Self Propagating Autonomous Robotic Colonization and Exploration
     Todays technology allows mankind to produce anything he desires. Robots produce many of the items we use everyday. They are used to produce cars, electronics, conputers, building materials, and food just to name a few. Imagine if we could take all the little parts and combine them to make a single system to produce all we need, without human intervention. For example, create a robot to mine the soil, another one to process the soil into elements, another to create parts, another to assemble parts and one to build a structure. If we expand this a little further, we produce the system as listed below.
The main system will comprise of about 1000 robots. Each robot will preform only one task. For example, to produce aluminum bars, I will need to mine the soil, extract the aluminum, and cast the bars. But this can be expanded even further - to mine the soil will require the following robots: excavator, rock hammer, crusher, grinder, loader, dump truck, grade checker.
By breaking it down into tasks, each robot will be cheaper, smaller, easier to reproduce, and less likely to have a massive system failure. And, with a 1000 different robots working at the same time, you could accomplish 1000 tasks at the same time.
