Which is to say, they apparently have not done anything yet but are rather stating their intention.
"There are 10 lights-out (fully automated) production lines at some factories, including table one in Chengdu, AIO (all-in-one) PC and LCD monitor lines at a factory in Chongqing, and a CNC line in Zhengzhou. ... Foxconn has deployed more than 40,000 Foxbots, industrial robots developed and produced in house, at factories in China."
The Chengdu plant makes iPads.[1] Foxconn refers to "table one" because they usually don't name their contract manufacturing clients.
Apple used to have robotic assembly lines in Fremont, CA.[2] Then they switched to cheap outsourced manual labor.
