With President Donald Trump and Chinese President Xi Jinping's high-stakes summit underway in Beijing, the global race to lead on Artificial Intelligence and robotics technology is on too. "World News Tonight" anchor and managing editor David Muir traveled to one of the biggest AI Developer Conferences in China to see the machines firsthand, meeting Chinese robotics company Limx Dynamics' humanoid robot, named Oli. Standing at 5 feet 5 inches tall and weighing in at 121 pounds, Oli marched forward, and developers said it is programmed to do household chores such as folding clothes, washing dishes, cleaning the house and even making the bed. Unlike other robots, Oli can mimic human waist and hip movements, giving it the ability to lay down and sit back up on its own. Developers said Oli's flexibility underwent extreme tests, from walking through deep snow in Northwestern China in Arctic-level temperatures to moving on rollerblades and ice skates. Limx Dynamics said Oli will not only help at home, but also in factory labor, and won't replace humans but will instead take on some of the work that humans do. Some estimate that Chinese humanoid robots account for nearly 80% of sales worldwide. Just this week, Limx Dynamics revealed their newest model, the GD-01, which transitions from two to four legs and is able to carry a human.
