Robot dog can walk after ONE hour of training as scientists hope it can play fetch in the future

Scientists revealed a robot dog that can teach itself to walk in just one hour. In a video released by researchers, the 4-legged robot is at first seen flailing its legs in the air and struggling - but after just 10 minutes it can take steps - and by the one hour mark it's walking quite easily, rolling off of its back and even navigating being knocked over with a stick by one of the researchers. Unlike many robots, this one was not shown what to do beforehand in a computer simulation. Danijar Hafner, an artificial intelligence researcher at the University of California, Berkeley, worked with his colleagues to train the robot using reinforcement learning. A robotic dog has been trained to walk, roll over and navigate obstacles in about an hour, University of California at Berkeley researchers reveal. This type of machine learning is concerned training algorithms by rewarding them for taking certain actions within their environment.
