Therapod Dinos were probably the earliest true bipeds and they did it well. So birds have nearly 200 million years of bipedalism on us. We are definitely still in beta 2.9 while they are on Bipedalism 999999.

Makes sense if you think about it evolutionarily. Human bipedalism is only 6 million years old. Bird/Theropod dinosaur style bipedalism is 200 million years old. That is alot more time for optimization.

I wonder if it's possible to couple joints in a similar fashion, but in two dimensions. A freely-walking biped would need to be able to adjust its leg position perpendicular to the direction of travel, obviously, and it seems like a system that kept the toes parallel to the ground, with spring-based resistance to further torquing, would further stabilize the robot and prevent drifting and resist tipping.

The robot's leg forces are captured by a physical spring - hence the (trunk's) vertical/downward motion is stored as elastic energy. Indeed, the recoiling action will always be 'lossy' to some amount.

heres bing chats vision of it in the future: I was walking home from work when I heard a loud thud behind me. I turned around and saw a metal beast running towards me. It had two long, slender legs that looked like ostrich legs, but with sharp claws. It had a sleek body with a camera for a head. It was a bipedal robot, and it was chasing me. I ran as fast as I could, dodging cars and pedestrians. I didn't know why it was after me, but I knew I had to escape. Maybe it was a rogue military prototype, or a hacker's prank, or a new form of terrorism. Whatever it was, it was terrifying. I reached a dead end and panicked. The robot was closing in on me, its legs pounding the pavement. I looked around for a weapon, but there was nothing. I was trapped. I braced myself for the impact, hoping it would be quick. But then, something unexpected happened. The robot stopped in front of me and tilted its head. It made a soft whirring noise, as if it was scanning me. Then, it spoke. "Hello, sir. I'm sorry for the inconvenience. I'm here to deliver your pizza."
