    "Big Dog" Quadraped Robot

    The video on this page is pretty cool, but sort of weird at the same time.

    After watching that video, then you should see this one. Made me laugh.

    I have seen this before and every time I watch it I am left with the same sort of mixture between unease and pity? Now I know how crazy it is to pity a robot but when the guy kicks it in the side it evokes the same sort of response in me that I would feel at watching somebody do that to a dog or horse. How insane is that?? I guess there must be something deep rooted mentally that equates walking on legs with some level of consciousness in the walker. Or maybe I'm just wierd?

    Ian, I'm weird too then

    It is really a cool thing, but yeah, I get a creepy feeling watching it and felt it should kick those guys back

    I like it.

    Of course, if I'd been on the design team, it would have had twice as many legs, and the optical sensors on the front would be the size of soccer balls.

    Probably make people a bit less likely to try to kick it.
    Where are we going? And what am I doing in this handbasket?

    "Big Dog" Quadraped Robot

    Maybe I'll get laughed at here , but don't you think the guy kicked the robot to show how stabile the machine is? I thought so and was amazed at its ability to recover and not go down.

    Such things are a comin' in our future.

    Thanks Vaughn.

    Aloha, Tony

    Tony, I'm sure you're right about them kicking the robot to show its stability. (They do it in other videos, too.) Pretty amazing programming to enable it to stay upright. But, like the other guys mentioned, I get an irrational feeling of pity seeing it get kicked, and general creepiness seeing it walk.

    I'd laugh my tukuss off if the dog after being kicked
    would come back and kick the crap out of the guy that
    kicked him!

    That guy better hope that that dog never gets a fang upgrade!

    I'm pretty sure that was the point. What I want to know is, when (not if) it does get knocked over, can it get back up on its own, especially when fully loaded?

    That things agility is surely AMAZING. Absolutely amazing!

    I watched the video after reading the comments about the "kick" expecting meanness or violence. After I saw it it was very apparent to me that it was a shove as opposed to a kick. I took it as a shove rather than a kick so that the guy could stay out of the way of the flailing feet/legs.

    BUT, what did really creep me out was the similarity it had to a fly. With the packs on and the shape and articulation of the legs, it reminded me of the original version of "The Fly". Those legs on the robot were SO similar to the legs of a fly and the front packs as eyes, ugh.....(shudder, shudder).

    On another note however, did that machine evoke in anyone else the images of the futuristic war machines in Sci-Fi movies? Among other movies, the AT-AT walkers, AT-ST walkers and such from Star Wars?

    Hmmmmm.............

    Me too - looks like a walking animal

    I thought I was the only one who instinctly felt that way Ian. I am speculating, but the engineers look like they did recorded motion studies of 4 legged animals to get the control system design. If they dressed that machine up in some scary looking acessories, that buzzing engine and animal looking gait, it would scare the life out of someone in the woods.
