I remember having read a book about a robot that was in charge of a space ship, while the human commander was in some sort of sleeping state. The robot broke down and was mostly talking gibberish. I think it got fixed by a civilization that the ship stumbled upon.
I read the book around 2010, but I know for a fact that it was written before the 2000s(it was an old book that my father had in his childhood). I'm also pretty sure that the book had an almost monochrome cover. I very rarely remember the author's name of most of the books that I read, but I'm quite positive it wasn't Asimov or Cliford D. Simak(I read books by the both of them in that period and would most likely remember if any of them was the author).
The book itself was translated and I have no idea in what language was it originally written. I think the title had Odyssey or a similar word in it, but couldn't find anything after searching online.
I'll update the post if I remember anything else.
