ONE PERCENT

摘要

When robots get too lifelike they creep us out, thanks to the "uncanny valley" effect. To create one we are more likely to accept, Nicole Lazzeri and colleagues at the University of Pisa, Italy, have come up with a robotic face that can recreate realistic human expressions (pictured). Motors replicate the movement of real muscles to manipulate the polymer skin around the robot's skull. Each movement is based on a 30-year-old coding system that describes which face muscles move to create a particular expression.
