I'm curious why the leg joints hinge towards the posterior, instead of away from the posterior like they do in dogs. Seems we would want to mimic the nature model as optimal, however does this imply the robot model performs better, in a way that somehow all quadrupeds didn't evolve to?
Or is it some nuance of metals vs carbon-based joints?
Dogs have more joints, one for the knee where the femur meets the tibia and one for the ankle where the tibia meets the tarsal bones. If you just have one single joint in the hind legs you probably want to be able to push off as easily as possible, so the lower one makes more sense.
