This commercial still holds a lot of spirit and heart to it. I really wish we could tap progress on the shoulder and ask for more forwards again...
These used quasi-static walking, where the zero moment point (like a moving centre of gravity) is kept within the support polygon of the footprint. This is what gives them their weird swaying gait and extremely conservative movement characteristics. You could never make a bipedal robot run, jump or respond to large and sudden external forces using this method. It's essentially a balance free movement hack.
