This frightening animated robot is for training dentists. I don't know about you, but I'd rather practice dentistry on a white cockroach.
Simroid’s body and control system was developed by Kokoro Company Ltd., creators of the Actroid receptionist robot. Like her Actroid sister, Simroid is equipped with a system of air-powered muscles and soft silicone skin. However, she has something the Actroid does not – sensitive teeth. Thanks to a mouth loaded with sensors, she knows when her dentist-in-training makes a mistake. And to express her pain, she grimaces, moves her hands and eyes, and says, “That hurts.”Link
Kokoro says that for an extra touch of realism, Simroid exhibits a gag reflex when instruments are inserted too far into her mouth.
