Mikhail Zhuk generated this animation of Jerome Choe’s concept for a six-bar linkage that rotates a 70in TV monitor down from the ceiling around a virtual pivot positioned down from the ceiling and in front of the wall. We hope to build a physical prototype. (UCI Robotics and Automation Lab)
Animations of linkage movement.
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)
Joseph Klann provided a useful comparison of the leg designs for the Mondo Spider and Theo Jansen’s Strandbeest at this (archived) link: http://www.mechanicalspider.com/comparison.html.
Here is an excellent web page about the Klann and Jansen leg mechanisms, as well as other leg designs: Dog Feather Designs.
This article compares the leg designs: Mechanical Spider Using Klann Mechanism
This is a youtube video prepared by William Thielicke that illustrates the two leg mechanisms.
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.
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)
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)
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:
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:
