Professor Fumio Hara and Assistant Professor Hiroshi Kobayashi's female face robot (second-generation) at Science University of Tokyo, Japan, has shape-memory electric actuators that move beneath the robot's silicon skin to change the face into different facial expressions much as muscles do in the human face. The actuators are very slow to return to their original state and remedying this is one of the research projects facing the Hara and Kobayashi Lab. The robot head is lit from within by a pencil light strobe cloaked in a yellow gel. It was photographed in the neon bill-boarded area of Shinjuku, a section of Tokyo, on a rainy evening at rush hour.
