Abstract

A method includes receiving first information indicative of a location of a perimeter of a worksite surface, and receiving second information indicative of compaction requirements specific to the worksite surface. The method also includes generating a compaction plan based at least partly on the first and second information. Such a compaction plan includes a travel path for a compaction machine. In such a method, the travel path is substantially within the perimeter of the worksite surface. The method also includes causing at least part of the travel path to be displayed via a control interface of the compaction machine. The method further includes receiving an input indicative of approval of the travel path, and controlling operation of the compaction machine on the worksite surface, in accordance with the compaction plan, based at least partly on receiving the input.

First claim

What is claimed is:

1. A method, comprising:
receiving, from a machine, first data indicative of a first perimeter of a work surface at a worksite;
generating, based at least in part on the first perimeter, a first plan including a first travel path of the machine across the work surface, the first travel path being substantially within the first perimeter;
causing a first indication of the first perimeter to be presented on a display of the machine;
receiving, from the machine, second data indicative of a modification to the first perimeter;
determining, based at least in part on the second data, a second perimeter of the work surface at the worksite;
generating, based at least in part on the second perimeter, a second plan including a second travel path of the machine across the work surface, the second travel path being substantially within the second perimeter; and
causing a second indication of the second perimeter to be presented on the display of the machine.

2. The method of claim 1 , further comprising receiving third data indicative of one or more characteristics associated with at least one of the work surface or the machine, wherein:
the second plan is generated based at least in part on the one or more characteristics; and
the one or more characteristics are associated with an avoidance zone located substantially within the second perimeter.

3. The method of claim 1 , wherein:
the first indication is presented on the display at a first instance in time;
the second indication is presented on the display at a second instance in time after the first instance in time, and
the second data is received via the display during the first instance in time.

4. The method of claim 3 , wherein at the second instance in time a third indication of at least part of the first perimeter is displayed while the second perimeter is displayed, further comprising receiving a fourth indication indicative of an acceptance of the second perimeter.

5. The method of claim 1 , further comprising:
receiving third data indicative of a modification to the first travel path; and
generating the second plan based at least in part on the third data such that the second travel path includes the modification to the first travel path.

6. The method of claim 1 , wherein the machine comprises a compaction machine having a rotating drum configured to act on the work surface, and at least one of the first plan or the second plan indicates at least one of:
a vibration frequency of the rotating drum,
a vibration amplitude of the rotating drum, or
a speed of the machine along the second travel path.

7. The method of claim 6 , further comprising:
receiving third data indicative of a density of a portion of the worksite; and
determining, based at least in part on the third data, at least one of:
the vibration frequency of the rotating drum,
the vibration amplitude of the rotating drum, or
the speed of the machine along the second travel path.

8. A system, comprising:
at least one processor; and
one or more non-transitory computer-readable media store computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising:
receiving first data indicative of a work surface at a worksite;
determining, based at least in part on the first data, at least one of:
a first travel path of a machine across the work surface, or
a first boundary corresponding to the work surface, the first travel path being substantially within the first boundary,

causing the at least one of the first travel path or the first boundary to be displayed via a display of an electronic device operably connected to the at least one processor;
receiving second data representing a modification to the at least one of the first travel path or the first boundary displayed via the display;
determining, based at least in part on the second data, at least one of a second travel path of the machine across the work surface different from the first travel path, or a second boundary corresponding to the work surface and different from the first boundary; and
causing the at least one of the second travel path or the second boundary to be displayed via the display of the electronic device operably connected to the at least one processor.

9. The system of claim 8 , the acts further comprising:
causing a request for approval to be displayed via the display, the request corresponding to the at least one of the first travel path or the first boundary displayed via the display;
receiving, based on the request, a response denying approval of the at least one of the first travel path or the first boundary; and
determining the at least one of the second travel path or the second boundary based at least in part on the response.

10. The system of claim 8 , the acts further comprising:
causing a request for approval to be displayed via the display, the request corresponding to the at least one of the second travel path or the second boundary displayed via the display;
receiving, based on the request, a response denying approval of the at least one of the second travel path or the second boundary; and
causing the machine to perform an operation at least one of along the second travel path or at least partly within the second boundary.

11. The system of claim 8 , wherein the second data is received from one of:
a first mobile electronic device disposed within the machine;
a second mobile electronic device disposed at the worksite and outside of the machine;
a server disposed remote from the worksite; or
a processor of the machine and configured to control an operation of the machine.

12. The system of claim 8 , wherein the at least one of the first travel path or the first boundary is displayed in unison with the at least one of the second travel path of the second boundary.

13. The system of claim 8 , wherein the machine comprises a compaction machine having a rotating drum configured to act on the work surface.

14. The system of claim 8 , the acts further comprising:
causing third data indicative of operations performable by the machine along the second travel path to be displayed via the display;
receiving fourth data indicative of an input associated with the operations;
causing the machine to perform the operations along the second travel path.

15. A machine, comprising:
a frame;
a component supported by the frame and moveable relative to the frame, wherein the component is configured to act on a work surface of a worksite at which the machine is disposed;
at least one processor programmed to control operation of the machine at the worksite; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising:
receiving first data indicative of a first boundary of the work surface,
receiving second data indicative of a requested modification to the first boundary,
determining, based at least in part on the second data, a second boundary of the work surface different from the first boundary,
determining, based at least in part on the second boundary, a plan for the machine at the worksite, the plan including a travel path of the machine across the work surface at the worksite, and
causing the machine to perform an operation indicated in the plan, using the component, as the machine traverses the travel path.

16. The machine of claim 15 , further comprising a display, the acts further comprisin
