A dentist demonstrates a training procedure, using the new humanoid robot named Hanako which was developed by local engineers at universities and a robot maker to aim at training experience to simulate real dental work for student dentists, at Showa University in Tokyo Thursday, March 25, 2010. Hanako is equipped with the set of teeth made of hard plastic and lifelike mouth cavity which can bleeds and flows saliva just as human reflects against stimuli. It also has voice recognition and speech capability so that trainees can just not only improve treatment skill but also learn to hold conversation with the patients to relax them.
