It's one thing to make a robot that can run around, but what about one that can do it blind? MIT's new Cheetah 3 quadrupedal robot answers that question by covering rough terrain in leaps, pounces and gallops, and even navigating stairs – all without sight. Instead, the dog-sized, 90-lb (41 kg) automaton relies on internal sensors and algorithms to produce what the engineering team call "blind locomotion."
