3D Printed Walking Robot (Klann Linkage): This walking robot has been a project that I have been wanting to have a go at for a while now and I finally got. PDF | On Dec 1, , Jaichandar Kulandaidaasan Sheba and others published Design and evaluation of reconfigurable Klann mechanism. PDF | In this paper, discuss the spider mechanism (Klan’s mechanism) for any random movements, whenever the transformation by wheel is not possible.

Walking Mechanism Using a Klann Linkage
The Klann linkage provides many of the benefits of more advanced walking vehicles without some of their limitations. In yz-plane, draw circle centered on D of radius 0. From Wikipedia, the free encyclopedia.
It is a bit tricky to realize in the animation, but obvious in the graph: Show previous hidden three leg. Wikimedia Commons has media related to Klann linkages.
This page was last edited on 24 Januaryat Draw a circle in yz-plane centered on point O of radius 0. Translate point M mapping point Linkgae to.
Hide the useless objects. Connect segment BE and EF. In other projects Wikimedia Commons Wikipedia. In other projects Wikimedia Commons Wikibooks. Hide the bisecting plane. In the patent, there is are two tables with coordinates. Views Read Edit View history.
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. A big thanks has to go to the patent holder Joseph Klann for his website,  which is a great reference and for uploading pictures  to Wikimedia Commons.
Klann linkage – Wikipedia
Archived from the original on 14 April Point E is the intersection of the two circles. Click right pictures to see the animation. In other languages Add links. For convenience, we leave the first leg, and hide three other legs temporarily.

Presuming that limkage fasted foot defines the speed of the whole robot, we can animate a Robot based on the values in table Point G and H are adjacent vertices in the regular octagon, and point I is their midpoint. The number of links in the Jansen mechanism is greater than in the Klann mechanism, and is more costly. There is not construction process of first picture since it is contained in the second one.
Hide previous three circles and line. Mobile robots and uncrewed vehicles. The proportions of each of the links in the mechanism are defined to optimize the linearity of the foot kinkage one-half of the rotation of the crank. As the content of a patent may be copyrighted, this book will only cite small sections of the patent to be on the safe side.
Friction is required for motion between the legs and surface so it can hold, otherwise it will slip.
Hide point G, point H, lineand bigger regular octagon. Two of these linkages coupled together at the crank and one-half cycle out of phase with each other will allow the frame of a vehicle to travel parallel to the ground.
This book will shall not replace klajn the patent, but simplifying it by providing additional tables and illustrations. November Learn how and when linkgae remove this template message. Take a movable point M on the circle. Reflect two triangles and two circles to obtain two new triangles and circles. From Wikibooks, open books for an open world.
Retrieved from ” https: Draw a sphere centered on point N through point B. Rotate previous regular klqnn around this line mapping point G to point I to obtain another regular octagon.
Draw a new regular octagon around this line through point B.
Retrieved 22 November It is impossible, to give an overview to the general public and an in depth view for engineers diving deeper into the topic at the same time. Create another bisecting plane of regular octagon.
The following is a detailed construction process. Without the pictures from Joseph Klann on Commons and without his website, klqnn book would not have been possible.
