Each mask is made of soft, flexible silicone, carefully molded and stretched over the robot’s mechanical face. Beneath it, tiny motors and sensors move in sync — creating facial gestures that look strikingly human. This process is part of a growing field called social robotics, where scientists are building robots that can com
