The Most Advanced Quadruped Robot on Earth

BigDog is the alpha male of the Boston Dynamics family of robots. It is a quadruped robot that walks, runs, and climbs on rough terrain and carries heavy loads. BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog's legs are articulated like an animal’s, and have compliant elements that absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule, measuring 1 meter long, 0.7 meters tall and 75 kg weight>>>

If they can make a robot walk and not fall why the hell don't they attach the same robot in a smaller form to paralized people so they can walk?

Looks like a Gigantic BUG!

I'd like one that does the work around the house that actually soothes the soul a little more than this thing!

But... pretty amazing!
