.

9. The method as defined in claim 1, where the connection device is selected from the group consisting of a hook, magnet, and rod-like device.

10. An apparatus for transporting a payload carrying device, comprising:

at least one payload carrying device;

a vehicle for at least transporting the at least one payload carrying device;

a connection device configured with at least one of the vehicle and the at least one payload carrying device for connecting the vehicle and the at least one payload carrying device with each other; and

a control unit for;

operating the connection device autonomously to connect the vehicle and the at least one payload carrying the device where, once connected with each other, the vehicle is configured to autonomously transport the at least one payload carrying device to a desired location; and

operating the connection device autonomously to disconnect the vehicle and the at least one payload carrying device once at the desired location where, once disconnected from the vehicle, the at least one payload carrying device is immobilized;

where, when the vehicle and the at least one payload carrying device are connected with each other, the at least one payload carrying device is positioned substantially within the area defined by the vehicle and has a plurality of leg supports in contact with the floor so the at least one payload carrying device'"'"'s weight rests on the floor rather than on the vehicle when the at least one payload carrying device is being transported to the desired location.

11. The apparatus as defined in claim 10, where the vehicle immobilizes the at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected to prevent unwanted movement of the at least one payload carrying device.

12. The apparatus as defined in claim 11, where the at least one payload carrying device includes a locking device, and the vehicle communicates a signal to the locking device to immobilize the at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected to prevent unwanted movement of the at least one payload carrying device.

13. The apparatus as defined in claim 11, where the at least one payload carrying device includes a locking device, and the vehicle is configured to mechanically lock the locking device to immobilize at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected to prevent unwanted movement of the at least one payload carrying device.

14. The apparatus as defined in claim 10, where a user may mobilize and manually transport the at least one payload carrying device when the vehicle and the at least one payload carrying device are disconnected from each other.

15. The apparatus as defined in claim 10, where the vehicle may travel autonomously to a position in which the vehicle and the at least one payload carrying device can be connected with each other before operating the connection device to connect the vehicle and the at least one payload carrying device.

16. The apparatus as defined in claim 10, where the at least one payload carrying device includes a plurality of wheels connected to the plurality of leg supports and are in contact with the floor when the at least one payload carrying device is being transported to the desired location.

17. The apparatus as defined in claim 10, where the vehicle mobilizes the at least one payload carrying device for transportation when the vehicle and the payload carrying device are connected with each other.

18. The apparatus as defined in claim 10, where the connection device is selected from the group consisting of a hook, magnet, and rod.
