There’s that automated robot system (ARS), or whatever his abbrevation is, that will build a pre-set structure in 48 hours. It literally works as it was programmed in Cpp, it has resources stack and a blueprint with a bunch of parameters bundled with it. I’m outta game of finding its jpeg online, but have read about it and remember it looks like a double-crane with a horisontal bar; thus it has two electric motor units and a carrier one that utilises them both in proprietary terms.
So it lays the foundations, builds the cups in corners and also the pillar ones, fills them with steel bars and works on. One could use this knowledge to add sauce for building something similar in our own Public W’s.
