Conceptual Design of a Single DOF Human-Like Eight-Bar Leg Mechanism

Legs are the most important elements for accomplishing human physical work including transportation or displacement. the article presents a mechanical reproduction of the human walking apparatus. using design rules, a final mechanism configuration is achieved such that the crank is a binary link connected to a binary ground link. the resulting linkage is a single degree-of-freedom (dof) eight-bar mechanism. the mechanism exemplifies the shape and movement of a human leg. the mechanism is simulated and tested to verify the proposed synthesis.
