Got to say I love your style of videos, they're not over the top, dramatic or sugar coated. Instead they're a really good and fun to watch build and project log with you sharing not only what you've done but how, why and where things go wrong, right and future tweaks or ideas. Really appreciate your videos.

Really?! Damn! Designing in CAD, 3D printing (which always need constant adjustments, filament replacement, upgrades and staying on top of the newest in tech and theory), making and editing videos, keeping up with the latest automata tech and computer programming, testing, coming up with more ideas, eat, sleep and do this every week! You are a machine!
Great project but you really should have some fuse protection in your power distribution, as one short or a failed odrive could cause a major burn-up with the current available from that battery. I'd suggest something like an automotive blade fusebox, with a separate fuse to each motor, or pair of motors.
I want to thank you for this series, i am working on a robot warm that is open source and can be made realtifly easily and uses wood construction to reduce the plastic impact of the project. I have hitten a brick wall but thanks to your video i gotten quite some nice ideas to continue the work.
like a single battery, only a single concentrated power motor, also a single position encoder, then be sure of the variable transmissions, and/or just imu per joint
A handful of ideas for you: Print a module with a mechanism that retracts the D-Sub connector to allow removal of the main controller module without having to remove another cover to remove the D-sub connector manually. You could even implement some kind of cam/tumbler lock to require a key to move the mechanism to prevent tampering. Having a removal mechanism also makes it faster to install and replace the main module with an alternative such as maybe one that is Pi/ROS powered.
Now that I think of it, electrons are basically hydraulic fluid. And batteries are pumps. Meanwhile encoders and circuits are... valves?... Whatever, I just think it's insanely cool analogy between electric and hydraulic robot dogs.
@2:45 how wickedly fast that thing can move when it sees an opportunity to get even... You should treat your hardware better (no torture tests) than maybe you wouldn't have to worry about bad karma!
I've been watching for years now and James must be 3D printing constantly. He really needs a laser cutter. I can't imagine what his productivity would like like if a 10 hour print goes to a 30 minute laser cut. It changed my whole prototyping game.
If by weird "some weird issues" you mean getting absolutely clocked in the face by your own robot, then yeah v2 had some weird issues, lol. Love your channel and your work is amazing, keep at it man
As has been mentioned I'm constantly impressed with your dedication to this project, thank you for making it so all I have to do is print one of these with special hinges and telescoping limbs so it has a backpack mode and I've got a portable printed personal exoskeleton
Awesome work! Has anyone managed to reduce the backlash in these reducers? I noticed quiet a bit when just printing the stls, but think you can tune the tolerances of the discs (inner holes are
One way to do it is tediously adjusting horizontal expansion and outer Wall inset. Print the outer wall first. Between these settings you can close the tolerances to the limits of your printers motion system. On my printers I've gotten as low as .04mm average tolerances. It's a pain to do, but once it's going correctly you'll be getting almost exactly the dimensions you're trying to print. So you can change the hole size via the horizontal layer expansion. Than scale the gear very sightly to close the outer tolerances.
I love your craftmanship-engineering, really nice design, great work. One thing i want to see is a head peace for the dog, it would be better for it's publicity.
Gotta say it's amazing you get results this good out of those taz5 printers. We have 4 lulzbot at my schools lab. They are not my favorite printers. Impressive project, keep up the good work!
I would really consider having that e-stop Open a contactor that kills power to the entire system. An e stop doesn't work for very well if the thing you're asking to stop by pushing it is the thing that's misbehaving to begin with.
its great to see it all together.... i LOVE that spring in its step.. maybe it will have a bit of bounce when it walks and it'll look like its happy lol :)
steel power studs are fine, but might i suggest at least copper or brass nuts and washers for the intermediary hardware between the power in and power out to reduce resistance for less waste heat (in the studs) and better battery life. all copper hardware would be best of course but just replacing only the hardware that holds down the main wires on the bottom will still be beneficial.
Just an idea - you might consider running just one set of power leads from the battery terminal to the just one of the 3 the ODrives in a bank then daisy chain the power lead to the other two.
While I am a fan of generation design there's probably a lot of optimization potential before taking that step. I'll bet you could cut the mass to 2/3rds quite easily with a few tweaks.
For future Opendog iterations, rather than requiring backdrivability, would it be practical to use a higher gear ratio but with some kind of spring/compliance in the legs - this + creative use of IMU(s) would permit some kind of "virtual backdrivability"
This is amazing, you are Rapidly closing in on a truly disruptive open source robot platform. At this point the major weakness is electronics and wiring and that's a HUGE achievement and a fairly trivial problem at the social level. Just need some product niches filled, and even in this video with that pro unit it would appear that's going to greatly improve soon also. After you finish open dog maybe you could work on a 3d printed exoskeleton good enough to replace a wheelchair or a strength enhancer for physical therapy. IMO the most versatile form of robot other than a flying drone would be a wearable exoskeleton that doubles as a humanoid robot. Exciting stuff.
+1 for more IK maths next time. The previous ones were good but I'm still not quite there with it (although probably need to do a rewatch). Mega in awe at the sheer complexity of the wiring on this one! Not sure how you are keeping track of it all!
hi i've seen taht for a possible leg, i don't know how backlash would factor in but i think it could be programed to be quite springy, but know idea about the complexity of realisation. sorry for the poor writting. And thank a for your work and also the "open" part, really cool!!

I feel so bad for saying this, but I nearly spit out my drink in laughter when it clocked you in the face
You can't say that the legs aren't fast enough. 2:54
Spoiler alert.
"Sometimes there were still some weird issues"...
oof.
When the robot dogs want retribution for Boston Dynamics...
What did the 3-d printed ball-leg say to the face? SLAP
James: "... some weird issues"
OpenDog V2: "And I took that personally!" *SMACK*

I like this dog as it uses passive dynamics in its walking.
Looks more natural than the boston dynamics in that yellow one.

It went into kill all humans mode. Jonny 5 alive
Seems more like the actions of a cat than a dog lol
That thang socked em
Behaves like a Robo Horse
Odriverobotics, send this man some upgrades for the next robot dog, pls!
itd be cool but also as the more expensive the hardware gets, the less people will be able to recreate it
@@bbenny9033 True, but the other dogs are still there, if people want to get started.

2:55 robot uprising has begun :) anyway, beautiful engineering as always James, well done and very nobel of you for making it opensource
open dog v2 always reminds me of a bulldog and is quite cute in its movements, i can't wait to see how v3 turns out as it looks so promising so far!
V3 looks like more robot and less leg from the side, due to how tall the frame is, I think it looks good
2:54 did that robot dog just abuse its owner? That's too funny.
It's making up for all the testing at Boston Dynamics...

I'd suggest something like an automotive blade fusebox, with a separate fuse to each motor, or pair of motors.
That is true, probably one fuse per motor. It could be 60A though.
@@jamesbruton 8-10 bucks (USD) per fuse seems a lot cheaper than the motors/controllers :D
oh my god i didnt even realise that nothing here if fused!! man i stick fuses EVERYWHERE in my projects

2:54 the time where he got punched right in the forehead by his creation 🤣
This made me chuckle 😆
I love how you 3d printed a work stand for this project.
One of the best projects on RUclips.
Looking better and better!
the red and white look great, amazing work, both in quality and quantity 🤍
Well that a nice slap 2:55
Amazing progress James, I hope you are ok after being hit in face by that naughty dog.
Nice. James you have built everything but your own motor....

2:54 - SkyNET activated lol
That looked painful though, glad to see you can laugh about it now xD
The Odrive pro reference @7:30 ; should be on every mechatronic hobbyists' wishlist.
I've been watching for years now and James must be 3D printing constantly. He really needs a laser cutter. I can't imagine what his productivity would like like if a 10 hour print goes to a 30 minute laser cut. It changed my whole prototyping game.
Prints can be made overnight and when he prints daytime, he can do other stuff in parallel. It is all about planning the workflow.
Ooh dear, those unprotected screws for distributing the voltage made me nervous having shorted those kinds of batteries before....
2:54 Children are like that sometimes.
2:54 LOL
I think he was sleepy and didn't wanna wake up xD
This is looking really excellent James!
this is a beautiful build. i’ve seen “professionally done” electronics in much worse shape with cabling and connectors not as well thought out. kudos!

Wow opendog v2 kicks hard
What about mounting the legs at 80 degrees instead of 90?
Should help with side wobble.
Your printers look so solid 👌
Leg locking blocks for servicing a live machine would be a good idea. could be very dangerous lol
Congrats on the million+ subs!
2:53 dud gets railed hard and took it like a OG
solid. better. good evolution.
So intriguing. I was really not expecting when you were calibrating v2, and it punched you in the face. Yikes! Great work on your innovations!
MAN! That is awesome!
For future Opendog iterations, rather than requiring backdrivability, would it be practical to use a higher gear ratio but with some kind of spring/compliance in the legs - this + creative use of IMU(s) would permit some kind of "virtual backdrivability"
he tried that in v1 but it is a lot easier to do it that way
I can’t Imagine how much money just those 6 odrive motor controllers cost. That’s over $1000! Not even counting the motors!
Robots are expensive... makes me sad...
Dude took that blow to the face like a champ!
I like how the yellow robo doggie legit was like don’t touch me n punched you for a second I thought some ai was showing

the design of the endplate is calling out for googly eyes to cover over where the bearings sit :P
OMG! i believe spot from boston ! is 65K wonders what you could do with the cost of one !!!!! keep on have fun !!!
