As the title says, a late-game setup for Green Science Packs. It produces steady 1k/min and is entirely fed with bots.
If you ship in all materials by train, you could easily set up train stations next to the roboports.
It needs to be provided with:
~ 3,5k Iron Plates
~ 800 Copper Plates
per minute, and needs ~80 bots to operate (@ worker robot speed 12).
