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 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 :)
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
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.
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
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)
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).
Ура!!!!!!!!! Новый шикарный проект! Восхищение со всех сторон!!!!!!!!! Но неужели еще две недели ждать? Долго(((((((((((((( СПАСИБО!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :-)
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
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.
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.
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.
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
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.
Nice!! Just a heads up you might want to do some contrast adjustment for the graph @ approx 7:51 I noticed it was showing as blank white until I tweaked my display. I think the lines are just too thin and the background pixels overtook the graph lines in my case. (1080p large scale display if that helps) love to see the new work at any rate James!
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.
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.
"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.
Looking at the Disney ones shape it looks like the batteries or a counterbalance is between the legs to drop the centre of balance and aid with stability.
What would it look like if there was a flywheel with a one-sided weight in the top center? You would only have to time it with the movement and could thus compensate for the oscillation in the X axis. So when the right foot is in the air, the weight is on the left etc. etc.
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?
Hi James, I’ve been a big fan for several year now. Could you create the complete Droid you saw at Disney, like you did the BB8 and other droids? I’d love to see that. Keep doin what you do!
I'm not sure if this would make any sense, but I think you could use some kind of differential mechanic to allow some hip movement, while keeping the torso mostly vertical. If you can connect it to the upper servos then it would be completely mechanical, without the need for extra motors or electronics.
No one remembers Huey, Dewey, and Louie, or Bruce Dern for that matter. Nice that the originals were Disney characters, though. Have you considered a powered, inverted pendulum in the upper body for balance? Can the batteries be mounted in the feet to lower the CG?
Ideally it wants the majority of the mass higher up - a stick with a mass on the top is easier to balance on your hand because it doesn't fall over so quick. If the mass is in the feet then it'll take more force to move the feet quickly to balance as it walks.
Fantastic! Please keep going! Those WDI robots are so appealing, it would be cool to see your version of them, how close you can get to WDI's big budget R&D!
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?

@@nestorovski1993 Technically yes, but you'd end up with more weight/size, more power consumption & less control.

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 😂
I think you've pretty much mastered the art of rapid prototyping.

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
ありがとうございます！
Thanks!
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.
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!
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 :)
I BEGGING you to recreate the "TANK" robot from generation zero!! It has the same walking style
Looks really great! The way you designed this with all the bearings ans interlocking shows, how much skill and experience you have. Really impressive!
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
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

EXCELLENT WORK!!!! And HUGE progress!! Only 2 weeks? WOW! You really are THE BEST MAKER here on YT!!

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.

Thank you James!

Suggestion: attack/delay/decay trimming for gait, as a simple framework to control the aggression of foot down/up
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.
Love the big chonky aesthetic of this channel's projects. The controller is just as cool as the 'bot itself!
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!
i like it when the smart british man says lumps
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.
I love how this is turning out! it looks adorable. Maybe he can have a name like Bruey?
“Coefficient of wobbliness” Ah, yes, of course.
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 can't believe that by yourself you built such a great prototype in so little time! You are so smart!
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

If droids were real, I’d want a BD unit as a pet.
Very cool project James. Cant wait to see the next phase.
Great stuff as usual. I cant wait to see it with a head on and perhaps some emotive eyes.
was about to go to bed when i saw this video posted. xD love your content james.
Nice!! Just a heads up you might want to do some contrast adjustment for the graph @ approx 7:51 I noticed it was showing as blank white until I tweaked my display.

Such an awesome project, hope you do a BD-1 droid in the future 🙌🏻🙌🏻
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!
It’s definately on its edges…. that’s it! Make an ice skating robot next :-) Fun project for the holiday seasons coming up.
Brilliant and a Silent Runnings reference - one of my favourite films!!!
been waiting for you to release a video about these!!
Very very cool project! Please keep it going! want to see the finished robot!
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
Yes! Please see it through to the full design with the head!!!
Excellent as always James!
I'm really happy to see another robot project. That has always been my main interest as a maker.
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.
Great work again. I'm looking forward to next video!!
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!
Nice. Yes, like the Silent Running Robots.
This is amazing, and if you make a second one you already have the lion's share of an ED209 for the RoboCop fans.
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.
Between you and Aurora Tech, I feel comfortable about humanity's future.
Bravo!
great work. Really impressive James
I love the thought of making a droid like this love the video man
Awesome work! Very impressive design in such a short time!
Well done....
I am very impressed with your project. Thank you for sharing.
"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.
Please put on the eyes you made for the Arduino tutorial. It would be hilarious to see that!
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
Pretty awesome looking
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"!!!
16:35 The coëfficiënt of the wobbeliness of the table 😍
You sir, are incredible
How do you put out so many good videos and projects?
Work hard I guess
A pivot servo mounted in the hip aera could assist in controlling balance.
Looking at the Disney ones shape it looks like the batteries or a counterbalance is between the legs to drop the centre of balance and aid with stability.
Possibly, although a stick with the mass higher up is easier to balance because the top moves slower and it doesn't fall over so quick
Batteries are in the back of the Disney droid, in some of the vids you can see it, its been identified as a Unitree Go1 24v pack.
i think disney modeled their kinematics after chickens
You are amazing! 👍
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.
What would it look like if there was a flywheel with a one-sided weight in the top center? You would only have to time it with the movement and could thus compensate for the oscillation in the X axis. So when the right foot is in the air, the weight is on the left etc. etc.

Hi James, I’ve been a big fan for several year now. Could you create the complete Droid you saw at Disney, like you did the BB8 and other droids? I’d love to see that. Keep doin what you do!
What about putting a gyro into the body portion to help with the counter balance
I considered it, but it's quite a lot of mass and extra power to carry about.
Fantastic work!
I'm not sure if this would make any sense, but I think you could use some kind of differential mechanic to allow some hip movement, while keeping the torso mostly vertical. If you can connect it to the upper servos then it would be completely mechanical, without the need for extra motors or electronics.
Your prototype immediately has me imagining a little toolbox buddy to follow you around the shop. Someday!
Can you update Doc Ock
“Not bad for something I just threw together” is the biggest flex
Will you ever return to your ANDOR B2EMO droid build?
It would be awesome to see more of B2EMO
Waiting for Season 2 maybe
No one remembers Huey, Dewey, and Louie, or Bruce Dern for that matter. Nice that the originals were Disney characters, though. Have you considered a powered, inverted pendulum in the upper body for balance? Can the batteries be mounted in the feet to lower the CG?

I do. The demise of Drone #3 is still one of the saddest scenes involving robots in any movie I know.
Fantastic! Please keep going! Those WDI robots are so appealing, it would be cool to see your version of them, how close you can get to WDI's big budget R&D!
really nice, come such a long way.
I want one
Excited to see more development of this. I can see these guys working in factories.
Cool stuff as always! 👍
how many times can he make the same legs?
Coefficient of Wobblyness is a turn of phrase I didnt know I needed until now.
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...
You really are my spirit animal, Bro.
Love you channel.
Now we are back to really useful projects 👍
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
