Next generation of robots almost as dextrous as a human

It's quite common for humans – especially those who work in manufacturing – to tie a knot, strip the casing off a cable, insert a pin in a hole or use a hand tool such as a drill. They may seem like simple tasks, but are really very complex and involve extremely fine finger and hand motions. Though robots are getting more and more involved in factory work and in a wide range of other types of jobs – including in the service industry and health care – their dexterity is not nearly as impressive. A NASA Valkyrie robot picks up an item with its hand. The robot is six-feet tall and weighs 300 pounds.
