Android is the human (animal) looking thing that is patrol the ship, running the flight controls, doing that simple medical procedure cause you can't not stand sitting in the medical coffin robot (auto medic box).
When I see some CG humans moving, I notice the uncanny valley they didn't quite cross. Sometimes they crossed it just fine, but they are still not quite human-looking yet. I wonder if the citizens of the 3rd Imperium experienced some sort of cultural uncanny valley with early android prototypes and then discontinued any further research?
Like the Twilight Zone where the doctor can't look at the woman's face, and everyone else is ugly. Well... maybe not quite like that.
