Google algorithm teaches robot how to walk in mere hours

A new robot has overcome a fundamental challenge of locomotion by teaching itself how to walk. Researchers from Google developed algorithms that helped the four-legged bot to learn how to walk across a range of surfaces within just hours of practice, annihilating the record times set by its human overlords. Their system uses deep reinforcement learning, a form of AI that teaches through trial and error by providing rewards for certain actions. This technique is typically evaluated in virtual en
