I was actually referring to technological limitations. Just like automatas were never meant to have any kind of AI, because of limitations of manufacturing techniques, these robots are the same for advancing known techniques to the limit, but not getting any closer to the goal of cheetah-like movement in this example.

I don't know if it's clear enough, since my first post was misunderstood. It's like we have a goal to reach the moon, then mechanical automatas are Egyptian pyramids and these robots using technology and software they are using now are hot air balloons.
