A Stewart platform for a head with wobbly antennae for secondary movement is incredibly expressive! The line between robot and animatronic is often blurred. I know there are industry definitions—or at least de facto conventions—but for me a robot is something that performs and controls "mechanical work" based on external sensing or input. For me, the output "work" isn't meant to solely be character expression. That said, animatronics from Disney Imagineers really blur the line for me.
