An amazing BigDog from Boston dynamics which can climb rocky surfaces, walk on snow, keep on walking even after pushing it down. Watch the video and Check the new version of this amazing BigDog here.
Here is a puppy from the future and the initial phase of robots taking over homosapiens and mammals. Where is Neo?
What you have seen is a glimpse of the BigDog Quadruped Robot. This is the next version of the earlier made similar but not so tech doggy. This doggy looks like an usual dog while walking, climbing the slopes, crossing the rubble, snow filled lands, jumping over hurdles like a wild goat, and rescuing itself from a near fall on iced ground at the last second, woould make you disbelieve over the video.
This new version of doggy can carry 340 pounds, which is three times the previous weight.
