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:

Materials Selection in Mechanical Design

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

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)

Colorado Videos

Mechanisms videos at Colorado State

Prof. David Alciatore has a large number of videos illustrating machines, physics principles and billiards, including high speed videos.  Video demonstrations of mechanisms can be found at the following site as well as links to much more:

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)

Chris Sangwin

C. J. Sangwin’s linkage movies

Chris Sangwin has a nice collection of linkage movies at How round is your circle?.

Particularly nice are the straight line mechanisms such as Hart’s second straight-line mechanism.

His example of the Sarrus linkage is also found on YouTube:

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:
