Absolutely incredible design. This fluidity of motion isn't something I'm used to seeing with so few servo motors. I'm definitely going to take inspiration from this in my designs in future.

Brilliant. Irony is a bird model for a terrestrial locomotion here. Yes, ostrich is an excellent sprinter & much to show alongside Guinea fowl etc. Bipedalism is adopted by a very large group of land animals. One of the fascinating evolutionary transitions is presented here.

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.
I cant wait to see these on a drone🤩
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.
Beautiful movement
Reminds me of those things from Star Wars
Ever since I moved out to the country, I have said when talking about robotics and mecha, that the best for of bipedal locomotion to imitate mechanically, is not the human form, but that of a chicken.

Avians have a few(maybe 150) million years more of refinement, compared to the awkward mammal bipeds we are.
Hmmm... I wonder how well that would work on a Cassie bot. Similar leg shape plus machine learning.
Interesting way to do it and it seems very logical now that I see it. Keep it up I think you've got something worth while.
fantastic design
Very promising design
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.
wow, this is so cool!!
NO WAY TWO OF MY MOST FAVORITE THINGS
Nature will always show you stunning things if you look close enough. How many million of years do you think this near reflexive efficient gait used by all the dinosaurs to modern day avians took to evolve??

Why is the left leg is swinging higher than the right?
Its cool how we are figuring out why nature favours certain solutions and then can use the principles in out creations. And why not? Nature has had millions of years of trail and error to filter out what tends to work well in a given situation.
This might also work for the hind legs of a quadrupedal robot. Also, that Timberwolf/Mad Cat Battlemech is looking a lot more possible.

The legs' motion is pure perfection
Ooooh.. I can learn something here.
Nice, though the balance does seem rather off...the leg reaches too far forward, doesn't go back quite far enough, and the body looks like it's tilted back too much. Though these are all 'tweaking' things, the basic design is excellent.
Can't wait to have my takeaway delivered by a bird robot

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.

a weapon to surpass metal gear
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."
I'd like to see 1 shot of the thing walking at full speed. Slo mo is good for demonstration but comparison between the shots is much more elucidating.
