Robots Race Against Humans in Half-Marathon in China

In the race to build robots that are faster and smarter, big strides are being made in China where a half-marathon pitted more than 100 humanoid robots beside 12,000 real-life runners. The winner, a machine called Lightning, finished 13 miles faster than any human ever, shattering the world record by nearly seven minutes. NBC’s Janis Mackey Frayer reports for TODAY.
