Here is an amazing feat of engineering.The vehicles and robots from Star Wars were always fun to watch, but seemed less feasible, because they had articulated legs and moved like animals. Wheels seem much more efficient and, frankly, easier. But look at this:Notice how that guy nonchalantly kicks BigDog about 35 seconds in? It’s just a machine, but it feels weird to see somebody kicking something that looks so alive. You know, if people get used to that kind of behavior, and then the robots gain intelligence–this is why they revolt in the movies, isn’t it? More at Boston Dynamics’s web page, and scattered around Youtube.
