MakerBot Replicator + 3d Printer

Product Information

Much of the design study was concerned with a simple, flexible chemical system for processing lunar regolith, and the differences between the ratio of elements needed by the replicator, and the ratios available in regolith. The limiting element was Chlorine, an essential element to process regolith for Aluminium. Chlorine is very rare in lunar regolith, and a substantially faster rate of reproduction could be assured by importing modest amounts.

In 2004, General Dynamics completed a study for NASA's Institute for Advanced Concepts. It concluded that complexity of the development was equal to that of a Pentium 4, and promoted a design based on cellular automata.

The design space for machine replicators is very broad. A comprehensive study [8] to date by Robert Freitas and Ralph Merkle has identified 137 design dimensions grouped into a dozen separate categories, including: (1) Replication Control, (2) Replication Information, (3) Replication Substrate, (4) Replicator Structure, (5) Passive Parts, (6) Active Subunits, (7) Replicator Energetics, (8) Replicator Kinematics, (9) Replication Process, (10) Replicator Performance, (11) Product Structure, and (12) Evolvability.

Clark said that if Replicator is being put to the test, there are several things the Defense Department would need to do.

Romulan replicators left distinctive patterns in the molecular structure of items they produced. ( TNG: " The Mind's Eye") A more speculative, more complex microchip fabricator was specified to produce the computer and electronic systems, but the designers also said that it might prove practical to ship the chips from Earth as if they were "vitamins."Brief Mathematical Primer on Self-Replicating Systems".

I think the lesson there is we got to figure out ways to enable our unmanned systems to be employed in a very flexible way that tactical operators can then adjust in the field.” NVIDIA Isaac Sim™ is a scalable robotics simulation application and synthetic data-generation tool that powers photorealistic, physically accurate virtual environments to develop, test, and manage AI-based robots. Isaac Sim uses Omniverse Replicator as its powerful synthetic data-generation engine.
