A visit to the dentist is something that many children fear, with some youngsters thrashing around in the chair while the dentist tries to inspect their mouth. Now, Japanese scientists have developed an eerily-realistic robot child, which they hope will make it easier for dentists to manage encounters with nervous patients. The robot, called Pedia_Roid, can move its arms, legs, and eyes to mimic several human emotions, including anxiety, fear and resistance. However, dental students hoping to try the robot themselves may be saving for a while – in its current iteration, Pedia_Roid costs a whopping 25 million Japanese yen (£153,000). The robot has a total of 24 degrees of freedom, and can move its head, mouth, tongue, eyelids, eyes, pupils, arms, legs, chest and even pulse.
