Abstract

A system and method are provided for controlling a plurality of vehicles to affect positioning of a common payload. The system comprises of multiple vehicles having positioners to change the location of the common payload, where the group of vehicles form a swarm that is controlled by a driver or pilot station. Each vehicle is autonomously stabilized and guided through a swarm electronics unit, which further includes sensor, communication, and processing hardware. At the driver or pilot station, a system or a person remotely enters payload destinations, which is processed and communicated to each vehicle. The method for controlling a multi-vehicle system includes inputting the desired location of the payload and determining a series of intermediary payload waypoints. Next, these payload waypoints are used by the swarm waypoint controller to generate individual waypoints for each vehicle. A controller for each vehicle moves the vehicle to these individual waypoints.

Claims

1. A computing system configured for use in controlling a plurality of vehicles configured to affect positioning of a common payload, the computing system comprising:

a transceiver configured to receive data about at least one of said common payload and said plurality of vehicles; and

a processor, in communication with said transceiver, configured to compute a path for said common payload towards a desired payload destination, configured to use said path and a current payload state to compute a desired payload state, and configured to use said current payload state and said desired payload state to compute a respective desired state for each one of said plurality of vehicles to move said common payload along said path.

2. The computing system of claim 1, wherein said transceiver is configured to transmit said respective desired state for each one of said plurality of vehicles to a respective controller of said each one of said plurality of vehicles.

3. The computing system of claim 1, wherein said transceiver is configured to receive a vehicle state from a respective controller of each one of said plurality of vehicles.

4. The computing system of claim 1, wherein said transceiver is configured to receive information used to compute the current payload state from a payload electronics unit.

5. The computing system of claim 4 wherein the information is position information of the common payload.

6. The computing system of claim 1 configured to receive the desired payload destination from a user interface.

7. The computing system of claim 1 wherein said processor is configured to compute said path based on an interpolation between said current payload state and said desired payload destination.

8. The computing system of claim 1 wherein said processor is configured to compute said current payload state by first obtaining the position of at least one of said plurality of vehicles, and then determine the position of said common payload relative to said at least one of said plurality of vehicles.

9. The computing system of claim 1 wherein said processor is configured to compute said respective desired state for each one of said plurality of vehicles by determining a next waypoint for said each one of said plurality of vehicles, and then update a spline for position, velocity and acceleration for said each one of said plurality of vehicles.

10. The computing system of claim 1 wherein said processor is configured to compute said respective desired state for each one of said plurality of vehicles to also maintain constant relative positioning between said plurality of vehicles.

11. The computing system of claim 1 wherein the plurality of vehicles are watercraft.

12. The computing system of claim 1 wherein the plurality of vehicles are spacecraft.

13. The computing system of claim 1 wherein the plurality of vehicles are land vehicles.

15. A method performed by a computing device for use in controlling a plurality of vehicles to affect positioning of a common payload, the method comprising:

computing a path for said common payload towards a desired payload destination;

using said path and a current payload state to compute a desired payload state; and

using said current payload state and said desired payload state to compute a respective desired state for each one of said plurality of vehicles to move said common payload along said path.

16. The method of claim 15 further comprising transmitting said respective desired state for each one of said plurality of vehicles to a respective controller of said each one of said plurality of vehicles.

17. The method of claim 15 further comprising receiving a vehicle state from a respective controller of each one of said plurality of vehicles.

20. The method of claim 15 further comprising receiving the desired payload destination from a user interface.

21. The method of claim 15 further comprising computing said path based on an interpolation between said current payload state and said desired payload destination.

22. The method of claim 15 further comprising computing said current payload state by first obtaining the position of at least one of said plurality of vehicles, and then determining the position of said payload relative to said at least one of said plurality of vehicles.

23. The method of claim 15 further comprising computing said respective desired state for each one of said plurality of vehicles by determining a next waypoint for said each one of said plurality of vehicles, and then updating a spline for position, velocity and acceleration for said each one of said plurality of vehicles.

24. The method of claim 15 further comprising computing said respective desired state for each one of said plurality of vehicles to also maintain constant relative positioning between said plurality of vehicles.

25. A non-transitory computer readable medium comprising computer executable instructions for use in controlling a plurality of vehicles to affect positioning of a common payload, said computer executable instructions comprising:

computing a path for said common payload towards a desired payload destination;

using said path and a current payload state to compute a desired payload state; and

using said current payload state and said desired payload state to compute a respective desired state for each one of said plurality of vehicles to move said common payload along said path.
