This platform can autonomously collect Promethium and process it into Promethium Science Packs. It collects just over 8000 Promethium chunks during its voyage. Just add Biter Egg production on Nauvis.
It is largely based on this original ship by Ark
I added science processing as well as a number of upgrades to maintain ammo production without mods. I also added logic to handle biter egg disposal with timers, so you shouldn't have any biter egg spoilage.
