Hanako 2 Robot Acts Like a Human Dental Patient, Makes us Say 'aah'

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.
