Let’s file this under “cool but kinda creepy”: Hanako is a Japanese-built robot created by three universities and a robotics manufacturer whose purpose is for training dentists. Her mouth is filled with sensors that are designed to react to the dentist’s tools. She also sneezes, screams if poked too hard, and salivates in an attempt to recreate a regular patient’s reactions. Other actions involve rolling her eyes in pain, wiggling her tongue, and opening and closing her eyes.
It’s a cool idea — I just wouldn’t want to be near that thing in a dark room.
