The legs to surpass Metal Gear!
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.
Let us know your design, we are curious!
@@dynamiclocomotion Sorry, I'm still a wannabe - I'm working on quite a crude walking mechanism for a small weight class gyrowalking combat robot, but I have nothing good to show so far.
@@isaacgraphics1416 Don't be so harsh on yourself, everyone's gotta start somewhere and there's nothing wrong with being a wannabe! That's the great thing, WANTING to BE. I hope in these 3 months you've made some sort of progress, as any progress is already amazing.
@@isaacgraphics1416 i suggest you to check out the "Gyrubot" , it uses four gyros and is very stable despite having a weird leg configuration , i'm pretty sure that if you combine the stabilization of the Gyrubot and the legs of the Birdbot your robot will be extremely capable
Absolutely terrifying, imagine that thing sprinting towards you at night. Thanks for the nightmares
"prancing towards you" would be more appropriate for that gait.
Mechwarrior becomes one step closer
Clever tendon designs there! Solid research.
I can't be the only one seeing a kickboxer running backwards while horse-kicking?
I cant wait to see these on a drone🤩
Please ! Someone make a robotic velociraptor. That's my child dream !
X2
I will settle for a robo chicken
“‘Ooh, ah,’ that’s how it always starts. But then later there’s running and screaming.”
I just picture a Google Search result that's like
Did you mean: *_nightmare_*
Tip: make the claws and teeth out of soft silicone. Would still look good, but far less stabby.
Accurate material analogues are nice and all, but please have a thought for the people who have to clean up after the inevitable happens.
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.
Just shows that dinosaurs really were masters of all domains. They could swim, fly, crawl, run, glide, climb ... they're a good model for any kind of locomotion, I'd imagine.
@@jasonraines7629Can they do the nutbush?
@@Relatablename and the charleston.
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.
Reminds me of those things from Star Wars
Time for some Battletech mechs
*TIMBERWOLF INTENSIFIES*
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.
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.
Notice how the "chicken leg" is was even used by quite large animals like T-rex and said animal could weight more than 7 tons , meanwhile Gigantophitecus was a Big primate that has a more humanoid forms yet it didn't past the ton of weight
Avians have a few(maybe 150) million years more of refinement, compared to the awkward mammal bipeds we are.
Beautiful movement
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
NO WAY TWO OF MY MOST FAVORITE THINGS
Very promising design
Featherless ✅
Biped ✅
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.
Now, we can finally build an AT-ST.
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!!
2:38 looks like a dude holding something, maybe a gun, running backwards, and the real-time footage is super scary. Imagine it being three stories tall and barking orders to stay inside lol
Can't wait to have my takeaway delivered by a bird robot
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??
Ooooh.. I can learn something here.
it looks very trex
A weapon to surpass metal gear
The legs' motion is pure perfection
Hmmm... I wonder how well that would work on a Cassie bot. Similar leg shape plus machine learning.
This is so cool omg
YES MECH WARRIOR!
brilliant
One step closer to war mechs yeah!!!!
FINALLY
Star wars walkers are coming.
hell yeah dinosaur
Perfect design for BD-1 from Jedi Survivor!!
Ooh Frittata!
No Mans Sky!!!
This might also work for the hind legs of a quadrupedal robot.
Also, that Timberwolf/Mad Cat Battlemech is looking a lot more possible.
that's what i was going to say! can't wait to see mad cat :)
If not the _Mad Cat,_ then definitely the _Locust._
@@TustlePlays that would be fun to see
Your childhood dream can turn into someone's nightmare.
I was thinking the same thing. Maybe when the rear legs go on the Mini Cheetah I'll replace them with something like this
ED-209 borning
Also looks like the front legs of a cheetah.
Build me a pair large enough to attach a hut on top of so i can pretend to be baba yaga, also a flying cauldron or mortar and pestle would be great too please.
I like this video...👍
Warframe Moa: beginnings
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.
In the future, people are likely to ride animal machines robots
"Metal... gear?"
Why is the left leg is swinging higher than the right?
Super excited to get trampled by an ostrich bot.
Bird up!
Amazing work on this!!! Reminds me of BD-1 from Star Wars 😄
Thank you. I was just looking up BD-1.. and I see the little guy has segment-feet. A good start!
Watch out! AT-ST on your 6!
Metal Gear Gecko's LET'S GOOO
am i the only one who just sees a humanoid robot running backwards ?!
Does anyone else get Robocop ED-209 vibes?
*LOADERBOT from Borderlands 2 and tales from the borderlands
OMG we can have a scaled down version of Robocop's ED-209 with these legs!
Scaled up version of these legs are 1.75cm tall , weight roughly 75kg and can carry over 2 tons , and that is for each leg
@@ulforcemegamon3094 1.75 m you mean?? That's still freaking amazing strength. These could be great all purpose industrial warehouse bots.
Ah wanna' build one!
Hi Mike G; you can! We provide CAD files for non-commercial use; search for Edmond on our dlg.is.mpg.de/publications/bb01 page
Four leg tiger 🐅 from masters of the universe robot complete with armor a paint 🎨
Thanks for proving just how incredibly elegant biological muscles are and how absurdly backwards these mechanical approaches are.
Yeah , the difference between a leg like the one of spot and this leg is abysmal, is crazy the amount of difference there is
Amazing!!!! I play on studying electrical engineering but stuff like this makes me rally wanna study mechanical instead, shame im so bad at physics btw which program do you use at 1:42?
i'm pretty sure a robotics program would teach you a combination of both, as well as programming, when i looked into taking it over 20 years ago they taught all aspects of robotics so you would be able to design, build, wire and program your own robots.
CAD program? Solidworks. Many other programs support similar features.
@@dynamiclocomotion ah thanks.
When you gonna add claws?
9 points on energy-efficient 1 point on maintainability.
It is really easier to maintain many servos with many moving parts compared to a bunch of cables thought?
@@ulforcemegamon3094 just take a look into a old automated production line.
now make a t-rex
Both walking forms for future mechs have been developed.
Specially when you consider how easily scalable these legs are
“Birds move their legs unlike humans.”
*moves legs*
Am…
Am I a bird?
No, you are a mutant human, and therefore must be eradicated, if i had working legs i'd get ya.
hello mr. Ed-209
Yes, we're that much closer to making an AT-ST
One step closer to Mechwarrior!
could easily be adapted to a quadruped design
Now scale it up ten times this size and fit missile launchers, Clan Steiner demands it.
Mechwarrior when?
I have a small question.
Since the head bopping seemed kinda severe in the video, would it effect the energy efficiency?
Or since the head bopping moves in a rotation cycle, it doesn’t effect the energy efficiency?
Head seemed stable to me not sure what you mean.
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.
BD-1
Adding gears onto the leg for leg retraction was actually first proposed by Festo's bat flying wing structure.
there have also been several working ornithopters built in universities over the past few decades, i would imagine they would also have gears to retract the legs, or landing gear, whatever they chose to call them
Foundational tech for an AT-ST from Star Wars
Now make it 50x bigger
0:01
Does it balance on its own
Not yet sideways. We are working on fixing that ^^
metal... gear?
Gonna make BD-1 with these legs
Real life Zoids, here we come!
Now make it bigger, slap a cabin and some laser guns at it and we have our first AT-ST 😂
Did these guys just invent the walking legs for an AT Corp Irving "Gekko" walking Antipersonnel tank? Man, we really aren't all that far from the world of Metal Gear Solid 4 after all.
If looking at it backward in time it looks like a 100m sprinter...
let’s put a house on it
We should put a car on it
is it being built by a company or a hobbyist?
We are a research group at the Max Planck Institute for Intelligent Systems (Germany, Stuttgart).
@@dynamiclocomotion understood. what are good first steps for someone to start learning about robotics and trying to build most basic ones at home?
a weapon to surpass metal gear
at 0:44, what software is used to make those animated 2D drawings?
Based on scripts in Matlab, for the robot's leg and tendon motions.
@@dynamiclocomotion sorry I mean 0:47 is it also done in Matlab?
I wonder if this mechanism could be adapted into a walking assistant for humans.
Perhaps, but hard to beat the simplicity of wheels.
@@peytonmac1131 wheels are pretty easily defeated by stairs, steep slopes, wet ground, rocks etc...
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."
the left leg is extending too quickly.
How much does it weigh
1.8kg
cool, now make AT-ST from this
cual es el circuito eléctrico que utiliza? utiliza arduino?
12 V power supply. Arduino and Raspberry Pi.
@@dynamiclocomotion pero se pueden encontrar los diagramas y la codificacion del programador?
@@526andress si , en el link de la descripción donde están los CAD también se encuentra los códigos
Metal gear....
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.
