Robot Dog V3 - 3D Printed & Open Source #1

[@derjansan9564]

Just last night I was thinking "Too bad James Bruton doesn't work on his dogs anymore" and here we go! What a great way to start a day.

[@djTokie]

With all these printed parts, the whole thing also takes a little time :D

[@CYDeviant]

Are you kidding me? The man never sleeps. He's literally Jimmy Neutron all grown up.

[@itsprobablykiaan]

Dude that was me this morning! This series, Jerryrigeverything's hummer and Colin furze's tunnel (idk where colin is) they're all giving me life right now. Thank you so much James, Jerry and Colin!!!!

[@professorpikaeeveerockruff6868]

But a fool you were

[@jeroen94704]

It’s almost sacrilegious to reduce this amount of development work down to a 14 minute KZbin video! I can only guess how much time this took in real life, but it must have been very substantial. Anyway, this looks really promising, and I can’t wait to see the end result.

[@aurigo_tech]

And he is doing this every week.

[@williamrutherford553]

I'm sure that the development from v1 to v2 to v3 impacts that greatly. Very little of this is things that he hasn't done before, this is more a perfection of version 2 with the gearboxes.

[@JarydGiesen]

Mmmmm yes, been waiting for V3 keenly. New colour scheme is mad as well

[@felice0miserable218]

Ikr

[@irltankman]

You can see all the lessons learned from v1 and v2 in v3. The pace of build is also so much faster. It looks lean and refined. Excited to see how it performs with electronics onboard!

[@ww-pw6di]

There is going to be v3.1 though. There's no way that he won't fix the top bars :)

[@MaxMakerChannel]

Its amazing how much you can done in such a small time. So many projects, so much CAD work and then the editing on top of that!

[@rdyer8764]

I'm amazed by how much quality work you do in a week - from design to printing to assembly to video filming and editing. Do you have people who help you get all this done?

[@thyros_]

what happed here

[@rdyer8764]

@@thyros_ No idea. I've reported some of them, but more came.

[@Avetho]

@@rdyer8764 There's multiple bots and Google won't do anything to them since they're small time, they have more important things to do like banning free speech and all that :P Edit: I'll just say I spent around 10 minutes combing through the comments section and reporting all of the Rita-Bots for spam (over a hundred methinks), it gets a bit faster once you streamline the process and get more efficient at it: (triple dots, report, unwanted commercial content and spam, ok, ok, scroll to next bot)

it's crazy that James puts all this work into making these fantastic projects, and then just... makes them open source. Honestly a huge breath of fresh air.

[@cem_kaya]

​@@ericlotze7724 cant wait to see that pack.

[@owiela]

Every time you see the prints, you realise the amount of time he's been working on his projects. That looks like weeks worth of printing, at least!

[@GALENGODIS]

Fortunate he got loads of 3d printers :D

[@rorygallagher628]

Oh for fecks sake Rita go home, no one wants to hear your poetry

[@Avetho]

@@rorygallagher628 Its a bot not a person, best to just report it and move on, especially since there are more than two of them iirc Edit: Frankly, its somewhat amusing and infuriating in equal measure just how little Google actually cares about spam bots and other things like that since they don't do anything but ban people who say things they don't like

[@MikePorterII]

Thanks!

[@StevenIngram]

The build so far is looking like a well integrated piece of kit. Looking forward to seeing its evolution.

[@cozicjean-sebastien8082]

Damn, the more I look at this channel, the more I want to start building bots... So cool you are making those kind of OpenSource project , really helpful for begginer, will totally try this out!

[@Bigbossperson]

These videos are such insanely high quality. Congrats on 1M btw!

[@braspatta]

Ivan Miranda definitely approves the colour of the dog!

[@masonl87]

I know about 15% maximum what's happening here, but I do know that this is some engineering-ass engineering!

[@alex4alexn]

You are a mad genius. Any other you-tuber would make this build a 30 part vid series just to get as far as you did in 1 vid....super exited for he next episode!!

[@milindsharma8106]

This is crazy awesome! As an engineering undergrad, the more I learn the more I appreciate how hard every part of the process of designing and building such a robot is, and you just nail every part of it!! Now make it fetch 😉

[@TheAstronomyDude]

Red and black looks so nice.

[@kschleic9053]

It says something about the quality of your videos and the caliber of your audience metrics that a high end professional engineering software company like Altium sponsors you!

[@RadekMacha]

James is an actual modern-day hero of the people. Big up, my man. Love to see the dogs project getting some more love.

[@FreeRiderx388]

Hvala.

[@U.P_SCUBA]

So lucky to have some one of this skill just sharing videos and ideas to the internet. Thanks for always keeping my mind active.

[@stocchinet]

Finally, when the wacky wheel saga ended our robot good boi has returned

[@wkool9430]

It's a cycle, he builds a dog, goes onto do seemingly random things, then comes back to the dog with what he's learned, repeat.

[@theofficialczex1708]

I really appreciate you taking the time to develop this and share your knowledge with us.

[@richards7909]

“Open Dog version 2 which works ok.” I think you’re underselling your achievement there James!

[@TheMeditron]

The work you have been doing has really paid off, that thing looks stellar! Excited to see how it runs!

[@DamianReloaded]

Wow man I'm out of words. I love how you iterated the motor design and now your assembling v2. Too good!

[@TheTsunamijuan]

If weight wise the bearings are still to heavy, consider trying UHMW rod. UHMW has a great natural lubricity to it. As long as your not putting UHMW against itself it slides wonderfully. Which would be a considerable weight savings. I would say that nylon didn't work as well partly due to the fact you had one solid rod interfacing with both the upper and lower drive, which are moving opposite each other.

[@joe7272]

If you use UHMW naturally it would be possible to replace those labor intensive metal rods with larger, printed fitting alternatives right?

[@TheTsunamijuan]

@@joe7272 i am not sure tbh, i have only used it in small applications for its lubricity. where the material thickness is thinner to begin with. In these applications till will compress and deform. But that is not considered a problem. as it returns to original shape unless marred by something. I now i tend to favor metals for shafts as opposed to printed ones, partly due to the lack of layer line weaknesses and dimensional stability.

[@lightdark00]

I think your greatest joy is to keep coning up with new iterations of robot dog. I think you'll be done when it can do all horse movements and jumps.

[@TheRinger1976]

This is the bread and butter... the very reason I watch this fantastic channel... the open source boston dynamics-ish nightmare... I want to be able to print my own version of what keeps people up at night...

[@colinmj.jalbert5436]

Hell ya James, I appreciate you carrying the torch for 3d printable robotics for humanity!!!

[@fatgamer919fan4]

So much printing, screwing and cutting, this is determination

[@MatchaMakesThings]

Well that came out of nowhere!!! Cant wait for Open Dog V3.

[@_ShaDynasty]

This guy is brilliant, the amount of work to do this alone is insane .

[@DoomLatveria]

You are an inspiration sir. 2 months after this video is posted, I'm sitting here debating on if I shouldn't give up on a dream for robotics, but no. Driven on again.

[@jannic7506]

I see it: Bruton Dynamics :-D. DIV-Dogs for everyone Well done. Exited what you will develop in future

[@garyseaman6105]

The movement of robo-dog does have an excited character to it. Thank you for an excellent video.

[@WetDoggo]

To debur the rods you can make a jig with either just a hole or a few bearings🔥👍 Hold the dremel in the right angle and enjoy the satisfaction before you run out of rods 😁

[@Drawliphant]

It still breaks my brain that these are so back drivable. Awesome work. So much progress in so little time

[@darke7777]

Looks great. The problem with leg hitting carbon fiber tube: maybe you don't need two tubes at the top, and could change to a single top tube in the center?

[@Robotron-zg6mf]

cool idea! like a back bone

[@ArtamisBot]

Every time he makes a new robot I am impressed at how much the quality is improving.

[@jaysonbunnell8097]

It actually weighs as much as a real dog! That's so fun.

[@Innomen]

Speechless. True service to humanity here. Unequivocal praise from me. Thank you and keep going.

[@GuiMVII]

You are a legend. So much effort and quality on such a compact video! Amazing! We need more youtube channels with such high level of content.

[@baseballjustin5]

Just looking at this feels insane. For some like me, there's no way I'd be able to do stuff like this. More Power to ya.

[@nishantsharma4465]

lot of hard work ! It's looking dam cool

[@eski5195]

For the up movement of the leg being restricted, you can redesign the top of the robot to only have one carbon bar on top in the middle instead of two. It should still be stiff enoug for it and will allows much larger movements in the should joints !

[@ronnetgrazer362]

Thought the same thing, and it would shave off a few grams and pounds from the budget, the only downside I see is that stable payload mounting might be a little harder to do.

[@Matty.Hill_87]

This version of open dog is looking amazing already

[@alexandre-e]

Thank you for the great video once again ! I know you composed the previous one, but to be honest, I really like that you changed the timelapse's music. It is much more pleasant on my ears ! Good luck for all the hard work !

[@Crisisdarkness]

Wow, congratulations on reaching 1 million subscribers, I have always admired you, you are a very talented person, also grateful for your generosity, your designs are impressive

[@darktherapy]

Hi James. I’ve been watching your videos over the past few weeks as a “non subscriber” and I’m always amazed at how much effort you put into your projects. This one makes me wonder how you even have time to eat/sleep with all the R&D you’re doing. Finally pressed the subscribe button. Keep up the great work.

[@FrostCraftedMC]

just seeing it on the stand is exciting! i cant wait to see it powered up! the more you develop this the more it looks like spot, its so impressive that youve made this on your own

[@11WicToR11]

I was so sad that you didnt show it working yet ....then i realized you built all of it in 13 minute video. Insane productivity

[@jeffstation70]

Very cool indeed. All those iterations and test builds have definitely paid off.

[@Will_Huff]

Super excited to see this version operate!

[@LoyvanBeek]

Would using iglidur (no, has nothing to do with Tolkien or LotR) bushings from Igus instead of metal or nylon bearing work? Stuff is super smooth and very lightweight.

[@Diggnuts]

The extreme lack of first principle design ensures V3 will have a whole new collection of failure modes and V4 is practically a guarantee. In fact, this is the same prediction I made with V1, V2 and just about every robot project on this channel. Nothing ever gets finished.

[@dujezarkovic2384]

That's the thing with just about any and all hobbyist electronics projects. Nothing ever gets finished. The problem is that the sky is the limit when designing stuff like this. You're not making a product to be sold, so there is no point where you have to say "good enough". You can keep modding it and improving it, and although the process is really fun, at the end of the day you're left with expensive, complicated, unfinished toys. It's the reason I stopped playing around with Arduinos and Raspberry Pi.

[@Diggnuts]

@@dujezarkovic2384 I build stuff with RPis and several types of microcontroller boards for a living. Those are perfectly fine components for projects that are actually feasible.

[@krcb197]

This seems a bit harsh, it depends on the goals and the definition of “finishing”. The goals of this channel are entertainment (which hopefully translates into paying James’s rent, bills etc…). The design and prototyping which make good content here are at best 50% of a “finished” development project, followed by endless testing and refinement which though important is probably less interesting.

[@Diggnuts]

@@krcb197 It sets a bad engineering example. I can guarantee you that this iteration will have new compounding issues do to a lack of addressing earlier compounding issues in earlier iterations.

[@heyitsthatdude17]

So excited for the new iteration James. As a long time viewer, it's been great to see your evolution in design and process.

[@commonfolk663]

Oh yea, I discovered this channel yesterday and just shoved my nose into dog v2, and yay, I'm blessed this video

[@tafaragadze6432]

This level of development by a single person in such a short period of time without millions in funding is unheard of in robotics. Almost sacrilegious. This is truely disruptive. How has general dynamics not hired this guy yet?

[@NHGeneral]

3d printer is the most valuable friend for inventors.

[@BryanBBryan]

I would imagine that there's a lot of friction in between the internal large gears in the cycloidal drive. Have you thought about using large teflon washers or spacers to put in between them to reduce the friction of opposing plastic rubbing against eachother?

[@joe7272]

like another commenter mentioned, UHMW plastic has natural resistance to friction. If it was able to be printed the horizontal surfaces would become irrelevant

[@HeyItsJonSchwartz]

You have a lot of "Draw the rest of the owl" on your channel where you obv hand wave a lot of work on your end. I'm guessing most people don't find it all that interesting, but I'd personally rather see the effort you did to build the things than watching the 3D printer print out a thing. It was nice to see a bit of that effort you put in in this vid.

[@frollard]

my hunch is just that all the detail went into v1 and v2, so it's repeated effort to show it being assembled again...instead just touching on what changed this time.
