Japan leads robot revolution
There are robots serving as receptionists, vacuuming office corridors, spoon-feeding the elderly. They serve tea, greet company guests and chatter away at public technology displays. Now startups are marching out robotic home helpers.
Japanese are more accepting of robots because the native Shinto religion often blurs boundaries between the animate and inanimate, experts say. To the Japanese psyche, the idea of a humanoid robot with feelings doesn't feel as creepy - or as threatening - as it might do in other cultures. Still, Japan faces a vast challenge in making the leap from toys to full-blown human replacements.
At a university lab in a Tokyo suburb, engineering students are wiring a rubbery robot face to simulate six basic expressions: anger, fear, sadness, happiness, surprise and disgust.
Hooked up to a database of words clustered by association, the robot - dubbed Kansei, or "sensibility" - responds to the word "war" by quivering in what looks like disgust and fear. It hears "love," and its pink lips smile.
"To live among people, robots need to handle complex social tasks," said project leader Junichi Takeno of Meiji University. "Robots will need to work with emotions, to understand and eventually feel them."
