Abstract

A system is provided for use in work machines that determines the location of the work machine is able to autonomously traverse between work locations. The system further provides the ability to identify corner post positions of a desired fence and have interstitial post locations automatically generated.

Claims

1. A work machine comprising:

a body;

a computing system coupled to the body;

an implement extending from the body, the implement configured to alter the ground of the workspace in which the work machine is located;

a positioning system coupled to the body and in communication with the computing system, the positioning system providing data that is passed to the computing system such that the computing system can determine a location of the work machine and an orientation of the work machine; and

software stored in memory electrically coupled to the computing system, the software including instructions that when interpreted by the computing system perform the steps of;

receiving an indication that the work machine is located at a first position;

receiving an indication of a second position where altering of the ground is desired;

determining a path from the first position to the second position; and

issuing commands to cause movement of the machine such that the implement is positioned to alter the ground at the second position.

2. The work machine according to claim 1, wherein the software further includes instructions that cause the computing system to perform the step of recording a surface profile of the path between the first position and the second position.

3. The work machine according to claim 1, wherein the desired altering of the ground includes digging with an auger and the second position is a location where auger use is desired.

4. The work machine of claim 1, further including a display viewable by a user of the work machine, the display showing a map of a workspace and relative positioning of the work machine in the workspace.

5. The work machine according to claim 4, wherein the display includes a first representation of a first desired feature at the second position, the software receiving an indication that the first representation has been selected, the step of determining a path from the first position to the second position occurring automatically upon receipt of the indication that the first representation has been selected.

6. The work machine according to claim 1, wherein the desired altering of the ground includes the placing of a fence post and the software further causes the computing system to:

receive an indication that the first position is a first fence post location,

receive an indication that the second position is a second fence post location,

receive information regarding a surface profile of a path between the first post location and the second post location,

calculate a position of a third post based upon the first post location, the second post location, and the surface profile.

7. The work machine according to claim 6, wherein the surface profile is recorded as the machine drives from the second position to the first position.

8. The work machine of claim 6, wherein the software further causes the computing system to:

issue instructions for the work machine to autonomously maneuver from the second position to the third post position such that the implement is positioned to place a fence post at the third post position.

9. The work machine of claim 6, wherein the third position is calculated such that posts placed at the first, second, and third position form a straight line.

10. The works machine of claim 9, wherein the instructions issued by the computing system instruct the work machine to travel along the straight line when moving between the second and third location.

11. The work machine according to claim 6, wherein the software further causes the computing system to:

receive input indicating a desired distance between adjacent posts, wherein the position of the third post is calculated at least partially based upon the desired distance between adjacent posts.

12. A computer implemented system for monitoring of a work machine implement, including:

a first processing sequence that retrieves a map of a workspace;

a second processing sequence that receives data from a global positioning system device coupled to the work machine;

a third processing sequence that uses the data from the global positioning device to determine a location and orientation of the work machine;

a fourth processing sequence that retrieves data regarding an implement attached to the work machine;

a fifth processing sequence that determines the position of the implement;

a sixth processing sequence that receives identification of a first desired post location;

a seventh processing sequence that receives indication that the machine is being driven to a second desired post location;

an eighth processing sequence that records ground surface profile information about a path taken from the first desired post location to the second desired post location;

a ninth processing sequence that receives identification of the second desired post location; and

a tenth processing sequence that automatically calculates a third desired post location, the calculation utilizing the first desired post location, the second desired post location, and the ground surface profile information.

13. The system of claim 12, further including an eleventh processing sequence that displays the map data, the first desired post location, the second desired post location, and the third desired post location on a display.

14. The system of claim 12, further including a twelfth processing sequence that receives an indication that a post has been placed at the second desired post location.

15. The system of claim 14, further including a thirteenth processing sequence that produces instructions to cause the machine to autonomously proceed from the second desired post location to the third desired post location.

16. A computer implemented system for monitoring of a work machine implement, including:

a first processing sequence that retrieves a map of a workspace, the map having indications of at least one location of desired implement use;

a second processing sequence that receives data from a global positioning system device coupled to the work machine;

a third processing sequence that uses the data from the global positioning device to determine a location and orientation of the work machine;

a fourth processing sequence that retrieves data regarding an implement attached to the work machine;

a fifth processing sequence that determines the position of the implement;

a sixth processing sequence that outputs data to a display to display the map, a representation of the work machine, and the at least one location of desired implement use;

a sixth processing sequence that receives input selecting a first location of desired implement use of the at least one location of desired implement use;

a seventh processing sequence that calculates a route from the position of the work machine to the first location of desired implement use;

an eighth processing sequence that receives authorization to proceed to the first location of desired implement use; and

a ninth processing sequence that outputs instructions to cause the machine to autonomously travel to the first location of desired implement use along the calculated route.

17. The system of claim 16, wherein the input selecting the first location of desired implement use comes from the display.

18. The system of claim 17, further including a tenth processing sequence that receives an indication that the implement was used at the first location.

19. The system of claim 18, further including an eleventh processing sequence that automatically picks a second location of desired implement use of the at least one location of desired implement use.

20. The system of claim 19, wherein the eleventh processing sequence picks the second location by considering the distances to other locations of desired implement use, and considering which locations of desired implement use have already undergone implement usage.
