Abstract

A method is provided for operating an autonomous ball collection vehicle over a work area. Initially, information relating to the distribution of balls in the work area is determined. Then, the vehicle is guided around the work area to collect balls in response to the determined information.

Claims

1. A method of operating an autonomous ball collection vehicle over a work area comprising the steps of:

determining information relating to the distribution of balls in the work area; and

guiding the vehicle around the work area to collect balls in response to the determined information.

2. A method as claimed in claim 1, wherein the information comprises a density pattern representing the distribution of balls throughout the work area.

3. A method as claimed in claim 1, wherein the information relating to the distribution of balls is determined prior to commencing operation of the vehicle.

4. A method as claimed in claim 1, wherein the step of guiding comprises guiding the vehicle such that it starts its operation in parts of the work area in which the distribution of balls is high.

5. A method as claimed in claim 1, wherein the step of guiding comprises guiding the vehicle such that it operates primarily in parts of the work area in which the distribution of balls is high.

6. A method as claimed in claim 1, wherein the step of guiding comprises guiding the vehicle such that it operates in parts of the work area in which the distribution of balls is high more often than it operates in parts of the work area in which the distribution of balls is low.

7. A method as claimed in claim 1, further comprising sensing the position of the vehicle in the work area during the step of guiding.

8. A method as claimed in claim 7, wherein the step of sensing comprises sensing the position of the vehicle using one of GPS, differential GPS, real-time kinematic GPS, buried transponders, laser scanners, wire guides or radio beacons.

9. A method as claimed in claim 1, wherein the information relates to a known distribution of balls in the work area.

10. A method as claimed in claim 1, wherein the information relates to an expected distribution of balls in the work area.

11. A method as claimed in claim 10, wherein the information was collected by the vehicle during previous collection operations.

12. A method as claimed in claim 1, further comprising the step of storing the information in a memory of the vehicle.

13. A method as claimed in claim 12, wherein the step of guiding comprises determining a work regime from the stored information, and guiding the vehicle in response to the determined work regime.

14. A method as claimed in claim 1, further comprising the step of storing the information in a memory that is remote from the vehicle.

15. A method as claimed in claim 14, wherein the step of guiding comprises determining a work regime from the stored information by a processor that is remote from the vehicle.

16. A method as claimed in claim 15, wherein the step of guiding further comprises transmitting the determined work regime to the vehicle for execution.

17. A method as claimed in claim 15, wherein the step of guiding further comprises executing the determined work regime by the remote processor and transmitting movement commands to the vehicle.

18. A method as claimed in claim 12, wherein the information is stored in the memory by an operator.

19. A method as claimed in claim 12, wherein the information is provided to the memory by a visual sensor.

20. A method as claimed in claim 19 wherein the visual sensor is located on the vehicle.

21. A method as claimed in claim 19 wherein the visual sensor is remote from the vehicle.

22. A computer program comprising computer code that, when executed on one or more computers, causes the computer or computers to perform the method of claim 1.

23. An apparatus comprising:

a memory for storing information relating to the distribution of balls in a work area; and

processing means for guiding a vehicle around the work area to collect balls in response to the information stored in the memory.
