They can dance and they can sing. But only one of the robots on display at this year's Taiwan Robot Fair can express an opinion. Designed by electrical engineering professor Rain Xi Low. He's called a low head, created the image of a young and very expressive Albert Einstein. The Einstein robot can emulate 7 different human emotions including joy,disgust,and astonishment.

There's a camera system installed in the eyes, and in the robot's face, there're installed 36 motors,and every single one of the motors can take 256 positions. Like this, the robot can create very many different facial expressions.

Low's robot has beend esigned to look like Einstein at 27 years of age when he published his famous theory of Relativity. The professor and his students plan to give him a body and legs so he can walk, although Einstein himself seems to have mixed feelings about the idea.
