BigDog, the alarming life-like, four-legged robot, is back in action. And this time, it’s trudging through snow, marching up hills, and picking itself up after slipping on some ice.
The machine has always been surefooted — staying on his feet after swift kicks to the flank. But the Pentagon-funded ‘bot is getting stronger, and more resilient. It’s now carrying a 340 pound payload, up from 150 pounds before. Which means the military’s goal, of giving soldiers a robotic pack mule, to haul around their gear, is getting closer.
