Humanoid Robot: Dental Patient

I just came across with an article in Yahoo! News today while signing out of my Yahoo! mail. It's interesting that a humanoid robot that can exclaim "ouch" or frown can help train students at dental schools to develop skills to better deal with patients' pain during dental drill. "The point is that we can share people's pain without hurting people," Matsuzaki (an official at robot maker Kokoro Company Ltd.) said. Isn't it amazing?
