Abstract

Cell-based space systems with nested-ring structures that interlock and can change configuration to support a mission are disclosed. The cells may self-assemble into a larger structure to carry out a mission. Multiple rotatable rings may be included in a cell, with a payload/control section in the center. The rings may provide power and/or data to trams that move about the rails. Trams may interlock with other cells, carry sensors or other devices, etc. Cells may be stowed in a cell stack that is deployable. Such cell-based systems may have various applications in space, on Earth, other celestial bodies, and underwater.

Claims (73)

1 . A movable tram, comprising:

retaining members configured to engage with a tram retaining section of a rail to keep the movable tram operably connected to a ring of a cell;

control electronics configured to control operation of the movable tram; and

a mechanical conveyance mechanism that contacts the tram retaining section of the rail and facilitates movement of the tram along the rail, wherein

the movable tram is configured to move along at least a portion of the ring of the cell, as well as:

(a) connect to at least one other cell, at least one other tram of another cell, or both,

(b) provide power, data, fuel, heat, or any combination thereof, to at least one other cell,

(c) act as a support structure that holds external components that can be articulated, or any combination of (a), (b), and (c).

2 . The movable tram of claim 1 , wherein the mechanical conveyance mechanism comprises: wheels.

3 . The movable tram of claim 1 , wherein the movable tram is configured to:

connect to at least one structure.

4 . The movable tram of claim 1 , further comprising:

a linking mechanism that is configured to linking operations with linking members of other trams, with other structures, or both.

5 . The movable tram of claim 4 , wherein the linking mechanism comprises an electromagnet configured to engage with magnets of rings, trams, or both.

6 . The movable tram of claim 4 , wherein the linking mechanism comprises a layered interface comprising hardware and software that provides visual pose estimation for docking, testing of signals and information to be passed between trams, and security against cyber threats.

7 . The movable tram of claim 4 , wherein the linking mechanism is motorized and comprises a portion of a hinge joint, a pivot joint, a ball and socket joint, an ellipsoid in socket joint, a saddle joint, plane joint, a mechanical and magnetic interlock, or a spring-loaded ball and groove joint.

8 . The movable tram of claim 1 , further comprising:

at least one nozzle configured to expel a propellant gas; and

a local propellant tank configured to supply the at least one nozzle with the propellant gas.

9 . The movable tram of claim 8 , further comprising:

a respective control valve for each of the at least one nozzles; and

control circuitry configured to control the at least one control valve.

10 . The movable tram of claim 1 , further comprising:
