Rectilinear eight-bar linkage
This animation was prepared by Yang Liu for a linkage designed by Kaustubh Sonawale. The eight-bar linkage guides the platform in the approximation to rectilinear motion.

Six-bar linkage with rectilinear moving link
This is an animation of a Watt I six-bar linkage with a translating link that does not rotate (select the video to begin the animation). This is obtained using GeoGebra to execute a construction described by E. A. Dijksman in his book Motion Geometry of Mechanisms.

Kinematics and Polynomials–available on a Mac
Until yesterday, my iBooks Introduction to Theoretical Kinematics and Kinematics and Polynomials were available only on the iPad, but now with OSX Mavericks they are available on any Mac. Please give it a try. You can download a sample at this link: Kinematics and Polynomials sample.
Preparing for the California Challenge
Some of the cars being prepared for the California Challenge on Saturday, October 5, 2013 at the Orange County Great Park.
Mechanical characters
Disney Research guides two degree-of-freedom open chains using the coupler curve of a geared five-bar linkage to obtain geared seven-bar and nine-bar linkages, which they use to move the front and rear legs of their Cyber Tiger. By connecting the driving gears of the four legs, they obtain a one degree-of-freedom system that animates the […]

The California Challenge is an energy efficiency time trial. […]
Six-bar Linkage Design for Mechanical Computation
Our paper Numerical Synthesis of Six-bar Linkages for Mechanical Computation provides the mathematical theory that underlies the synthesis of a six-bar linkage with an input-output relationship that approximates a specified function. This describes how the Stephenson III six-bar linkage that sets the elevation for a ballistic trajectory was designed.
