Chinese robotics researchers have created a humanoid robot named Jia Jia, who can move her arms, make different facial expressions, and respond to human conversation. Jia Jia, the product of three years' work by a team at the University of Science and Technology of China in Hefei, greeted the assembled audience at her unveiling by saying: "Hello everyone, I'm Jia Jia. Jia Jia's limited motion and stilted speech shouldn't leave anyone in any doubt she's a robot. However, she looks fairly realistic, with a flexible plastic face, long flowing brown hair, and an eye-catching gold dress. According to the team's director, Chen Xiaoping, particular attention was paid to her eye movements and lip synchronisation.
