Latest robots cooperate with humans

They are smart enough to solve puzzles in seconds, strong enough to lift metric tons of metal with ease, and they never complain about having to do the same thing repeatedly for 30,000 hours.

Robots have been playing an increasing role in factories for years, but now they are not just taking over jobs, they are cooperating with their human colleagues.

Several leaders in robotics research and development launched their latest technologies and products at the China International Industry Fair in Shanghai on Tuesday.
