to overcome the wind issue ?
Sorry, but no. I considered it early into development and quickly scrapped it because it really kills what makes Rubia unique. The entirety of Rubia's optional postgame content is structured around making setups that are much more complicated because Rubian trains are the only way to oppose the wind.
wall to block wind effect ? walls with turbines to protect some areas ?
Craptonite walls were originally intended to have a wind-breaking mechanic. I tested this idea last month. A user very quickly figured out how to use wagons + inserters to teleport items left, and then several other degenerate strategies for leftward movement, so I had to scrap it.
specials Scapbots, spidertron small crawling bots ? instead of flying bots ?
This is not possible with Factorio's API. Any automated leftward movement on Rubia must use Rubian trains, and I cannot apply such a restriction to logistic bots because Factorio does not support it.
