To be fair Dynamixels are generally worth the money & in this case these specific ones are fairly overkill for what he's doing, these things can hold and smoothly move a ~1.5 kg weight around without issue. Or break your hand/finger/whatever if you're not careful 😉 But yeah, there's no denying they can fetch a pretty penny, its the result of nobody really having a competing product for the past 20 or so years when it comes to size-to-strength ratio (or size-to-speed ratio, depending on model) and amount of control/readout/etc you get for your money. Having said that i feel like they could be a little more affordable these days, but at the same time they probably dont sell a whole lot of the higher range ones so gotta recoup their investment somehow. There's an extremely high likelihood that the (load bearing) servo's in the robots from Disney Imagineering are Dynamixels too.
@@suicidalbanananana yes more size or weight, but cheaper and more powerfull, there are actualy geared cheap dc motors that can for shure overcome those servos. Actualy the control would be based on the sensors and microcontroller.
I think you've pretty much mastered the art of rapid prototyping. The fact that you could get into the real world and stable in 2 weeks is just insane!
Do you like have a team or something, consistently delivering awesome projects and videos on your own at this caliber is so amazingly awesome. Love it!
i watched it in '75, I was six at the time, didn't really understand all of it but it did make me cry when louis died. I've watched it so many times since and it stands out in my mind as more influential on my career as a vfx artist than star wars. @@JaruzelUK
You read my mind, because I was literally thinking this reminded me of Huey, Dewey and Louie a split second before you said it. Now I need to see tha movie again.
with electrolysis you get about 1828L of hydrogen and oxygen per 1L of water, so that creates a very efficient and reliable compressor. so long as you. 1) have a bubbler and mesh filter to prevent gas getting into the system. 2) use pneumatic muscles to fine tune the movement. 3) don't ignite the gasses that are used as rocket fuel. 4) add a condenser to recycle the gasses. 5) keep the system close to the centre of gravity. you can make all pneumatic robots you want, maybe combined it with electrical actuation for more dynamic walkers like an opendog V4 or use the electrolyser and a water wheel as a "heart" to increase runtime for your robots. (please look into this)
I love when you release your videos. I have had to work very late and your videos often come out at midnight for me. It's a welcome surprise to brighten my night :)
Thanks for all the engineering work! I'll take the files and try out to apply some Reinforcement learning to it in the simulation, let's see how that works
Brilliant presentation. I love that you are presenting the measurements that drive the code. You are showing the goals of the code and not presenting the code itself as a solution. That is awesome.
Weird tip you might appreciate. There are these things called nylon rivets which are plastic push rivets that come in all sorts of different sizes (in Metric) and not only are removable (by simply pulling what you pushed), but require significantly less effort in cad as it reduces the amount of nut slots, threads or heat thread insert holes you have to make and instead, all you need is either 2 holes or one hole and a conical cavity for the expanding bit of the nylon thread. The ones you want are called R Type Nylon Rivets. Automotive rivets exist but they all are weird proprietary sizes so you're probably better served with these R Type nylon rivets with tons of different sizes that you can buy cheaply in bulk.
Very impressive demo of a functional concept James. Just one interaction of hardware, and some software experiments to tune a basic algorithm, all in just a couple of weeks! Really looking forward to seeing the hardware design iteration with the extra hip servos. That should really enable many options for future experiments.
When I first saw that video of the droids walking around I immediately thought that they reminded me of birds, and now I realize why, when they walk, their heads move forward and back a little bit, like some birds such as cranes and chickens, this obviously is a form of stabilizing their bodies when walking.
"reflecting the coefficient of the wobblyness of the table" - love it! I also like the rather simple math involved. Biology doesn't use differential equations to walk.
Yes, the chickenlike balancing of the head on the Disney variant is probably helping both with the balance and with any visual system on board (as it does for the chicken).
The real supergenius move here on Disney's part is having three of these units running around together. One or two are a simple curiosity. Three is a squad, a team. It's just the right amount to take advantage of the extra presence numbers give while still being few enough to not overwhelm the audience.
Just Amazing! I'm an engineering student, and when I saw those BD1 Robots, I told myself that I really wanted to do that (Or something like that). But I thought It was impossible or too difficult. Now that I've seen your video I'm very motivated. You are amazing! Blessings
This looks awesome. And not just the technical aspects either, I like how it looks at this stage. Just slap on some fake cameras/sensors on the front to mimic a robot face, maybe some antennas, and you'd be golden. :D
Ура!!!!!!!!! Новый шикарный проект! Восхищение со всех сторон!!!!!!!!! Но неужели еще две недели ждать? Долго(((((((((((((( СПАСИБО!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :-)
13:55 "No fancy PID control", just P! Sounds like proportional control, correcting by a factor that is proportional to the error. I'm taking a course on control systems right now and it's super cool to see the amazing applications it has, sometimes simpler is better.
Trying to make a walking machine with no proper pilot is always challenging. Hard to believe we as humans have similar automated systems. Like gyroscopes to keep us balanced and upright, a biological processor, and several piston like things making up muscles, with an endoskeleton to boot.
I really respect that James mentions “and I’ll get a small commission” it’s a very small gesture but to those who really despise UA-camrs that hide that they make money from sales, sigma energy…
Huey, Dewey, and Louie from Silent Running were the best part of that movies. I loved those little robots! I want robots that look like robots! Not weird human looking ones!
That looks like a load of fun. Makes me wonder if you put a pair of arms on it, could your new robot wander about and pick things up to put in a basket it carries?
It always seemed a little weird humans evolved to walk completely upright. It’s so much harder for us to design bipedal robots, and there aren’t that many animals besides birds that walk on two legs. You would think it would be better to still use our hands to help walk but I guess not.
You know with dynamixels you can not only control the position of the servo but also the speed at which they move and the amount of torque they move with.
I don’t know if anyone else has noticed the similarities but they kind of look like mini ED 209’s from robocop. And I absolutely love that! If only that was explored….. I love your work and thank you! ❤
Won't be too long before "ED" fire Nerf missiles, growls like a tiger on its feet and squeals like a pig on its hip. Then the daughter (if there is one) comes along and totally makes it here pet with a pi ten, or something. Great reference, though. I couldn't remember ED209 for the life of me and knew someone in the comments would remember. It's just a plastic robot chicken. Cool to watch others figure this stuff out but, as I watch these scientists I learn for myself how to deactivate or incapacitate, just in case things get beyond said "Nerf missiles".
You know those videos with AI Learning to Walk on wierd robots. Would be interesting to see a small version of it IRL. Like building a small arena and magnet crane to put it back to the start on failure, then maybe use camera input for carrots based on how long it has gotten forward.
14:58 IMO while functionally this was definitely worse, I think for the purpose of CHARACTER, this was better, the slightly chaotic, high energy stepping is PERFECT for the kinda cutesy behavior a lot of SW droids display.
HI James, been watching you for years. I really hope you follow this through. You are a brilliant maker and could for the first time in tech history, make well formed bipedal robotics accessible to hobbyist. As some others mentioned, I would love to see you use reinforcement learning, and LLMs to assist you. I know you don't need intellectual assistants, but as you mentioned, you dont have a research team. Let the community help you!
Remember that not all surface are flat.... In order you assume to add 2 joints for leg...you Need anorther joint for foot inclination in case of X degree walking surface inclination...
looked up those servos. Holy cow, I didn't know servos could be so expensive!
Those aren't the most expensive, check out Dynamixel Pros, if you can find a price that isn't POA
If u run the motors based on time trigering then u can use a dc motors?

Plus all the production on the video. Gotta give massive props for that.

No it's just me, thanks!
No he doesn't have a team. That's why he is great.
@@jamesbruton that's crazy! your one of the best maker UA-camrs out there!
So he's basically single handedly open sourcing androids for the masses? This is newsworthy at the least!
You can outsource some of the printing to your fans/followers who have large printers so save some printing time
big thumbs up for Huey, Dewey, and Louie. I absolutely love silent running.
Peak 70s Sci-Fi with a message that is still relevant (if not more so) today.
i watched it in '75, I was six at the time, didn't really understand all of it but it did make me cry when louis died. I've watched it so many times since and it stands out in my mind as more influential on my career as a vfx artist than star wars. @@JaruzelUK
Silent Running an awesome iconic film far before it's time .
Yes James it does remind me of Huey , Louie and Dewey 😢
Fattrucker
You are amazing, James. I love to hear your thought process and watch it get turned into something that works.
what a great starting point , I was one of the people who asked about this project so very happy to see a first video.
James I forgot to say you can buy the full 3d model files from do3d search for Imagineering Star Wars Droid Walking

I BEGGING you to recreate the "TANK" robot from generation zero!! It has the same walking style
It's really amazing how much you put into so little time, great robot as always!
Cool! Looking forward for the new features! Amazing how fast you got the basics sorted out!
The Disney ones are cool and adorable. James' one is amazing and sassy.
Sorry James, your analysis is all wrong... there is actually a highly trained hamster inside each of them...
🤮
This is very cute hehe
consume the hamster
Very onbrand for Disney to torture a small animal in the name of entertainment
Makes perfect sense 😂
That was an impressive start to the build. Nice one 😮
Looks really great! The way you designed this with all the bearings ans interlocking shows, how much skill and experience you have. Really impressive!
I love when you release your videos. I have had to work very late and your videos often come out at midnight for me. It's a welcome surprise to brighten my night :)
Thanks for all the engineering work! I'll take the files and try out to apply some Reinforcement learning to it in the simulation, let's see how that works
I'd watch video on that

One dude in his garage made something in a few weeks that probably took a team of Disney engineers years to accomplish. The power of DEI.
I'd never thought of chocking a threaded rod into a drill to get it in place. It's the little things that are the most useful!
EXCELLENT WORK!!!! And HUGE progress!! Only 2 weeks? WOW! You really are THE BEST MAKER here on YT!!
“Coefficient of wobbliness” Ah, yes, of course.
When I first saw that video of the droids walking around I immediately thought that they reminded me of birds, and now I realize why, when they walk, their heads move forward and back a little bit, like some birds such as cranes and chickens, this obviously is a form of stabilizing their bodies when walking.
Suggestion: attack/delay/decay trimming for gait, as a simple framework to control the aggression of foot down/up
"reflecting the coefficient of the wobblyness of the table" - love it!
I also like the rather simple math involved. Biology doesn't use differential equations to walk.
Love the big chonky aesthetic of this channel's projects. The controller is just as cool as the 'bot itself!
I can't believe that by yourself you built such a great prototype in so little time! You are so smart!
I love it! You have done well. I am always taken back by how big you build. Walking without twisting the hips and swinging arms must be difficult.
Yes, the chickenlike balancing of the head on the Disney variant is probably helping both with the balance and with any visual system on board (as it does for the chicken).
This is amazing, and if you make a second one you already have the lion's share of an ED209 for the RoboCop fans.
The real supergenius move here on Disney's part is having three of these units running around together. One or two are a simple curiosity. Three is a squad, a team. It's just the right amount to take advantage of the extra presence numbers give while still being few enough to not overwhelm the audience.
I'm really happy to see another robot project. That has always been my main interest as a maker.
Just Amazing! I'm an engineering student, and when I saw those BD1 Robots, I told myself that I really wanted to do that (Or something like that). But I thought It was impossible or too difficult. Now that I've seen your video I'm very motivated. You are amazing! Blessings
Between you and Aurora Tech, I feel comfortable about humanity's future.
Bravo!
Great stuff as usual. I cant wait to see it with a head on and perhaps some emotive eyes.
Excellent work as always!
I love seeing both Elmo and Pino in your background, because I was involved in the toy safety compliance of those!
If droids were real, I’d want a BD unit as a pet.
Silent Running is such a classic. Made an indelible mark on my soul when I saw it as a kid. As did "Day of the Dolphin"!!!
It’s definately on its edges…. that’s it! Make an ice skating robot next :-) Fun project for the holiday seasons coming up.
I love how this is turning out! it looks adorable. Maybe he can have a name like Bruey?
Such an awesome project, hope you do a BD-1 droid in the future 🙌🏻🙌🏻
This looks awesome. And not just the technical aspects either, I like how it looks at this stage. Just slap on some fake cameras/sensors on the front to mimic a robot face, maybe some antennas, and you'd be golden. :D
i like it when the smart british man says lumps
Ура!!!!!!!!! Новый шикарный проект! Восхищение со всех сторон!!!!!!!!! Но неужели еще две недели ждать? Долго(((((((((((((( СПАСИБО!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :-)
Your prototype immediately has me imagining a little toolbox buddy to follow you around the shop. Someday!

Very cool project James. Cant wait to see the next phase.
When I first saw the video from Disney, all I could think about was I can't wait till James does this. Here we go...
Thank you James!
Nice. Yes, like the Silent Running Robots.
Brilliant and a Silent Runnings reference - one of my favourite films!!!
Coefficient of Wobblyness is a turn of phrase I didnt know I needed until now.
I was also thinking it looked like the robots from Silent Running. All you need is a little watering can. Great project.
Trying to make a walking machine with no proper pilot is always challenging. Hard to believe we as humans have similar automated systems.
Like gyroscopes to keep us balanced and upright, a biological processor, and several piston like things making up muscles, with an endoskeleton to boot.
Definitely reminiscent of Silent Running's lovely droids... maybe they could be a future project?
Possibly, the legs are quite far apart though which makes it tricky
I really respect that James mentions “and I’ll get a small commission” it’s a very small gesture but to those who really despise UA-camrs that hide that they make money from sales, sigma energy…
Really like the new project. I'm really excited to see how it's gonna turn out!
the disney ones are so precious!! i loved your version too but theirs are just so cute
“Not bad for something I just threw together” is the biggest flex
Certainly not 'Silent Running' but definitely 'Noisy Walking'.....cheers !!
was about to go to bed when i saw this video posted. xD love your content james.
Excited to see more development of this. I can see these guys working in factories.
Yes! Please see it through to the full design with the head!!!
Very very cool project! Please keep it going! want to see the finished robot!
I love the thought of making a droid like this love the video man
Please put on the eyes you made for the Arduino tutorial. It would be hilarious to see that!
Huey, Dewey, and Louie from Silent Running were the best part of that movies. I loved those little robots! I want robots that look like robots! Not weird human looking ones!
Yes, James, it does remind me of Huey, Dewey and Louie.

"Whoops!" 😄 Great job managing expectations, there.
The Disneyworld versions dont just use IMUs with a PID, they also use Reinforcement Learning.
Silent Running made me cry - great robot though
I don’t know if anyone else has noticed the similarities but they kind of look like mini ED 209’s from robocop. And I absolutely love that! If only that was explored….. I love your work and thank you! ❤

This would be a great design for inside the legs of an R2D2 build. It has the same look as when he walks.
Looking forward to the next one! I hope you do a whole video on the head, and adding some ears/antenna for extra emotional response!
Amazing build! Now for the next big project; building Vasco from Starfield!
some weight hung below the connection point of the hips, between the legs, may add some inertial stability as well, by lowering the center of gravity.
You know those videos with AI Learning to Walk on wierd robots. Would be interesting to see a small version of it IRL.
Like building a small arena and magnet crane to put it back to the start on failure, then maybe use camera input for carrots based on how long it has gotten forward.
i think disney modeled their kinematics after chickens
16:35 The coëfficiënt of the wobbeliness of the table 😍
Stop short selling yourself, you've got skills man!
Pretty sure if James had the money and the engineering team of Disney, we'd be living in an Asimov future already!
You're accidentally building ED-209 ;)
Epic work
14:58 IMO while functionally this was definitely worse, I think for the purpose of CHARACTER, this was better, the slightly chaotic, high energy stepping is PERFECT for the kinda cutesy behavior a lot of SW droids display.
A pivot servo mounted in the hip aera could assist in controlling balance.
been waiting for you to release a video about these!!
I'd love to see an RC BattleMech. The clans have several reverse jointed walkers like the iconic Mad Cat.
Great work again. I'm looking forward to next video!!
It would be really cool to see you create a robot like this and then create an AI to make it teach itself how to walk.
And drop a large language model as the interface, boom we bot c3p0
Yay for the "Silent Running" reference!
Now we are back to really useful projects 👍
Wow you figured out it's movement exactly.
HI James, been watching you for years. I really hope you follow this through.

Those lumps, those lumps, those lovely robot lumps!
Awesome work! Very impressive design in such a short time!
Remember that not all surface are flat.... In order you assume to add 2 joints for leg...you Need anorther joint for foot inclination in case of X degree walking surface inclination...
