i would suggest that we shouldn't base our opinions of this idea on robots from other media, BUT if you must, then i would point you to something more along the lines of I-robot or Wall-E.
these robots will be juvenile at first. their innocence showing through as they evolve or "grow-up". their society would be brand new and could easily be shaped by the actions of the factions around them since they really wouldn't have much of a history of their own.
try not to dwell on the stigmas created by existing concepts you see in other media but think of the positive possibilities of something new and not imported.
again i'm thinking of this as being more of a house than a faction.
