Electric motors dont have a lot of "give", like hydraulics do. But yes force-torque controllers can be tuned to be squishier. Someday I think electric motors will be the muscles and we'll have some kind of elastic tendons. For energy efficiency, it seems obvious to harness impact energy in a mechanical spring system, as nature does.
Or just use wheels / a wheel. This whole humanoid thing strikes me as an addiction to old sci Fi stories.
