Can a space-faring robot still function over a billion years?

+0
−0

This short story, which I've already written, is set in the FAR, FAR FUTURE, where a robotic space probe is exploring as much of the known universe as it can, despite its AI not knowing if its creators--humanity--still exists as a species. The exact number it has calculated to be slightly over a billion years since it first departed Earth.

Currently, could a robotic, humanoid space probe (a successor to the Voyager 1) be able to last 1 billion years or longer out in space, as long as it doesn't take on any external damage? If so, I'm curious what kind of materials don't deteriorate over time?
