Inside China's experiment to find friends for 230 million old people

Care bots are part of a big bet China's making on robots. The country is already the world's largest producer of industrial robots and the largest buyer of robots in the world. China's factories spent more than $3 billion on industrial robots in 2015, according to the International Federation of Robotics and Bernstein Research. The government is also focused on developing service robots, and has laid out a plan to turn it into a 30-billion-yuan industry (about $4.35 billion USD) by 2020. A big part of that will be caregiving and companion robots for the elderly.
