Abstract

A method and apparatus for automated handling a structure. A handler system comprises a plurality of towers and a plurality of end effectors coupled to the plurality of towers. Each of the plurality of end effectors is movably coupled to a tower of the plurality of towers. Each of the plurality of end effectors comprises an arm coupled to the tower and a coupling device for use in automated engagement of a corresponding fitting coupled to the structure.

First claim

What is claimed is:

1. A method for automated engagement and handling of a structure, the method comprising:
moving a handler system into a position relative to a support that is holding the structure, the handler system including a plurality of end effectors;
positioning the plurality of end effectors relative to a plurality of fittings coupled to the structure such that a coupling device of each end effector of the plurality of end effectors is positioned relative to a corresponding fitting of the plurality of fittings;
wherein a first engagement device of the coupling device of each end effector and a second engagement device of the coupling device are positioned on opposite sides of a hole in the corresponding fitting; and

engaging the plurality of fittings with the plurality of end effectors to secure the structure to the handler system
moving the handler system with the structure secured to the handler system away from the support.

2. The method of claim 1 , further comprising:
moving the handler system with the structure secured to the handler system for positioning alongside an assembly; and
positioning, by the handler system, the structure in a selected position relative to the assembly.

3. The method of claim 2 , further comprising:
joining the structure to the assembly;
disengaging the plurality of end effectors from the plurality of fittings after the structure has been joined with the assembly; and
moving the handler system away from the assembly.

4. The method of claim 1 , wherein positioning the plurality of end effectors comprises:
positioning a first end effector coupled to a first tower of the handler system relative to a first fitting of the plurality of fittings; and
positioning a second end effector coupled to the first tower of the handler system relative to a second fitting of the plurality of fittings.

5. The method of claim 4 , wherein positioning the first end effector comprises:
positioning the coupling device of the first end effector relative to the first fitting with respect to at least one of an x-axis, a y-axis, or a z-axis to thereby position the first engagement device of the coupling device and the second engagement device of the coupling device on opposite sides of a first hole in the first fitting.

6. The method of claim 5 , wherein positioning the second end effector comprises:
positioning the coupling device of the second end effector relative to the second fitting with respect to at least one of the x-axis, the y-axis, or the z-axis to thereby position the first engagement device of the coupling device and the second engagement device of the coupling device on opposite sides of a second hole in the second fitting, wherein the coupling device of the first end effector is positioned independently of the coupling device of the second end effector.

7. The method of claim 1 , wherein positioning the plurality of end effectors comprises:
positioning a first pair of end effectors coupled to a first tower of the handler system relative to a first pair of fittings from the plurality of fittings;
positioning a second pair of end effectors coupled to a second tower of the handler system relative to a second pair of fittings from the plurality of fittings; and
positioning a third pair of end effectors coupled to a third tower of the handler system relative to a third pair of fittings from the plurality of fittings.

8. The method of claim 1 , wherein engaging the plurality of fittings with the plurality of end effectors comprises:
moving a first member of the coupling device of an end effector of the plurality of end effectors relative to a base of the end effector in a direction substantially parallel to an x-axis such that a tapered end portion of the first member passes through a hole in the corresponding fitting and moves towards a channel within a second member of the coupling device; and
securing the tapered end portion of the first member within the channel of the second member to thereby engage the corresponding fitting with the first member and the second member.

9. A method for automated handling of a structure, the method comprising:
moving a handler system with the structure secured to the handler system for positioning alongside an assembly, the handler system having a plurality of end effectors engaged with a corresponding plurality of fittings coupled to the structure;
positioning, by the handler system, the structure in a selected position relative to the assembly using a laser guidance system;
joining the structure to the assembly;

disengaging the plurality of end effectors from the corresponding plurality of fittings after the structure has been joined with the assembly; and
moving the handler system away from the assembly.

10. The method of claim 9 , further comprising:
moving the handler system into a position relative to a support that is holding the structure;
positioning the plurality of end effectors relative to the corresponding plurality of fittings coupled to the structure; and
operating the plurality of end effectors to engage the corresponding plurality of fittings to thereby secure the structure to the handler system, wherein each fitting of the corresponding plurality of fittings is engaged by a corresponding end effector of the plurality of end effectors.

11. The method of claim 9 , wherein moving the handler system comprises:
moving a platform structure to which a plurality of towers are coupled, the plurality of end effectors being coupled to the plurality of towers,
wherein the plurality of end effectors includes a pair of end effectors coupled to each tower of the plurality of towers; and
wherein each end effector of the pair of end effectors is independently capable of being positioned to engage a fitting of the corresponding plurality of fittings coupled to the structure.

12. A handler system for handling a structure, the handler system comprising:
a plurality of towers; and
a plurality of end effectors coupled to the plurality of towers, wherein each of the plurality of end effectors is movably coupled to a corresponding tower of the plurality of towers and comprises:
an arm coupled to the tower; and
a coupling device for use in automated engagement of a corresponding fitting coupled to the structure, wherein the coupling device comprises:
a base;
a first engagement device movably coupled to the base; and
a second engagement device fixedly coupled to the base.

13. The handler system of claim 12 , further comprising:
a platform structure, wherein each of the plurality of towers is movably coupled to the platform structure; and
a mobile system coupled to the platform structure to move the platform structure on a floor.

14. The handler system of claim 12 , further comprising:
a control system at least partially housed in a control unit coupled to the corresponding tower to which to a pair of end effectors is coupled, wherein the control system controls a positioning of the pair of end effectors and of the coupling device of each end effector of the pair of end effectors relative to the corresponding fitting coupled to the structure.

15. The handler system of claim 12 , wherein each end effector of the plurality of end effectors comprises:
a support system configured to move the base relative to the first engagement device with at least one of at least one degree of translational freedom or at least one degree of rotational freedom.

16. The handler system of claim 12 , wherein the first engagement device includes a first member having a tapered end portion and the se
