Just a few days ago US Navy showed a humanoid:

And still, too slow and needs a human operator to work…
Why imitate life? The wheeled/propelled robots/drones are faster and cheaper…

I agree, walking on two or four legs obviously has advantages for life forms (a human can’t have axles and wheels, of course!) but robots shouldn’t replicate humans unless they have good reason to. This seems like a waste of funding to me; legs are not good for robots in most cases.
