There are approximately sixty motors in the small space of the robot body that make the expressive movement of the robot possible. The Personal Robot Group developed the motor control systems (with both 8-axis and 16-axis control packages) that they’ve used for Leonardo. Leonardo does not resemble any real creature, but instead has the appearance of a fanciful being. Its face was designed to be expressive and communicative since it is a social robot. The fanciful, purposefully young look is supposed to encourage humans to interact with it in the same way they would with a child or pet.
