Because this mission is so hard I propose to divide the workload into steps. Step 1 consists in making the robot create it's own power source. It will only use solar power at the beginning because any other source will be orders of magnitude harder to accomplish and more expensive (nuclear, RTG, fuel..).
Question: How large and how heavy do you believe the first robot would be if it had the capability to swallow soil and reject inter-connected solar panels behind it. This would be similar to “Living on the moon” concept but at a much smaller scale because we are constrained by launch weight.
If we get a launch it will have to be funded with crowd-sourcing such as kickstarter and it probably won't cost more than $100,000 (very easily achievable on Kickstarter).
I would like to add none of any money raised will pay people working on the project. Only materials will be bought. Work will be volunteered, so as to respect the open-source spirit and avoid corporate or governmental control, for profit-motivated enterprise has proven to be too slow for human progress.

we have www.gnuspace.org
:)
It does not lead anywhere yet because we need to host it still.

What happened the wiki?

Need a tl;dr

I spy kickstarter, not enticing.

Found it.

I've had ideas for autonomous exploration/swarm bots and did a little research into engineering for space. May be interested enough to dig it out and look over it again

>1-explore the area
>2-enumerate the resources quantitatively and let the software measure work priorities according to the objectives, the resource
locations and distances between resources and location of base construction, engage fail-proof survival-mode
self-replicating manufacture so robot numbers/mission intelligence/efficiency of mining and smelting can be multiplied over time
>3-establish robotic factory/base
>4-produce enough robots to safely install human habitat
>5-install human habitat (dome, water and air systems, bathroom and food systems, greenhouse, communication center, rec room)
>6-build space port for human landing and transfer
>8-prepare base for human takeover
>7-test habitat with different levels of catastrophe simulators

I suggest searching for any archives from Project Sovereign /sov/, anon exploring the idea of becoming a legitimate sovereign nation.

The idea ultimately came to a halt but any discussions on infrastructure may be worth something.

>>5523353 >how long did that last
Few months, 888chan provided a home until it disappeared.

>why did it stop?
Because it was Anonymous trying to start their own nation on an imageboard

It is an on and off thing.

The main problem is a lack of capital.

you mean lack of vision, direction and plan.

I'm gonna need people to look into small solar panel manufacturing.

No but i bought gnuspace.org lel.
Can u ask /g/ for a server to host it?
I ll also sign up for the wiki but im in class right now.

Have you read the other threads yet? You might want to start with that. Because right now you are still in denial.

[Anonymous No.5523957]

Conker here, seems I didnt lost much.
Well regarding solar panels, I think its not reliable to start ptoducing them directly. Lunar made solar plants would be really crappy. Payloaded panels seems the way to go. And, once again, we need high power for power tools. Mining would require RTGs.
In 3d lunacrete printing, what would be better: compresed regolith then steam, or lunacrete extrusion?

[Anonymous No.5524101]

If I understand this correctly, you plan on building a robot that is capable or finding raw materials buried in the sands of mars, digging them out, processing them, and building a entire base?

Then you want to load it up in a rocket, and land it on Mars?

[CuriousJon !!2vOa6TWjV3b No.5524167]

It seems to me that the main crucible in the Gnuspace plan is Robot Design. Do you have a Designer yet? A skilled person to invent a robot that will do the tasks required?

[Anonymous No.5524189]

>>5524167
I'm capable of covering a large portion of the mechanical design phase. Electrical and computer engineers will be required to help design and manage the control systems.

[CuriousJon !!2vOa6TWjV3b No.5524204]

>>5524189
what about software design? Are we partnered up with /g/ to get the coding?

[Anonymous No.5524207]

>>5524189

I'd like to note that closed-loop automated systems are /the/ big player in future missions anywhere. Example: It's unrealistic to send 300 rovers to Mars that require the same manpower as Curiosity/Spirit&Oppy (ignoring the 30minute delay between commands)

[Anonymous No.5524213]

>>5524204

I have basic experience in programming PLCs and designing pneumatic/hydraulic logic circuits.

There's a lot of work needs completed before anyone should consider beginning to code anything.

[CuriousJon !!2vOa6TWjV3b No.5524229]

>>5524213
What's the point in waiting to build the code?

the way this project is going to work, according to OP, is to divide the workload. If the coders aren't doing anything and just sitting around waiting for the engineers to build it and the electricians to wire it, then they are wasting time.

I do understand that there is a lot that can't be done with the coding until the bot is made to input the coding to, but the framework, basic variables, and definitely the interface could all be built before the hardware is ready.

>>5523141
So you want to make a self-replicating robot factory? Excellent, the memetic seeds I've plant seem to have sprouted.


>> Step 1 consists in making the robot create it's own power source.
done, Magma electrolysis--> silicon and iron melt--> vacuum refining --> vapor deposition onto molten regolitih along with dopants and wires---> solar cells

http://www.niac.usra.edu/files/library/meetings/annual/jun00/433Ignatiev.pdf
Pic very related.

Of course, you need to get magma electrolysis working first and you need a way to reliably mine lunar regolith.

Mining regolith is a surprisingly hard problem, as we don't really understand the mechanics of powders all that well.

Factories that process rocks and powders on earth don't work very well and need continual maintenance to stay working, something that's going to be hard to accomplish on the moon.

>>How large and how heavy do you believe the first robot would be if it had the capability to swallow soil and reject inter-connected solar panels behind it.
probably fairly large, though you'll have to do the math on it

I'd also tend to stay away from mapping the immediate surroundings and doing things autonomously in the early stages, there isn't much time lag between the earth and the moon, so teleoperation is possible.

[CuriousJon !!2vOa6TWjV3b No.5524267]

>>5524245
can you explain your thought's behind staying away from mapping....doing things autonomously?

[Lunatic !!IE/X7lbCDOY No.5524281]

>>5524213
that might be useful, some plans for self-replicating robots call for extremely simple control using relay logic.

After all, relays are a lot easier to make than microchips. Link below

http://www.niac.usra.edu/files/studies/final_report/880Chirikjian.pdf

Almost forgot, the above proposal has the self-replicating factory produce MASS DRIVERS to launch seeds for itself.

[Lunatic !!IE/X7lbCDOY No.5524307]

>>5524267
What do you need mapping for in the first place? The glorious Soviet Lunokhod rover didn't do any mapping, it was operated all by people down on earth.

And as I said before, the ping to the Moon isn't all that bad. Teleoperation will also allow you to work out the kinks before moving on to full autonomy.


That being said, I'd like to join this project.
