Workshop on 21st Century Kinematics
The NSF Workshop on 21st Century Kinematics at the 2012 ASME IDETC Conference in Chicago, IL on August 11-12, 2012 consisted of a series of presentations and a book of supporting material prepared by the workshop contributors. The book is now available at amazon.com: 21st Century Kinematics–The 2012 NSF Workshop. And here are the seven […]
Mechanism and Robotics Notes
The server in our UCI Robotics and Automation Laboratory has been revived (thank you Kaustubh). This means the links to course notes and to Mathematica notebooks have been reestablished. Synthetica.eng.uci.edu now links to my web-page which needs work. A laboratory page that will replace this soon.
Rectilinear eight-bar suspension
This is a design concept for a rectilinear eight-bar suspension. It does not manage body roll but it does provide compact large travel.
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 […]
