Abstract

A method and apparatus for handling cargo. A cargo handling system may be positioned relative to the cargo. The cargo handling system may comprise a frame structure and an engagement system. The frame structure may be configured to change in a number of dimensions to encompass the cargo. The engagement system may be configured to engage the cargo. The number of dimensions of the frame structure may be adjusted to encompass the cargo. The cargo may be engaged with the engagement system.

First claim

What is claimed is:

1. A method for handling cargo, the method comprising:
positioning a cargo handling system relative to the cargo in which the cargo handling system comprises a frame structure and an engagement system configured to engage the cargo, wherein:
the frame structure comprises a first set of segments aligned on a first axis and a second set of segments aligned on a second axis;
the first set of segments and the second set of segments form a quadrilateral shape for the frame structure;
the first axis is substantially perpendicular to the second axis; and
the frame structure is configured to change along both the first axis and the second axis to encompass the cargo;

adjusting automatically the first set of segments along the first axis and the second set of segments along the second axis to encompass the cargo; and
engaging the cargo with the engagement system.

2. The method of claim 1 , wherein the frame structure encompasses the cargo within an interior area of the frame structure.

3. The method of claim 2 , wherein the engagement system is further configured to engage the cargo within the interior area of the frame structure when the frame structure is at least one of moved away from a ground, in a first position on the ground, in a second position over the ground, and moving towards the ground.

4. The method of claim 1 further comprising:
lifting the cargo away from a ground by an aircraft associated with the cargo handling system.

5. The method of claim 4 further comprising:
flying the aircraft to a destination with the cargo held by the cargo handling system.

6. The method of claim 5 further comprising:
releasing the cargo from the cargo handling system at the destination.

7. The method of claim 1 , wherein the adjusting step comprises:
detecting a size of an interior area of the frame structure relative to the cargo using a sensor system; and
changing the first set of segments and the second set of segments of the frame structure to encompass the cargo within the interior area of the frame structure and to allow the engagement system to engage the cargo when the cargo is located in the interior area.

8. The method of claim 1 , wherein adjusting automatically comprises changing a first dimension of the first set of segments and changing a second dimension of the second set of segments.

9. The method of claim 8 , wherein the first dimension is a first length of the first set of segments and the second dimension is a second length of the second set of segments.

10. A method for transporting cargo with aircraft, the method comprising:
positioning a cargo handling system relative to the cargo in which the cargo handling system comprises a frame structure and an engagement system, wherein:
the frame structure comprises a first set of segments aligned on a first axis and a second set of segments aligned on a second axis;
the frame structure has a quadrilateral shape;
the first axis is substantially perpendicular to the second axis;
the frame structure is configured to change along both the first axis and the second axis to encompass the cargo within an interior area of the frame structure; and
the engagement system is configured to engage the cargo within the interior area of the frame structure when the frame structure is moved away from a ground;

detecting a size of the interior area of the frame structure relative to the cargo using a sensor system;
moving the first set of segments along the first axis and moving the second set of segments along the second axis to encompass the cargo within the interior area of the frame structure and to allow the engagement system to engage the cargo when the cargo is located in the interior area;
engaging the cargo with the engagement system;
lifting the cargo away from the ground by the aircraft associated with the cargo handling system;
flying the aircraft to a destination with the cargo held by the cargo handling system; and
releasing the cargo from the cargo handling system at the destination.
