- Опубліковано 2 вер 2018
- Part 7 of my openDog open source hardware & software Dog Robot. Now it's finally time for the electronics installation using Arduinos and ODrive Robotics open source brushless motor ESCs. There's quite a lot to this episode in terms of work and wires, as well as a lot of explanation about the setup!
My open source robot dog project. It includes everything from 3D printing to coding, including a lot of CNC cutting and installing all the electronics myself.
If you want your very own four-legged friend to play fetch with and go on long walks then this is the perfect project for you. This way a dog can literally just be for Christmas. The full CAD is available at the link below for anyone that’s keen to build their own.

② XROBOTS
Former toy designer, current UA-cam maker and general robotics, electrical and mechanical engineer, I’m a fan of doing it yourself and innovation by trial and error. My channel is where I share some of my useful and not-so-useful inventions, designs and maker advice. Iron Man is my go-to cosplay, and 3D printing can solve most issues - broken bolts, missing parts, world hunger, you name it.
XRobots is the community around my content where you can get in touch, share tips and advice, and more build FAQs, schematics and designs are also available.

freaking awesome, as expected. the conduit was a nice touch. Each addition to the body (like the rack for electronics) seems really well thought out. great job!
Well it worked out all right in the end!
Umm... I'd prefer a standard black 1 inch split loom to those oversized yellow tubes, to be honest. Everything about the design so far has been form following function, and there's a real aesthetic appeal to that, but the yellow tubing looks kinda contrived. That sort of cosplay-style touch doesn't really suit this open source prototype, in my opinion, and standard split conduit is easy to get hold of. Also, so far everything that's yellow has been 3D printed, which is a brilliant design choice, and having the pipework yellow confuses what's what. My two pence worth. :-)
Maybe it just needs yellow tie wraps :)
The tie wraps aren't 3D printed either. I think it's better to be able to see at a glace which parts are 3D printed.
The amount of work you have done on this in such a short time is amazing. Hats off to you James :)
James, before anything bad happens, please, put some fuses in series with the LiPos. Your not burning house will thank for them!
He still needs to run high current I assume, so even with fuses it wouldn't be much protected.
@@MishoIV No. the battery will catch fire if shorted. It needs a fuse that is INSIDE the battery box before even the on/off switch. I learned the hard way but was lucky. I shorted a battery with a length of #6 cable and lucky for me the cable acted like a fuse and vaporized before the battery caught fire. Fuse size is selected to protect the battery and then after that one fuse protects each branch circuit based on the size of the wire.
But he absolutly needs a battery protection fuse that is physically and electrically close to the battery
@@chrisalbertson5838 Since I wrote my previous comment, I actually started implementing fuses in my projects and realized one thing. If you have fuse rated 40A, it won't blow at 40A. So if you have electronic that is using 10A constant current, but peaks at 70A, it can be fine to use 40A fuse.
What I originally thought that if you have project that has 70A peaks, that you need to use like 80A fuse so it won't go off prematurely. And 80A fuse will protect you less against the short than 40A. That's why I thought it will be still dangerous even when he fuse it.
Also why it needs to be close to battery? Does that make some change? I thought that fuse will work anywhere in the circuit.
@@MishoIV Electrically the fuse can be anyplace in series. But practically one of the failure modes is physical damage to the wire. Lets say your robot rolled down a flight of stairs and there are broken bits of plastic and bent metal. and a power cable is mashed into the metal structure. If there is a fuse between the damage point and the battery it will blow but id the fuse is physically "down stream" it will not blow. Basically the damage took the fuse out of the circuit If the fuse is phyically locate near the battery with (say) a 2 inch long able then there is very littel chance of that short cable getting damaged. THis is a good reason to mount the fuse and battery in the same metal batery box
A machine is only safe if it remains safe AFTER a serious accident. This is what makes safety design so hard. On a car you'd like the gas tank not to explode even after you are rear-ended by a truck.
Also don’t forget a sack of sand for extinguishing the battery fire (or preventing from spreading)
Wow, I never thought I'd see the day! James Bruton doing wire management!! Brings a tear to my old eyes...
This is what I love about this channel and robots in general, they look awesome with conduits and wires and circuit boards exposed whilst functioning at the same time, great job James.
Initially I wasn't too excited by this project but it's really grown on me and may be one of my favorite series yet! I can't wait to see some baby steps!
This series probably didnt get as many clicks as your themed builds. But this is easily the most brilliant thing you have ever shown us. Sturdy, Modular, Simple but robust. And absolutely beautiful to look at.
thanks, well we'll see how it works out!
This project is coming along so well! Can’t believe how quickly you have gotten to this point!
James this is enormously impressive, I look forward to seeing the evolution of this project and whatever you come up with next. Cheers!
This is the greatest thing ever. Cannot wait for the next installment!
This is my most favorite project on UA-cam right now! I subscribed because of it.
Well done James, I am in awe. The time, dedication and knowledge you put in this thing is inspiring :)
The accumulate experience, the evolution of design and engineering is so beautiful to see. I am happy and please to see it. I wish you success and joy on this project and future others.
4 more of these in red,green,black, and blue with the ability to interconnect you can form voltron.

It’s openDog, not openLion.
The attention to colour scheme makes me very happy
This project is really coming along. Thanks for doing this and showing all your steps! It's really fascinating.
Incredible work! Even though everything was designed for functionality, it ended up looking really cool! I can’t wait to see the next update.
This thing actually looks beautiful.. really looking forward to seeing it waddle around
I think you meant to say "leap and bound".
This thing is next level pro James.... AMAZING work !!!
I love how in every episode, not only the physical appareance changes, but the perceptual appareance _drastically_ changes. It's gone from weird shoddy hobby "robot", to sleek and shiny movie-like robot (looks cool but it wouldnt work in real life), to beefy industrial-machine-robot.
I love the bulked-up look of it right now, it looks like it means business
(Please add giant googly eyes to the ends of the leg mounts)
Great idea with the card stack system, really cleans up the electronics and makes it look great.
Oh the many channels I follow this is my favorite to watch. Of those, the robot videos are the best! Keep it up!
It looks awesome with all its electronics and wiring on it!
Looks like a proper robot now!
Very exciting. What a fantastic endeavour. Looking forward to seeing the code and where you’re going to take this next!
This is a seriously incredible project. James you're getting pretty amazing at making robots!
The quality of your 3D prints is astonishing
That is looking amazing now with all the wiring and electronics in place. I cannot wait to see it walking. Watch out Boston Dynamics!
i kinda want to say your not a real engineer. No real engineer finishes a home project without starting 2 others. Your AMAZING!
Unbelievable what you achieved! This project and the design are really impressive! Great job!
Well it's not quite finished yet
Wow, this episode it really all came together, impressive as always James!
omg omg omg, i cant wait for next part!!! what a hell of a great work james!!
You've come a loooooooong way James.......CHEERS
Twenty minutes of smiling! This is such a fantastic project! :D
Great work! It's coming together nicely!
Looking good.. Very impressive build sofar. If very, VERY yellow!
Can't wait to see if you can make it bounce into the air at least once!
Coming along nicely...you've put alot of work in in a short time. Looking forward to it moving.
Holy crap man! You are so incredibly productive!
It's looking very impressive so far! I can't wait to see it running. :-)
I love the reminiscence of boston dynamics' dog style robots
What about a big red emergency stop on the remote as well? May be useful during the robot uprising...
I could have a soft Estop, the one on the robot actually resets the ODrives with the reset pin
Sure. Event organisers (who like risk assessment forms) would probably feel better about public demonstrations if there was a stop button on the remote that anyone with no training could hit at any time...
I'll consider a 'motor enable' switch on the remote when I get there. The red button on the robot is probably better for the person getting squashed though ;-)
Might also think about defaulting to e-stop on lost contact with the controller. Keep it from running away unless an advanced mode/autonomous mode is flipped. Keeps the controller simple to many buttons isn't good for demos and off should be off. Should also help with someone trying to hijack control getting shut out without physically resetting/tampering with it.
this is insanly well designed. incredible! keep it up!
That was impressive dude ! Keep on the great work !
Dam! All I did was build a 3D Printer from scratch. This is freaky awesome!! (and a bit overwhelming...)
Thanks for posting it as open-source. Maybe I'll try it someday
Awesome man, keep up the awesome work!!
James this is just art! Great work!!
thanks!
amazing stuff. looking forward to seeing it get around. cool design btw
Looks good. I highly suggest having the emergency stop button physically disconnect power from the batteries (through a contactor). That way youre not relying on any electronics working properly in an emergency.
You did quite an amazing job! Keep it up
How can a person handle both programming and hardware skills so professionally? I always awe you when I watch your project. You are my role model ! I am studying Electrical and Electronic Eng and love to make a robot like you but I always feel how hard to actualize my idea without any limitation. However, I often got courage and knowledge from you when I watch your making process. I am sure you will be one of the best roboticists in the world and I also want to be an engineer like you. Thank you for your breathtaking skills and idea everyday
Well, I can hack around until it works"
Looks extreemly cool
Cant wait for the next episode!
James, this is amazing, you are a true inspiration!
thanks
James, you should mount Richard 9000 on top of Open Dog! LOL. You could show up Boston Dynamics up with a bizarre neck and head for your dogbot.
++
Great Idea.
If you could get four of them working on the back you would have a robotic displacer beast.
lol, use one for the neck , one as a tail , and an extra one attached to the bottom if you want people to know that it's a boy .
I think the 3-headed dog is called Cerberus 🐶🐶🐶
You and I both know that it shouldn't be attached on top...
It looks really good! very impressive
I'm unsure if youtube is hiding your videos for whatever reason? But this is the first dog robot video of yours I've seen and i'm already blown away! amazing work as always, james :D
Turn on notifications!
Fantastic!! Nice board trays. @@ Looking forward for more.
Others have commented about fuses. It's not a bad idea, usually a power distribution board makes sense. I don't know the current draw of the motors or the rating of those wires but maybe a 10-20 Amp poly-switch resettable fuse per section would do the trick. What's nice is that those just shut down temporarily.
It's also important to remember that the main goal is to protect the wires, so sometimes protection needs to be cascaded with the wire branching or into the end devices.
NICE WORK i love it looks so awsome even tho you have not finished it !!
Really enjoyed watching it. 🙂
I'm, SO, jealous. Fantastic job man :D
man, I really need to start supporting you on patreon again. I was not a big fan of all the robot x cosmetic stuff to be honest but this is absolutely astounding. This is why I am subscribed to your channel, keep up the amazing work!
great, thanks!
First time I say this, but thank you youtube for leading me here! Absolutely thankful!
thanks for watching! More of this coming soon
Awesome work! Love seeing these progress and come together. One suggestion if it hasn't been made already. Put some sort of rubber insulation over the bolts that distribute power to prevent anything from falling into it and bridging the connection and shorting something out.
I love your work...ur crazy stuff keep me motivated....
A lot of work, a lot of great work thank you
lol this thing just gets bigger and better. I love it.
From the thumbnail i first thought it was a lego technic model of the openDog :)
If it accidentally rolls over, it might ruin the electronics... Awesome build and great work! You're amazing James :)
Amazing stuff. You clearly never sleep. But yeah -- FUSES!
Technology is sexy. This may be far beyond me, however everything looks neatly wired, it has a place to go and a purpose for being where it is, and overall the build is well managed and visually pleasing. Well done.
Love your work, keep it up
No fuses on the power wiring ? What could possibly go wrong...
The ODrives are pretty well protected
Probably you are right, but shortage can occur anywhere in the circuit. Imagine to drop a wrench into the power distribution. it will shorten between the bolts. You should consider fuses. Things can get wrong in so many unforeseeable ways - that is the Law :)
You can’t seriously have watched this whole video and had that be your only comment.
Some sort of circuit breaker might be a nice way of doing things; you can get some quite nice units for car audio etc. Would also give a convenient way of quickly killing the power too, as most of them have a red disconnect button. Using the Estop to hold the reset on the Odrives isn't much help if things are going Smokey
@@kaden56 you are right, I am generally amazed from what James do. He is one of my heroes. The things he done so far are exceptional. This particular build is one of his best! I just was on my work place and did not have the op to shera more than my concerns! Sorry about that! :)
This is so awesome !! Keep going :)
Don't bother with the ITX board and go with a NUC instead. 4"x4" full blown computer. It would fit on one of your hang cards.
This is beautyful!
You are absolutely brilliant
congratulations, very good job.
Incredible!
good lord from the thumbnail i was sure that was LEGO.
Well done, brother.
this is looking good~
Incredible progress! Saw you briefly at EMF, btw.
Awesomeness!!!
Hate waiting for these vids! XD
Love it!
This is awesome, I shall try to make a miniature one 😁
The home switch James u forget that REMINDER!
You really can't help but think of LEGO Technic with all those PLA yellow parts, can't wait to see it in action! Who knows Jim Maybe one day the designs you've made will one day help in a recovery effort from a natural disaster, they're really quite good
He will be working in zero dawn project. xD
This project is awesome. Keep going.
Regards
Sir. You are amazing!
Damn that thumbnail was badass!!
I can see it being fine with walking, and more than robust enough for a heavy load out with this particular drive system (screw drives being inherently self-locking), however it seems like there's a lot of spool-up or spool-down inertia to overcome in order to get some fast movement for running or jumping. So it'll be interesting to see it in action.
Might have to consider a linear motor setup or compressed air piston actuators for a fast version, but trade-off having less ability to carry heavy stuff or hold position when unpowered.
It looks very industrial with the yellow. :D I like it.
James should try to get Catepillar Tractor as a sponsor
Bro that’s awesome
Like very much all parts specially your skill and ingenuity
thanks!
I would like to know about your controller in videos
17:25 lovely wobble on your spindle there.
nice work
AMAZING!
This is so cool, I'm going to build my first robot. I've got the laser cut parts just arrived in the post (I'm not designing my own)
Love the videos!! You are incredibly Smart Man!! Keep up the wonderful work!
So... fridging... sick!
Its almos ready YAYYY
