Humanoid robots win half marathon in Beijing

On Sunday, a robot called Lightning, made by Honor, a Chinese smartphone maker, won a half marathon in Beijing in just 50 min, 26 sec. That's several minutes faster than the human world record-holder, Uganda's Jacob Kiplimo, who finished the same distance in 57 min, 20 sec, earlier this year in Lisbon. Several other robots in the race outran humans for the first time. Host Marco Werman has the details.
