Animations of linkage movement.

Deployable Arch

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)

Shelter Deployment

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)

Jansen and Klann Legs

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:

RV Linkage

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:

Dishwasher Linkage

Dishwasher linkage

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:

Ten-bar Drive

10-bar drive linkage

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)

Spherical Deployment

Spherical deployable linkage assembly

This assembly of spherical rhombus linkages expands to enclose a volume.  It was designed by Jerome Choe to explore the construction of complex articulated systems. (UCI Robotics and Automation Lab)

Brock Engineering’s mechanism home page

Fred Klingener has generated a number of interesting mechanism animations.  My favorite is the Peaucellier straight line mechanism.  You will find a table of 16 or so animations at his site:

Bennett Linkage

Linkage animations on synthetica

This link connects to a web-page with a number of linkage animations. There are several planar four-bar linkages, several spherical four-bar linkages, and an example of a spatial four-bar linkage called a Bennett linkage that is shown below. This page also includes a number of spherical linkage animations generated by students some years ago. (UCI Robotics and Automation Lab)

This animation was generated by HaiJun Su using POV-Ray. It is a Bennett linkage designed to guide the coupler linkage through three specified task positions:

Spherical Car Door

Spherical eight-bar linkage for a car door

This spherical eight-bar linkage was designed by GimSong Soh to guide a car door from the side to the top of the vehicle. This animation shows the versatility of movement provided by these linkages. (UCI Robotics and Automation Lab)
