A number or people have sent me various videos of the new Star Wars Droids walking around Disney’s Galaxies Edge theme park. These are smallish bipedal Droid characters which are a bit like BD-1 but kind of bigger and with bigger joints, because they aren’t fiction.
The robot I’m going to build in this video will only have four motors. I’m going to ignore four of the hip joints as well, and also simplify the legs so we just end up with something that’s a bit like tipping a box onto its corners without its body being able to translate directly sideways. I am however going to walk on feet with edges to pivot sideways, so no big feet this time around. If this works ok then I can move on to build something more advanced in a future video with a head and the missing joints.

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
Wow, you weren't kidding. Dynamixel xm540-w270-t servos, $420 each
If u run the motors based on time trigering then u can use a dc motors?
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.
@@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.
The fact that you could get into the real world and stable in 2 weeks is just insane!
Plus all the production on the video. Gotta give massive props for that.
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!
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 CZcamsrs 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
Cool! Looking forward for the new features! Amazing how fast you got the basics sorted out!
You are amazing, James. I love to hear your thought process and watch it get turned into something that works.
Silent Running an awesome iconic film far before it's time .
Yes James it does remind me of Huey , Louie and Dewey 😢
Fattrucker
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 :)
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.
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
Such an awesome project, hope you do a BD-1 droid in the future 🙌🏻🙌🏻
It's really amazing how much you put into so little time, great robot as always!
EXCELLENT WORK!!!! And HUGE progress!! Only 2 weeks? WOW! You really are THE BEST MAKER here on YT!!
I am very impressed with your project. Thank you for sharing.
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!
Thank you James!
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.
Very cool project James. Cant wait to see the next phase.
Really like the new project. I'm really excited to see how it's gonna turn out!
great work. Really impressive James
Great work again. I'm looking forward to next video!!
Excellent as always James!
I can't believe that by yourself you built such a great prototype in so little time! You are so smart!
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
been waiting for you to release a video about these!!
Love the big chonky aesthetic of this channel's projects. The controller is just as cool as the 'bot itself!
I'm really happy to see another robot project. That has always been my main interest as a maker.
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).
Awesome work! Very impressive design in such a short time!
Great stuff as usual. I cant wait to see it with a head on and perhaps some emotive eyes.
Very very cool project! Please keep it going! want to see the finished robot!
The Disney ones are cool and adorable. James' one is amazing and sassy.
Brilliant and a Silent Runnings reference - one of my favourite films!!!
Yes ! very interested in this project ! Love building droids.
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
Fantastic work!
Between you and Aurora Tech, I feel comfortable about humanity's future.
Bravo!
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.
was about to go to bed when i saw this video posted. xD love your content james.
I love the thought of making a droid like this love the video man
Excited to see more development of this. I can see these guys working in factories.
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!
Pretty awesome looking
You sir, are incredible
Now we are back to really useful projects 👍
really really cool project!
You really are my spirit animal, Bro.
Love you channel.
Ура!!!!!!!!! Новый шикарный проект! Восхищение со всех сторон!!!!!!!!! Но неужели еще две недели ждать? Долго(((((((((((((( СПАСИБО!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :-)
the disney ones are so precious!! i loved your version too but theirs are just so cute
Cool stuff as always! 👍
I
Good work 👍
I remember the 3 robots you mentioned.
Nice film by the way
really nice, come such a long way.
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
I love this project
You are amazing! 👍
Yeah this is awesome
I love how this is turning out! it looks adorable. Maybe he can have a name like Bruey?
Great job!
Nice. Yes, like the Silent Running Robots.
Amazing content!
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.
Yes! Please see it through to the full design with the head!!!
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!
Very awesome!
Brilliant.
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!
"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.
Amazing
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)
Awesome.
Your prototype immediately has me imagining a little toolbox buddy to follow you around the shop. Someday!
It’s definately on its edges…. that’s it! Make an ice skating robot next :-) Fun project for the holiday seasons coming up.
Very cool so far. Would be nice to see it taking a much longer step forward on the up stroke and a longer pull backwards on the down stroke. I also wonder if a sudden flick forwards of the foot would be enough to pivot on the other foot, giving a basic rotation control?
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!
Yes, James, it does remind me of Huey, Dewey and Louie.
Amazing build! Now for the next big project; building Vasco from Starfield!
Hey James, firstly, great video (as per lol). Secondly, I have been going crazy trying to work on small bipedal robots using microservos (cheap sg90’s), but I’m constantly running into jittering.
I’ve seen suggestions online, but do you have any best known methods to working around this issue? I feel like I’m missing something obvious.
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"!!!
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!
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...
"Whoops!" 😄 Great job managing expectations, there.
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".
Coefficient of Wobblyness is a turn of phrase I didnt know I needed until now.
This is amazing, and if you make a second one you already have the lion's share of an ED209 for the RoboCop fans.
He just a man in CZcams ❤
I'd love to see more about the source code and its explanation! XD
Awesome
That is awesome, and its the kind of thing I subscribed for. anyway using the IMU couldn't you measure the speed at which it is tipping and use that value to control the timing of the feet?
Awsome video.
Suggestion: attack/delay/decay trimming for gait, as a simple framework to control the aggression of foot down/up
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.
Wow you figured out it's movement exactly.
Please put on the eyes you made for the Arduino tutorial. It would be hilarious to see that!
Well done....
Oh dude, Silent Running reference ftw- that'll be your next project :D
GREAT
I was also thinking it looked like the robots from Silent Running. All you need is a little watering can. Great project.
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.
