How far can the repair bot go to repair?

[Lucius Confucius]

When I asked it about its repair ability it said it repairs nodes within its sensory range. How far is that range?

I currently have two repair bots in my workshop II on the top level of my ship. Will they be able to got to repair in the lower levels?

Not sure, but you'd want them on some patrol, and they'd probably at least need to be in the immediate area not a couple floors up.

At one point, I had a layout with a service bot on patrol in my red zone (tractor/hangar/deposit/refinery) and quarters built three levels directly above the area, and the bot went up to the quarters to repair nodes during pirate attacks.

Given the way a lot of things work in the game, I wouldn't be surprised if the sensor range counts only horizontal distance and ignores vertical distance entirely, but I've made no attempt to test that.
