This animation of Jerome Choe’s concept for a spherical archway was generated by Mikhail Zhuk. Spherical rhombus elements form a foldable structure. (UCI Robotics and Automation Lab)

Mikhail Zhuk animated this design concept for an eight-bar linkage to deploy a collapsible emergency structure. A physical prototype is under development. (UCI Robotics and Automation Lab)

The doors of the Koenigsegg CCX open using the “dihedral synchro-helix door actuation” system. You can see this movement on the video:

Joseph Klann provides a useful comparison of the leg designs for his Mondo Spider and Theo Jansen’s Strandbeest at the link:

Here is a walking machine called the Mondo Spider:

The leg of this walking machine 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:
http://en.wikipedia.org/wiki/Klann_Linkage

The leg of the mondo spider has the topology known as a Stephenson six-bar.

Theo Jansen builds amazing walking machines as can be seen in this video:

Each leg is an eight-bar linkage. The Wolfram Demonstration Project models this linkage in a Mathematica notebook. See the link:

This design concept is an 8-bar linkage developed by Minshan Tsai and GimSong Soh for my advanced mechanisms class, UCI Robotics and Automation Lab. It is now on YouTube:

The dishwasher linkage design concept developed by Marshall Meek in my advanced mechanisms course (UCI Robotics and Automation Lab) is now accessible on YouTube:

This 10-bar linkage is designed to drive a scissors movement in order to actuate a deployable structure. It was presented at the 2009 ReMar Conference in London. (UCI Robotics and Automation Lab)
