Trying to concentrate in a crowded, busy workspace, graduate student Harumi Ayai pats makeup onto the immobile features of a face robot in the Hara-Kobayashi Laboratory. This machine, the first face robot built in the lab, has a single camera in its left eye.

Although rapidly superseded by later models, the lab went through three generations in a few years, the robot is still being studied. Japan.
