A humanoid robot that can interact with people

The robot head, known as 'Han', can also hold simple interactive conversations with the crowd. At the touch of a button using a mobile phone app, Han can smi le, wince, frown, wink, or even act drunk. About 40 motors control his face to form delicate facial expressions, according to product manager at Hanson Robotics, Grace Copplestone.

The robot can also respond to his environment, thanks to several cameras inside his eyes and chest. "So Han's really exciting because not only can he generate very realistic facial expressions, but he can also interact with the environment around him."

Copplestone said. A unique feature of Han is his human-like skin, which is created by a patented material called 'frubber', short for 'flesh rubber', an elastic polymer. The Hong Kong based company aims to commercialise Han's technology on a different face, an Eurasian female called Eva, and plans to produce hundreds of Evas this year.

The price is yet to be determined. Han made its debut to the public earlier this year in January, during the Digital-Life-Design fair in Germany.
