The only planet completely populated by robots.
The other machine adventures are not even on planets :)
PoC or GTFO.
I think it's pretty fair to describe the remains as dead robots similar to folks talking about their coke-bottle decks (recycled plastic) or even a sword forged from the remains of dead robots - I'd still consider that to be made of dead robots even though very little remains outside of the mineral composition.
I mean, aside from most oil being composed of dead plants rather than dinosaurs (if I remember right). Unless you're counting the bits of dinosaur absorbed by those plants before they turned into oil, but I feel like at some point they stopped being dinosaur and started being plant.
It does have ongoing volcanism, though.
