We cringe when thinking about dentists, but now they will get their just desserts with Simroid, a 5 foot, 3-inch bot developed at Nippon Medical School which will teach them how to better communicate with their patients. If the dentist hits a nerve with his/her drill, she will say “ouch” and will react to pain by moving her eyes and hands. If she is touched in an inappropriate place on her chest, she will record that to later incriminate the offender. Simroid was unveiled at this week’s 2007 International Robot Exhibition. Don’t push play if you are as squeamish as we are. (Just kidding.)
