Robots Expressing Emotion, Nagging Coming Later
What makes Nexi so interesting is that "she" has been designed to communicate with not only the spoken word, but with facial expressions too.
"MIT's Nexi robot expresses emotions the same way you do - with your highly mobile face.
Nexi's head and face were designed by Xitome Design with MIT. The expressive robotics started with a neck mechanism sporting 4 degrees of freedom (DoF) at the base, plus pan-tilt-yaw of the head itself. The mechanism has been constructed to time the movements so they mimic human speed."
Nexi's voice is realistic and as you'll see if you check out this video, her facial expressions are obvious and actually pretty believable. Looking at the imagery, I'm reminded of "Sonny" from 2004's i-Robot movie. Kinds spooky, but exciting at the same time.
