Hiroshi Ishiguro (石黒浩 Ishiguro Hiroshi), director of the Intelligent Robotics Laboratory, part of the Department of Adaptive Machine Systems(知能・機能創成工学専攻) at Osaka University, Japan, developed the actroid, a humanoid robot and android with a lifelike appearance and visible behavior such as facial movements.
"In robot development, Professor Ishiguro concentrates on the idea of making a robot that is as similar as possible to a live human being; at the unveiling in July 2005 of the "female" android named Repliee Q1Expo, he was quoted as saying 'I have developed many robots before, but I soon realised the importance of its appearance. A human-like appearance gives a robot a strong feeling of presence. ... Repliee Q1Expo can interact with people. It can respond to people touching it. It's very satisfying, although we obviously have a long way to go yet.' In his opinion, it may be possible to build an android that is indistinguishable from a human, at least during a brief encounter" (Wikipedia article on Hiroshi Ishiguro, accessed 03-05-2011).
