I’ve been wondering lately, why is it that most, if not all, bipeds seem to use a backwards knee setup? Does it have advantages over using a forward knee like that of a human leg?
I’m assuming there is a stability reason or something with the physics of it but I just was curious if there is a specific reason?
Thanks,
well two things at least im sure about
1.stability
2.fashion
i’m just geussing these are the reasons why
but remember im just guessing 
Not sure why you think most bipeds use the chicken leg. There are no real advantages. We made the Biped Scout kit which is a 6DOF chicken leg walker because I was interested in that method. From all of the Robo-One robots I have seen only a few were reverse knee, the vast majority use 5DOF people leg designs.
I though abput the humanoids and remembered that they have a human knee. I’ve just seen alot in movies and such, bipeds (without arms and a “torso”) seem to have backwards legs. I though there was a balancing or stability reasoning at play but apparently I’m just mental.
LOL, thanks for clearing it up.
The project I am working on use also chicken leg walk method but our robot can also walk like a human but in our test the human walk method has less stability.
I think it depends on where you place the servos and at what height you assemble them
But if you build your own biped it must be possible. And i must say the human walk methode looks better.
