Re: legs

Look at most hooved creaturs and you'll see the legs don't waste a lot of space and weight. These legs have the minimum required to be functional. Anything else would just be window dressing.

Yes, BigDog is impressive, it seems tio be following the guy in video nicely...but what's up with the legs in all cases? animal kingdom is using much more powerful legs!

Saw the video, wildcat robot looks quite real in some shots. But what would be its function. Also wondering why the legs of wildcat are so lean compared to its body. Is it battery operated.

This version is only seen on a flat surface, but the Bigdog and Ls3 are much more robust and can be seen marching through some pretty rugged terrain

I think bigdog and LS3 are clear 100% evidence that their system works in unpredictable and rough terrain. 

 

Here's LS3 on moderately uneven terrain, including some spills down embankments. It also shows a bit of the navigational path system. 

 

Now imagine that this thing could go into a full sprinting gait when it hits a fairly smooth path!

>> However, just like everything else that runs on legs, it will obviously be slower in unpredictable circumstances. 

The big question is whether it can actually work in an unpredicatable environment. But they have a decent work but we are still years away from the real deal

Very commendable. Will be good if it can climb the mountains of Kabul.

Gotta Crawl Before You Can Run

This is great progress. Sure it is running on a flat surface, but you have to crawl before you can walk (or run rather). Military uses aside, this is really a technology foundation for animal and/or human like assistance robots - think of the movie "iRobot". We may even see robotic pets like dogs, cats, perhaps even horses. Maybe someday replace the bulls and horses at rodeos removing the life threatening aspect? Could replace the fox in the English "fox hunt"? Could be used as horse riding training vehicles - much safer for children to learn that way? No more greyhound racing using real dogs - contestants compete instead with their latest greyhound robotic dog? I wonder why they used a combustion engine (I'm guessing some modified motorcycle), instead of an modified electric motorcycle. Maybe that's what they will do next?

Quite impressive

Interesting they are using the gasolin engine for a powerplant (hydrolics?) - usually proof of concept doesn't need to deal with a "practical" power source.  This thing could probably have a large range using gasoline.  It was nice to see the gallop and trot - any dressage ;)  We have seen others climb stairs and clear obsticles although who really knows what it's capabilities/limitations 16mph is pretty quick on legs.  That is quite a large mass to move, balance and even turn - very, very impressive - and it seems to have all the logic on board - it would be nice to know how autonimous it is.  It also looks like they could easily tuck the legs, or have it in a cart for transportation.  Very impressive demonstration.

I could be wrong here, but I think the goal is to have something that can transisiton from sprinting on even terrain to navigating things where wheels don't work well, Imagine this and bigdog combined.
