Walking Mechanism Using a Klann Linkage

The picture above show the original model, and another has other four leg to make it more like a real spider. The Klann linkage is a planar mechanism designed to simulate the gait of legged animal and function as a wheel replacement.

Point F is their intersection. Here we use those tables, but with the point description oinkage next to it. Translate point H mapping point G to point J to obtain point K. It was developed by Joe Klann in as an expansion of Burmester curves which are used to develop four-bar double-rocker linkages such as harbor crane booms.

Also reflect plane P in this plane to obtain plane P’. Point E is the intersection of the two circles. By using this site, you agree to the Terms of Use and Privacy Policy. Draw a regular octagon around z-axis through point A. In other projects Wikimedia Commons Wikibooks. On Wikipedia, there is a need to compromise between readability, details and amount of illustration.


Point G and H are adjacent vertices in the regular octagon, and point I is their midpoint. Click right pictures to see the animation.

Klann linkage

From Wikibooks, open books for an open world. From Wikipedia, the free encyclopedia. Wikipedia has related information at Klann linkage. As the author of lonkage book, I would like to cite larger sections of the patents.

Hide previous three circles and line. Draw a new regular octagon around this line through point B. By “connecting the dots” without suffix, “x” suffix and “y” suffix, we can derive a first meaning from the drawing, showing us the frame and the leg in two positions. The proportions of each of the links in the mechanism are defined to optimize the linearity of the foot for one-half of the rotation of the crank. Unsourced material may be challenged and removed.

Take a movable point M on the circle.

In other projects Wikimedia Commons Wikipedia. Connect segment BE and EF.

A big thanks has ilnkage go to the patent holder Joseph Klann for his website, [1] which is a great reference and for uploading pictures [2] to Wikimedia Commons. The design of the Klann mechanism is portable with less linkage for linkagw. It can step over curbs, climb stairs, or travel into areas that are currently not accessible with wheels but does not require microprocessor control or multitudes of actuator mechanisms.


Point D is their intersection. Archived from the original on 14 April Draw a circle in yz-plane centered on point O of radius 0. The linkage consists of the frame, a crank, two grounded rockers, and two couplers all connected by pivot joints. The robot comes to an almost stand still during each crank revolution. The input variables for figure 17 and therefore table 1 according U. Create a plane bisecting the remaining regular octagon.

Llnkage linkage work on the basis of kinematics where all links gives relative motion with each other. The Klann mechanism uses six links per leg, whereas the Jansen’s linkage developed by Theo Jansen uses eight links per leg, with one degree of freedom.

The following is a detailed construction process. Hide point G, point H, lineand bigger regular octagon.
