A colony established by whoever left those robots behind. There is a robot factory on the surface, and a building teeming with robots and robot building computers.
The main obstacle on this planet is a very well programmed automated defense system: A turret with a disintegrator fires on any ship when it is in the last stage of landing. Fleeing out of the gravity well is no longer an option at that point, and only a good pilot will get the ship undamaged to the surface fast enough to avoid being vaporized.
Down on the surface you are greeted with the grisly sight of dozens of crashed space ship hulls. Good loot, if you can get one of them up again. But to do that you first need to disable the disintegrator. It is protected by a forcefield, so that is easier said than done.
