This gihub link may be a better one, as it provides demos, hardware, software, and design descriptions along with the schematics, pictures, and ICRA paper reference: https://github.com/Nate711/StanfordDoggoProject

But is a different project for a bigger and more expensive design.

Here is a GitHub link to the actual Pupper project: https://github.com/stanfordroboticsclub/StanfordQuadruped and not to Stanford Doggo.

For about the same price, you can build a "spot micro" [1] if you have a 3D printer. I haven't build one myself (yet) but it's been fun following them. I came across them when someone in HN posted how to train it using OpenGym (will find the link when I'm not on mobile). [1] https://gitlab.com/custom_robots/spotmicroai

Do you happen to have a video of the spot micro actually walking? I can’t seem to find any.

It is easy to make a spot shaped object. Making it walk is the hard part.

Watching this is really heartwarming. It's inspiring to see young talented minds directed towards curiosity and engineering while also sharing the fruits of their labor for everyone else to benefit. Kudos to the team!

This is the link to the OpenGym I mentioned before. There's a couple video on their slack/discord(?) channel. I have to dig for it though.

should not be 600 those servos are pricey

I summed the BOM table it was just over $330 but it looks like that's just body no electronics at all... the servo arms look special/priciest but it's multiplied. I imagine the main thing for this aside from body is the brain but that looks to be shared as well

I want this but where it's self-piloting/long lasting(battery) and can build a point-cloud of my apartment as it navigates. Also one for outdoors just wanders in a farm or something... I don't know has no purpose but "neat". Maybe you program it to do a routine where it walks around takes photos of things throughout the day, self charges.

edit: to clarify this isn't a negative comment/criticism. I'm saying I fantasize about having a platform like this but with the capabilities I mentioned(which I'm aware is not easy).

Currently I can't even program/make that gait that makes it move so smoothly so I'm definitely not criticizing.

Earlier quoted context omitted.

> the "Nano Dog" is probably a cheaper and more approachable option for the garage engineer. Hard to find out much about that or OpenDog in general. I've found videos and 3d printer files but nothing that I can read to understand what it can do and why I might want to build it. Or do I really have to watch a bunch of YouTube videos? I hate video. Have I missed the actual project page somehow?

https://github.com/XRobots/miniDogV2 The code's a bit of a mess -- James is clearly not a software engineer first. This is totally understandable, given that he does so many other things! When I first saw the code, I thought about doing a refactoring pass and making a pull request. It would be painful to test correctness without the hardware, and I don't want to make things worse, so I haven't.

Oh wow, you're not joking. I'm getting flashbacks to when I supported a team of EEs.
