One of the first things I tried to do with the Breaking Ground is make a quadrupedal robot in a similar fashion to BostonDynamics SpotMini.
It... works. Barely
This version has a "Stand" and "Walk" function, with work-in-progress "Sprint" function. It's almost uncontrollable without reaction wheels, but that's likely due to poor programming on my part, of which was a pain to do.
The main issue with this style of quadruped that I found is that the servos don't move quick enough to get any decent speed from it, though it does still work.
Here is a video showing it walking: https://youtu.be/QLtOllMOOuU

If anyone can make it work better, I'd love to see it!
