New developped horse-like robot in US army

Just watch it in internet, impressive.
the robot walks just like the real horse and could rejects the external disturbance such as push or kick by a mature male.
Just share with you guys.
Anybody gets an idea what control method used by them to make the robot keep balance perfect like real animals?

just wondering what are they using to actuate the robot?? kind off to noisy for a robot.
Not really sure on what is the controller they used, it can be as simple of simple programming, where the input is measured in an impact sensors, and the actuator is activated simply based on programming. it can also be as complicated of using fuzzy controller, GA or even MLP....
simple fuzzy controller will not be able to do this.
as the video viewed during Dr prahald's lec, all the showing Humanoid robots are not able to walk very stable.
Is it because the electronic creature having four legs such that it is much easier to have a stable motion?
Do you all know then technique of recording 3D game object. I remember seeing the mkaing of the horse by sticking color ball(normally white) and the video cam record the horse movement. Using image processing a 3D object of the horse can be reproduce. I wonder if the same method can be use so a more "real" movement can be mimic

I'm just wondering wheather the robot-horse is remotely controlled or is going by its own will. It is really impresive to see such a robot-horse. Due to its ability to run in different terrain and climb a small hill, it has a lot of potential as a replacement for SUV maybe, or acts as a spy for military use. Of course the noise level should be lowered if it ever used as a spy.
being spy is a good idea actually.haha
in the battle, it could deliever all the necessary tools, food, medicine to the front line.
of course, respect to those above, it is not just assistive any more

Legs are more stable than wheels? I doubt that. I am just wondering where the sensors are placed at and what kind of information is sent back to controller.

Wow, this sure is unique for a robot to be able to achieve such stability and it is an interesting video. No I don't think they use a simple controller too, I suspect it could be fuzzy because at least with a fuzzy controller, you have more options instead of just a simple 3 variables in PID. Also, I suspect it achieves more stability too in the 4 legs it has compared to the normal 2 legs we see.
