Student Yousuke Kato points to a female face robot created at the Science University of Tokyo, Japan, Fumio Hara Robotics Lab. The female face robot (secondgeneration) has shape-memory electric actuators that move beneath the robots' silicon skin to change the face into different facial expressions much as muscles do in the human face. The research robot undergoes a metamorphosis with each class of students assigned to work on it. The latest iteration allows the robot's face to mold into six different expressions: happiness, sadness, fear, disgust, anger, and surprise. In some images, the computer monitor displays a graphical representation of the software creating the expression on the robot.
