here is how i completed it.
build security module, robotics module, industrial module with 1 spare 1 semiconductor and 1 gun modules, medium agricultural module, exterior airport module, acquire patent for contructor robot from a macrowaves representitive and build a bot manufactory module inside my robotics module, buy a few driller bots from the same trader then build a mining module and prossesing plant and on your landing permissions bring workers to 100% and get a prossesing module. just accumulate 15 ore and survive. then build 10 constructor bots in 10 days (give high priority to robotics module if nessesary). HINT, this is like my challenge absolute hell but with a difference, you have no workers so until you get workers, you must buy everything and why a gun module so I have something to trade in. My guns are my only source of money and I don't stockpile gun because no intruders.

Hint A- you can build connections over lakes B- Get drill bots because workers don't work in the mine C- since constructors are very expensive, it helps to get technology
