Hierarchical assembly of self-replicating spacecraft using distributed mechanisms and actuation in digital materials
A system of flexural, actuating, and semiconducting elements of part-types necessary to assemble actuated robotic systems. These parts are joined with a common interface, interlocking with neighboring parts to form a regular lattice structure. Primary considerations for the design of the part interfaces include ease of assembly and the ability to transfer mechanical loads and electronic signals to neighboring parts. The parts are designed to be assembled vertically so structures can he built incrementally one part at a time. They can be easily fabricated at a range of length-scales using a variety of two-dimensional manufacturing processes. These processes include, for example, stamping and laminating, which enable high-throughput production. The simple mechanical interfaces between parts also enable disassembly allowing for reconfigurability and reuse. The interlocking nature of these assemblies allows loads to be distributed through many parallel load-paths.
