Nearly two years after it was introduced to the world, Osaka University's CB2 robot (which stands for "Child-robot with Biomimetic Body") has been developing social skills by interacting with humans and watching their facial expressions, just like a human baby would:
Below the soft silicon skin of one of Japan's most sophisticated robots, processors record and evaluate information. The 130-cm (four-foot, four-inch) humanoid is designed to learn just like a human infant.
"Babies and infants have very, very limited programmes. But they have room to learn more," said Osaka University professor Minoru Asada, as his team's 33 kilogram (73 pound) invention kept its eyes glued to him.
The team is trying to teach the pint-sized android to think like a baby who evaluates its mother's countless facial expressions and "clusters" them into basic categories, such as happiness and sadness.
