It's rare that I see a robot that impresses me these days . . . I will have to say that this biped built for the US Army is now at the top of my list.
Watching it's motions, it's clear that BostonDynamics is using the same balancing techniques as with their BigDog robot. This fluidic real-time gait balance controller is how I'd go about building a biped.
Now that the terminator is nearly complete, I guess us humans need to be worried about staying alive . . .
ps - by 'humans', I mean those who don't make robots . . .
