Like, not technically how, but emotionally? If I spend too much time messing around on a platform, critters inevitably attack my base. Even if I build a fortress, I worry that something will run out and guns will run out of ammo... or that something will run out and The Factory will grind to a halt. I could just stack up a vast area of capacitors and rely on lasers and a fission reactor, but is this really what you guys are doing?
How do you emotionally detach from Nauvis and commit to not being able to troubleshoot on the home factory? Heck, once I establish factories on other planets, how do I leave them to return to Nauvis and not worry that they'll be overrun??
When Space Age was released I restarted, solo, with a new base, and I'm getting close to building a traveling platform; how do I ensure the security of Nauvis before I depart?
(My first, and as yet only, station attached for giggles)
Practice managing your base only through remote view, do everything through remote view. It's pretty good. You can do anything.
Roboports will provide radar coverage even without power. Robots will move very slowly even when powers out.
If you're worried about biters, make sure you have defense in depth, so you have time to respond if something goes wrong. I.e. Wall of lasers, behind that a wall of gun turrets and flamethrowers.
Before you leave the planet make sure your robo network is entirely self-contained, maybe a square, or a circle. So that none of your robots have to fly over enemy territory
Use alarms! Set them up for every base. Low fuel, low power, low iron, low ammo, etc, etc
