What is the function of this? How to use it? Is there a video to show it?

I want to use cannons to send robots to new planets, is it possible?

place one down near your botmall, then on another planet try to place a ghost within roboport range, if the receiving network has space inside storage chests the turret will shoot the item to that zone.

it is only for construction materials though, to send robots you'll need to use the normal space exploration means.

Thank you reply, I don't know why the rocket can't landed in the new planets?

please rephrase your message.

I'm just searching a module for robots to landed on new planets.
I don't have to go to a new planet, just use robots to complete the construction.

you can launch spidertrons

I know, but that's the last technology. In SE+K2.
I imagine using human methods to send robots to new planets.
Building solar power, slowly from a robot, to a complete blueprint.
I just need to launch rockets from Navis to any planet.
Think about it. What type of game is Factorio now?

So spidertrons are not used, nor are they needed. Only the Navis Empire and battle droids exist. I am Darth Vader, and I am playing...

Next Mod. Death Star. ^_^ (Factorio II Star Wars)

You can live in the Halslam galaxy, and robots won't go that far. XD

well in either case this mod expects the destination surface to already have a roboport, in fact the mod depends on the missing construction material requests

So I'm searching a module can "Rocket landing" on the new planets.

I never understand, why can't "Landing"?
We can launch rockets, but we can't land them.
Why such a stupid idea?

to land rockets you have a landing pad
