I present my space platform, capable of collecting Promethium. It may not be the most efficient or the fastest, but it is fully automated to constantly produce Promethium Science. Moreover, it is built almost entirely with normal-quality items.
Route:
Collects supplies on Nauvis for the dangerous interstellar journey
If ammunition reserves are below the established amount, the platform will make short trips to gather resources and manufacture ammunition
Once all conditions are met for the voyage to the shattered planet, the platform will begin its journey
On the way through Aquilo, it will collect quantum processors
After gathering the established amount of Promethium asteroids, the platform will begin its return trip home
Attributes:
The platform makes the interstellar journey with almost no damage, but stores reserves just in case
The platform has self-regulated speed depending on its travel direction
It is capable of accumulating more than 7,000 Promethium asteroids per trip
Important note: The platform’s descriptions are in Spanish since I am Argentinian. It would make me so happy if people tried it! It took me more than 10 hours to make and dozens more perfecting it.
