According to Xinhua, a graduate student at Japan’s Northeast University (东北大学) has invented a dancing robot. In addition to her pretty pink dress and well-defined breasts, the robot has sensors to anticipate her dance partner’s movements, and a complex wheel system that enables her to move in any direction.
