Hey all, my group in Stanford Student Robotics made Pupper. Happy to answer any questions!

Awesome project! I'd love to build one, except for sourcing the parts - esp. the carbon fibre (out-of-stock) bits! If your team sold it as a kit I'd be your first customer! Of course, you'd have to ship to Canada too. Q. Was there a price point you had to aim for in the development (i.e. under $1K)? And, if you were to double the price, what improvements would you make (e.g. even better servos)?

We're actually working with some people who are interested in selling the kits as a side project. Stay tuned. With double the BOM cost, we'd use torque-controllable servos. We're testing out the DJI M2006 right now.

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.

For future reference, I saw "OpenDog" and thought we were discussing James Bruton's (XRobots) OpenDog/Mini-Dog, which is where the firmware I linked above comes from.

NanoDog is something different, apparently! Sorry for any confusion I might've caused there.

It's probably also worth mentioning the project is a work in progress, and from the videos, it looks like OpenDog is likely to undergo at least one more major change before "completion".

Has anyone heard of an open source build able bipedal robot? For some reason that’s what I’m really interested in building.

There's blackbird, but not sure of its current status. https://hackaday.io/project/160882-blackbird-bipedal-robot

Wow thanks. Looks neat

Great project, thanks!

Is Pupper in any way related to this quadraped robot here [1] — or do they just have a similar looking physical architecture?

Looks dead. The guy's website [i] expired and his github [ii] hasn't seen activity in 9mos. Too bad, that did look like a very slick project!
