The Jansen's linkage is a leg mechanism designed by the kinetic sculptor Theo Jansen to simulate a smooth walking motion[1] Jansen has used his mechanism in a variety of kinetic sculptures which are known as Strandbeests. Jansen's linkage bears artistic as well as mechanical merit for its simulation of organic walking motion using a simple rotary input.[2]

While legged walking mechanisms have been designed and built based on engineering theories, they have also attracted much attention from the art fields. The kinetic sculpture “Wind Beast” is a multi-legged walking mechanism powered by wind. It was created by Mr. Theo Jansen, a Dutch kinetic sculptor. The mechanism has many advantages from the design viewpoint, such as: it has a SDOF, a crank as an input link and an ovoid foot path. Also, two legs are in pair and are mirrored, where they share the same crank as the input link. This is beneficial because a central shaft can be used to operate all the legs without adding extra actuators.
