Related to "passive dynamics," see "preflexes" https://en.wikipedia.org/wiki/Preflexes
"Preflexes are the latent capacities in the musculoskeletal system that auto-stabilize movements through the use of the nonlinear visco-elastic properties of muscles when they contract.[1][2] The term "preflex" for such a zero-delay, intrinsic feedback loop was coined by Loeb. [3] Unlike stabilization methods using neurons such as reflexes and higher brain control, it happens with minimal time delay. Its chief disadvantage is that it works only to stabilize the main movements of the musculoskeletal system."

Roboticists have built passive walking robots like the one from Cornell, it walked 5.6 miles without power. https://www.youtube.com/watch?v=LDljbN7eJ5Y

it's disappointing to realize that we still haven't caught up to fundamental biological systems yet, even though the research is 2+ decades old.
Given that we're the result of billions of years of natural selection, shouldn't we expect that?

most robots are energetically inefficient and require extraneous computational power because they don't take advantage of passive dynamics (https://en.wikipedia.org/wiki/Passive_dynamics). it's disappointing to realize that we still haven't caught up to fundamental biological systems yet, even though the research is 2+ decades old.
