Charles, a robot built by researchers at Cambridge University in the U.K., mimics human facial expressions.

Charles is equipped with computer programs and servos linked to a camera that captures the faces of people who interact with it; this footage is analyzed to measure the positions of facial aspects prior to feeding this data to Charles. Charles then uses this information to guide its servos to replicate the actions of human facial muscles.

"We've been interested in seeing if we can give computers the ability to understand social signals, to understand facial expressions, tone of voice, body posture, and gesture," says Cambridge professor Peter Robinson. "We thought it would also be interesting to see if the computer system, the machine, could actually exhibit those same characteristics, and see if people engage with it more because it is showing the sort of responses in its facial expressions that a person would show."
