Advance Media Inc. and Kokoro Co. Ltd, designed a humanlike female robot for the 2005 World Expo in Aichi, Japan. In the event--according to We Make Money, Not Art--robots will greet guests, entertain children, and perform rap music.
Quoted from the Nedo site about the female robot, which is called "Actroid":
When communicating with a guest, ACTROID responds with natural gestures such eye movement and smiling.
This is the natural gesture to say "I cost THIS much!"
UPDATE: IT CAN'T RAP, BUT BOY, HOW IT CAN ENHANCE YOUR KIDS' ACADEMIC ACHIEVEMENT!
Andi Saptono pointed out that there are other robots listed in the Nedo site. For instance, the PaPeRo, a childcare robot that "can learn contents to increase the knowledge of children and enhance their academic achievement."
Andi wasn't sure whether he should feel "awed or freaked out."
