Abstract

The different advantageous embodiments may provide an apparatus comprising a vision system, a drilling tool, and a system controller. The vision system may be configured to generate data about a number of laser signatures on a surface of a workpiece. The drilling tool may be configured to drill a number of holes in the surface of the workpiece. The system controller may be configured to generate drilling instructions for the drilling tool using the data generated by the vision system.

First claim

What is claimed is:

1. An apparatus comprising:
a vision system configured to generate data about a number of laser signatures on a surface of a workpiece, wherein the vision system identifies the number of laser signatures on the surface of the workpiece using a camera, wherein the camera captures an image of the surface of the workpiece, and wherein the vision system uses the image to identify the number of laser signatures on the surface of the workpiece and generate the data about the number of laser signatures;
a drilling tool configured to drill a number of holes in the surface of the workpiece; and
a system controller configured to generate drilling instructions for the drilling tool using the data generated by the vision system, wherein the system controller is configured to determine whether additional laser signatures exist on the surface using the image.

2. The apparatus of claim 1 , wherein the vision system identifies the number of laser signatures on the surface of the workpiece using an infrared camera.

3. The apparatus of claim 2 , wherein the infrared camera captures an image of the surface of the workpiece, and wherein the vision system uses the image to identify the number of laser signatures on the surface of the workpiece and generate the data about the number of laser signatures.

4. The apparatus of claim 1 , wherein the data generated by the vision system is transmitted to the system controller.

5. The apparatus of claim 1 further comprising:
a mobility system configured to position the apparatus at a number of locations adjacent to the surface of the workpiece.

6. The apparatus of claim 5 , wherein the number of laser signatures are generated prior to the mobility system positioning the apparatus at the number of locations, and wherein the number of laser signatures remain on the surface of the workpiece after a laser projection is blocked from having line of sight to the surface of the workpiece.

7. The apparatus of claim 1 , wherein the number of laser signatures is at least one of a chemical reaction with the surface of the workpiece, an exposure on the surface of the workpiece, a heat signature, and a change of state of the surface of the workpiece.

8. The apparatus of claim 1 , wherein the workpiece is selected from at least one of a skin, spar, wing, fuselage, and rib.

9. The apparatus of claim 1 further comprising:
a mobile platform connected to the drilling tool and configured to position the drilling tool.

10. The apparatus of claim 9 further comprising:
an arm connected to the drilling tool and configured to move the drilling tool independently of the mobile platform.

11. The apparatus of claim 10 , wherein the system controller is configured to control the arm and the mobile platform.

12. The apparatus of claim 1 , wherein the system controller is further configured to generate drilling instructions for the drilling tool based on characteristics of the number of laser signatures.

13. The apparatus of claim 1 , wherein the system controller is further configured to generate drilling instructions for the drilling tool based on characteristics of the number of laser signatures.

14. The apparatus of claim 1 , wherein the camera comprises an infrared camera.

15. An apparatus comprising:
a vision system configured to generate data about a number of laser signatures on a surface of a workpiece, wherein the vision system identifies the number of laser signatures on the surface of the workpiece using an infrared camera, wherein the infrared camera captures an image of the surface of the workpiece, wherein the vision system uses the image to identify the number of laser signatures on the surface of the workpiece and generate the data about the number of laser signatures, wherein the number of laser signatures is at least one of a chemical reaction with the surface of the workpiece, an exposure on the surface of the workpiece, a heat signature, and a change of state of the surface of the workpiece;
a drilling tool configured to drill a number of holes in the surface of the workpiece, wherein the workpiece is selected from at least one of a skin, spar, wing, fuselage, and rib;
a system controller configured to generate drilling instructions for the drilling tool using the data generated by the vision system, wherein the data generated by the vision system is transmitted to the system controller; and
a mobility system configured to position the apparatus at a number of locations adjacent to the surface of the workpiece, wherein the number of laser signatures are generated prior to the mobility system positioning the apparatus at the number of locations, and wherein the number of laser signatures remain on the surface of the workpiece after a laser projection is blocked from having line of sight to the surface of the workpiece; and
wherein the system controller is configured to determine whether additional laser signatures exist at the number of locations using the image.

16. The apparatus of claim 9 , further comprising:
an arm connected to the drilling tool and configured to move the drilling tool independently of the mobile platform.

17. The apparatus of claim 16 , wherein the system controller is configured to control the arm and the mobile platform.
