MIT'S new mini cheetah robot is the first four-legged robot to do a backflip. At only 20 pounds the limber quadruped can bend and swing its legs wide, enabling it to walk either right side up or upside down. The robot can also trot over uneven terrain about twice as fast as an average person's walking speed. Watch more videos from MIT: http://www.youtube.com/user/MITNewsOf...
