## Comparison of Klann and Jansen leg linkages

Joseph Klann provides a useful comparison of the leg designs for his Mondo Spider and Theo Jansen’s Strandbeest at the link: http://www.mechanicalspider.com/comparison.html

This link may be unreliable so here is an interesting article comparing the leg designs:  Mechanical Spider Using Klann Mechanism

This is a youtube video prepared by William Thielicke that illustrates the two leg mechanisms.

## Mondo Spider walking machine

This walking machine known as the Mondo Spider.

The leg of the mondo spider has the topology known as a Stephenson six-bar and is described in US Patent 6,260,862 awarded to Joseph Klann. Access it through the link:

Wikipedia calls this the Klann linkage described here:

## Theo Jansen’s walking machine

Theo Jansen builds amazing walking machines.
Each leg is an eight-bar linkage. The Wolfram Demonstration Project models this linkage in a Mathematica notebook. See the link:

## Linkage for an RV deployable top

This design concept is an 8-bar linkage developed by Minshan Tsai and GimSong Soh for my advanced mechanisms class lifts the top of a recreational vehicle to create a second story, UCI Robotics and Automation Lab. It is on YouTube:

This linkage to lift the lower rack in a dishwasher was developed by Marshall Meek in my advanced mechanisms course (UCI Robotics and Automation Lab) It is accessible on YouTube:

## Materials Selection in Mechanical Design

Michael Ashby presents materials information in a practical format in his book Materials Selection in Mechanical Design.
