Justinratliff's EZ-Elf Robot
EZ-Elf Christmas robot built from EZ-Robot parts, a playful holiday project evolved over time.

Are you thinking of building something like this? This would explain your Inverse Kinematics interest.
I have seen some packages of the new "drum-shaped" actuators (4" diameter I think) for building these dog and cheetah like bots. Seems like $600 on the low end to $12000 or so for the key hardware. Very interesting but most likely beyond my skills and budget.
Same here, I was just throwing this out in the open, so you guys won't miss out on it...this ai is crazy good!! That new robot you are building is totally what I am aiming for myself, I might get those tracks, and borrow some of the design if you don't mind?
But actually every now and then, the idea of building a little robot dog crosses my mind...I would go for a cheaper and more affordable version though!!
Saw this 2 min paper last week...so amazing...AI teach robots to walk is the new future and the key to plug and play robots.
