Uncanny valley, heard of it? No worries, you're knee-deep in it right now. It's the revulsion you feel to robots, prostheses, or zombies that try, but don't quite duplicate their human models. As the robot becomes more humanlike, however, our emotional response becomes increasingly positive and empathetic. Unfortunately, the goal of Osaka University's AFFETTO was to create a robot modeled after a young child that could produce realistic facial expressions in order to endear it to a human caregiver in a more natural way. Impressive, sure, but we're not ready to let it suckle from our teat just yet.
