Key Ideas • Don't launch it; evolve it • Not a simplistic "self-replicator" -The biosphere and industry are not self-replicators
• Use "Appropriate Technology" at each step - It doesn't need to be low mass or high tech - It needs to be easy to make in space
• The technologies are already being developed -Simply "spin them in"
• The technologies are advancing exponentially
Generations of Space Industry (Notional) Gen Human/Robotic Interaction 1 Teleoperated and/or locallyoperated by a human outpost 2 Teleoperated
Scale of Industry Artificial Intelligence Insect-like Imported, small-scale, limited diversity
Lizard-like
(Same) Crude fabrication, inefficient, but greater throughput than 1.0
Import electronics boxes
2.5 Teleoperated
Lizard-like
Diversifying processes, especially volatiles and metals
Plastics, rubbers, some chemicals
Fabricate crude components plus import electronics boxes
Lizard-like
Larger, more complex processing plants
Diversify chemicals, Locally build PC cards, chassis Simple fabrics, and simple components, but eventually polymers. import the chips
Materials Source of Electronics Manufactured Gases, water, crude Import fully integrated alloys, ceramics, machines solar cells
3
Teleoperated with experiments in autonomy
4
Closely supervised Mouse-like Large plants for chemicals, autonomy with fabrics, metals some teleoperation Loosely supervised Mouse-like Labs and factories for autonomy electronics and robotics. Shipyards to support main belt
Sandwiched and Building large assets such as other advanced lithography machines material processes · Large scale Make chips locally. Make bots production in situ for export to asteroid belt
Nearly full autonomy
Makes all necessary materials, increasing sophistication Material factories specialized ·by zone of the solar system

X.O Autonomous robotics pervasive throughout solar system enabling human presence
Monkey-like Large-scale, self-supporting industry, exporting industry to asteroid main belt Human-like Robust exports/imports through zones of solar system
Makes everything locally, increasing sophistication Electronics factories in various locations
FromGen N -1, Gen. N contains Z
•Simplistic Modeling •Not intended to be definitive •Explores some of the key parameters •Attempt to demonstrate basic feasibility •Intends to generate interest and further investigation •Needs a much larger study with a much larger group of contributors

The Robosphere • Like an Ecosphere • Like a living cell • Beautifies the solar system • Allows us to live at the top of a food chain • Enables us to do great things - Terraforming, colonies -Science, arts -Interstellar travel
.
Cost/Benefit • Cost: - Develop and launch 12 to 60 tons to Moon and operate it for 20 years - Launch costs will be negligible using newer capabilities - Comparing to cost and mass of ISS, this will be less expensive than ISS • Most mass will be redundant hardware, not unique items
• Benefit - Move from being a Type-1 to a Type-2 civilization • Solve world economic problems • Make our existence safe in the solar system • Brilliant possibilities for the future
- Move toward a Type-3 civilization • Extend human presence through the Milky Way
