So i wanted to make a resource bus.
The idea is that all the different resources are on a path and factory take the needed resource from the bus and put back production on to another transport belt for later use.
But as you can see i didn't followed this all the time :/
At least this doesn't need logistic robots.

production
also it's all solar powered, with backup steam engine which can handle the whole system on their own if needed.This is the solar layout i use ( here you see ~1200 solar pannel & 960 battery, which is half of the total)
