We already know the Klann linkage, Theo Jansen / Strandbeest linkage, Chebyshev Lambda / Plantigrade, Ghassaei, Strider, Trotbot, and many more, which are all designs for walking mechanisms using single rotating crank and several bars connected with hinges. I tried yet another mechanism, using the common 4 bar linkage but with the foot link shaped such that the contact point is not constant. While the movement is advancing, different parts of the foot will touch the ground, like the heels and toes of human foot.
