Kinetic horse sculpture
This articulated model horse is by the artist James Watt.
A kit for this device and other designs can be found on his web-site: http://clockworkrobot.com/
Deployable archway
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)
Stackable fold-up emergency shelter
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)

Four-bar linkage analysis: 4R quadrilateral
The four-bar linkage is a basic machine component. It comes in two primary forms the 4R quadridlateral and the slider-crank. Here are my notes for the analysis of the 4R quadrilateral.
