Simroid is a robot designed to help dental students improve on their patient communication skills. The video below is an interview with Dr. Naotake Shibui of the Nippon Dental University in Tokyo, who helped develop the Simroid.

According to the interview, Simroid is modeled after a 28-year-old woman, and her fear of dentists and sensitivity to pain have earned her the nickname “Pain Girl” (Ita-gaaru). Asked why Simroid is female, Shibui explains that female patients must be treated with more sensitivity than male patients. With sensors embedded in her chest, Simroid can teach dentists-in-training to pay close attention to where they place their elbows.

One of the features of Simroid is that she exhibits a gag reflex when instruments are inserted too far into her mouth.
