[GZG] Four legs good !!

Hello

Here is a you-tube video of a state-of-the-art four-legged robot: "Big
Dog":
http://www.youtube.com/watch?v=W1czBcnX1Ww

Pretty impressive how it handles broken ground and recovers from stumbling on
slippery ground.

The configuration of the articulated joints on the legs is interesting, which
has no natural prototype, as far as I can see.

Greetings Karl Heinz

I've always rather thought it looked like two people, face-to-face,
carrying a small load. Seldom a recipe for agility...

loved that robot. Even at the worst slip they show, it never goes all the way
down.

It's certainly clever. The way it recovers its balance is certainly
impressive. So far though, it doesn't demonstrate any compelling argument for
legs over wheels or caterpillar tracks. None of the terrain that the video
shows the robot crossing would present much of
a challenge to an all-wheel-drive vehicle. Look at these loonies:

don't think the purpose of this robot is to replace vehicles with wheels or
tracks...I think it is being designed to carry some of the burden that your
typical "grunt" has to haul around these days. So think more pack mule, or
litter carrier, etc.

You must like the earlier version of the robot then.:)

Obviously, the BigDog made the same impression on these fellows. ;->=?
