This robot, built by Boston Dynamics and funded by DARPA, is called BigDog. This is eye-popping:
I am not a roboticist, but I am in part an engineer, and I have an eye for excellence in design and construction. I’d say this is most impressive. BigDog is about a meter long and can carry over 300lbs. That buzzing sound in the video is its ordinary little gasoline engine. That’s all that powers this extraordinary four-legged metal beast of burden through forest and snow.
Just making an autonomous robot that can manage in the real world at all is a true challenge. Most efforts I’ve seen have the lamest limitations, like being unable to climb stairs or becoming as helpless as a flipped-over turtle if knocked over or if it just stumbled. Walking is hard. Even on all fours.
But this is an entirely different order of robot from the classic image of the clumsy, hobbling, tippy-toppy robots of–well–a couple years ago, or even today. Just look at how gracefully it recovers from that sudden, brutal shove! I would have fallen myself. And it goes plowing through the dirt and ice just fine, if a touch gingerly, as if tentative about its judgments of its environment. Of course there is much uncertainty and chaos in an environment of ice, dirt, rock, hills and trees. But this is just a research model, and I’m sure as its design is refined, so will its body language become more confident. But it seems to work pretty damn well already.
Its applications are as clear as the technical revolution it signals. Just as the robotic drones that now rain death from the sky, this sort of ‘heavy load-carrying over very rough terrain’ machine offers profound new capabilities to the military. Ask any soldier trudging through the wilderness with a backpack that weighs one third as much. Military funding is a mixed blessing, but such is how advanced technology is often originated (and incidentally, the work I do in computer science is a response to similar pressures). But having a machine that can carry heavy stuff pretty much anywhere you care to go (or direct it to) has countless death-free possibilities as well. Even quite the opposite. Consider what a few hundred of these things could have done in Fargo recently. The prospect of fully automated sandbagging supply lines is easily a game changer for any flooding emergency. Imagine it replacing a wheelchair. Or hell, why not an ATV?
I have to admit, despite the obvious coolness factor, the thing comes across a little creepy. It buzzes like a hornet and looks like some kind of huge headless beetle. And I think anyone would find a large, heavy, powerful robot operating autonomously in their vicinity disquieting at least. Perhaps roboticists themselves would be most cautious. Eric Gradman has more than a few hilarious stories about robots going amok, exploding in his face or driving headlong into a crowd of bystanders. That is symptomatic of the current infantile state of robotics. But the baby is learning to walk. You can watch it yourself.
