I'm looking to find out, How do human-like legs compare to chicken legs and four-leg systems?
I'm interested in things like speed, agility, turning radius, complexity and cost.
For a design large enough for a person to ride, rider fatigue is also important -- how do they compare in terms of achievable ride smoothness, vibration, and so on?
Are there quantitative benefits of 3 DOF hip joints, compared to 2 DOF?
I realize other factors will come into play as well, such as actuators, joint designs and control systems. However, my interest at the moment is how basic leg designs compare to one another.

How much detail are you looking to go into? Is it for a school project? The walking gait will play a huge issue, as well as the actuators you use to replicate motion. Robot’s still don’t have anything to really replicate muscles etc., so the efficiencies between a robotic system and an organic one may be completely different. The theoretical motion between a a chicken leg and a human leg are the same (the motion is just reversed). Start with a torque balance (static and dynamic) and then proceed with different gaits.
Not necessarily human like but close
I’m trying to make a model human robot with 26 degrees of freedom. But I’m not neccessairly trying to make it utility. I’m trying to make it fast. I want it to sprint. So I was hoping to find an engineer I could talk to or hire who can help with some fairly analytical questions. Do you know anybody like that?
This is where I go for ideas.
This is the best place I found for leg ideas.
