hmm! I feel like I ought to be able to rec you something with non-human-ish robots, but I am having trouble--you've already read Autonomous and Ninefox Gambit; Becky Chambers' AIs are going to be too people-like as well.

I was on a panel with Glenn Grant about robots and he'd written a story called "Burning Days" (in the collection of the same name) in which robots who want to be human are thought to need therapy for Pinocchio Syndrome, but I haven't read it and suspect it is probably not available in any useful way.
