Abstract

Claims (42)

1. A method of in-space assembly comprising:

providing a first roll of spooled high strength composite (HSC) boom, a robotic arm, and a printhead disposed at about an end of said robotic arm, said first roll of spooled high strength composite boom feedingly coupled to said printhead;

positioning said robotic arm;

dispensing from said first roll of spooled high strength composite boom a first length of high strength composite boom;

positioning again said robotic arm;

dispensing a second length of high strength composite boom from a second roll of spooled high strength composite boom;

joining by said printhead said first length of high strength composite boom to said second length of high strength composite boom; and

repeating said step of positioning to said step of joining until a desired structure is assembled in part or in whole;

wherein said printhead comprises:

a top clamp;

a bottom clamp; and

mechanical fasteners configured to join said first length of high strength composite boom and said second length of high strength composite boom; and

wherein said robotic arm comprises three points of rotation.

2. The method of in-space assembly of claim 1 , wherein said step of positioning comprises positioning by bending and twisting said robotic arm.

3. The method of in-space assembly of claim 1 , wherein said step of joining comprises delivering by said printhead one or more mechanical fasteners through at least a portion of said first and second lengths of high strength composite boom.

4. The method of in-space assembly of claim 1 , wherein said step of joining comprises delivering by said printhead one or more of a blind rivet or a grommet mechanical fastener through at least a portion of said first and second lengths of high strength composite material.

5. The method of in-space assembly of claim 1 , wherein said step of joining comprises delivering by said printhead one or more of lever tooth rivets through at least a portion of the first and second lengths of high strength composite material.

6. The method of in-space assembly of claim 1 , wherein said step of joining comprises delivering by said printhead one or more of linear spring rivets through at least a portion of the first and second lengths of high strength composite material.

7. The method of in-space assembly of claim 1 , wherein said step of joining comprises delivering by said printhead one or more of push rivets with extending teeth.

8. The method of in-space assembly of claim 1 , wherein said step of dispensing comprises dispensing from said first roll of spooled high strength composite boom said first length of high strength composite boom comprising a plurality of holes along a longitudinal axis of said first length of said high strength composite boom and said step of joining comprises joining by said printhead said first length of high strength composite boom to said second length of high strength composite boom by inserting a mechanical fastener into aligned holes of two or more high strength composite booms.

9. A method, comprising:

coupling a printhead relative to a robotic arm;

dispensing first and second lengths of high strength composite boom from one or more supplies of high strength composite boom toward the printhead;

manipulating the robotic arm to position the printhead relative to the first and second lengths of high strength composite boom; and

joining by the printhead the first and second lengths of high strength composite boom to form a coupled boom structure;

wherein said printhead comprises:

a lever arm,

rivets, and

a cutting mechanism, and

wherein:

said rivets are configured to join said first and second lengths of high strength composite boom; and

said cutting mechanism is configured to cut said first and second lengths of high strength composite boom.

10. The method of claim 9 , wherein dispensing the first and second lengths of high strength composite boom comprises dispensing the first and second lengths of high strength composite boom from respective individual first and second rolls of high strength composite boom.

11. The method of claim 9 , wherein joining by the printhead includes coupling the first and second lengths of high strength composite boom in overlapping arrangement.

12. The method of claim 9 , further including advancing at least one of the first and second lengths of high strength composite boom with an advancing member integrated with the printhead.

13. The method of claim 12 , wherein advancing the at least one of the first and second lengths of high strength composite boom includes moving the at least one of the first and second lengths of high strength composite boom along one or more feedstock rolls.

14. The method of claim 9 , further including cutting the at least one of the first and second lengths of high strength composite boom with said cutting mechanism.

15. The method of claim 9 , wherein joining by the printhead includes connecting the first and second lengths of high strength composite boom with said rivets by said lever arm in said printhead.

16. The method of claim 15 , further including sequentially feeding the printhead with one or more rivets.

17. The method of claim 9 , wherein joining by the printhead further comprises fusing the first and second lengths of high strength composite boom by thermobonding.

18. The method of claim 1 , comprising coupling the first and second rolls of spooled high strength composite boom to a printhead frame.

19. The method of claim 10 , comprising coupling the individual first and second rolls of high strength composite boom to a printhead frame.
