Here kitty kitty

It really does look like you’ve gotten the walking algorithm well coded, and the mechanical design looks well done. If you made the gait slower, it might look more realistic. I think overall it looks a bit like a fox too. What’s next in the build? Adding a degree of freedom in the middle? Might want to make the head longer and add a linkage tail. Care to post the mechanics of one leg?

Nice Cheetah.

Very nice work.  I’m still trying to comprehend how the legs work, love to hear/see more detail.
