In the 2011 CBS show Person of Interest, reclusive computer scientist Harold Finch builds an artificial intelligence system called "the Machine" that compiles and analyzes troves of data to predict murders. Finch and his henchman, John, then chase down the perpetrator and prevent the crime. Public security officials in the Chinese autonomous region of Xinjiang, it turns out, are turning that fiction into fact. An enormous data-driven program that pulls from health records, financials, vehicle checkpoints and police reports to identify individuals likely to commit crimes in China's politically sensitive northwest region has just been revealed. Launched in 2016, the "big data" policing initiative in Xinjiang is one of many law enforcement initiatives the country is launching, drawing on its growing capabilities in the fields of AI and robotics. While a number of countries … boast the technological capabilities China is integrating into law enforcement, political considerations make it difficult for these countries to follow suit.

Wang Gongxian, vice director of the First Affiliated Hospital of Nanchang University introduced that the robot arm with the operating forceps can freely rotate 540 degrees, which is more flexible than human arms. Wang added that the trauma caused in operations performed by surgical robots can be smaller and the treatment can be more precise compared with traditional operations. Robot arms were designed according to the functions of human hands. They will not tremble even if a doctor's hands shake, said Ou Yongsheng, a researcher at Shenzhen Institutes of Advanced Technology under Chinese Academy of Sciences. In addition, the robots will immediately stop working in case of an emergency, such as instable voltage or power failure, Wang noted.
