Hanako 2 robot acts like a human dental patient, makes us say 'aah' (video)

No, she's not in a state of shock, nor is she hunting for plankton -- she's simply waiting for the dentist to polish her pearly whites, just like any other conscientious robot. Known as the Showa Hanako 2, this humanoid was originally developed last year as a tool for dentists looking to practice new procedures. Now, engineers at Japan's Showa University have updated their dental denizen, adding a motorized head and replacing her PVC skin with a more realistic silicon coating. She also boasts speech recognition capabilities and can execute freakishly natural movements, including blinking, sneezing, coughing and, under more unsavory circumstances, even choking. See her in action for yourself, after the break.
