OOOOH yeah that's cool BUT how much is the saddle? Ohhh **** it fell over!! So how much is the saddle aaaand matching helmet???
Just based on a quick look I think the point of this one is the follow ability, and plotting a path through complex obstacles.
The original Big dog might have been quite a few years ago but since then they've had:
big dog no cables
big dog on petrol engine
big dog that runs 30mph
big dog massive payload carrying
big dog that won't fall over / rough terrain
big dog on batteries that follows you automatically.
next: big dog with gun/s?
I guess when they put it all together, that thing's gonna be amazing.
And No you won't see a youtube vid of it. One day the yanks will just "unleash the hounds" on the battlefield.
