I am pleased to say that the second edition of my book, Geometric Design of Linkages, is now available, and I have to express my sincere gratitude to my co-author GimSong Soh, who helped make it happen. You can find more information at the Springer Verlag web-page, GDL on Springer.com. It is also already on […]
This shows the operation of our Mathematica notebook for five-position synthesis of a four-bar linkage. The link to download and try this notebook is on our Linkage Synthesis page.
This is a draft of my editorial on 21st Century Kinematics for the Journal of Mechanisms and Robotics. It is a follow-up to my previous editorial on Kinematics, Polynomials and Computers. I would welcome your feedback.
The 2011 UCI Energy Invitational will be at Willow Springs International Motorsports Park on March 22-23, 2011. The Streets of Willow Springs will be set up with a highway, autocross and staged idle sections to challenge the energy usage of all types of vehicles. How far can your vehicle travel in an hour on this […]
Select this link to the .pdf of Kinematics, Polynomials, and Computers–A Brief History, which is a summary of the history of the kinematics of mechanisms and robotics with a focus on the challenge of solving the polynomial equations that arise in their study. It is a draft of my February 2011 editorial for the ASME Journal of […]
This is a video on Yahoo! that shows the movement of the Convertible Hard Top of the Peugeot 407. The two side rails fold out from the back, and provide guides for the glass panels that move out to become the top.
Select this link to download our Mathematica notebook for four-bar linkage synthesis. It will download as a textfile, so delete the .txt extension, then Mathematica should be able to read it. If you have an problems, please contact me. This notebook is an example of the type of programs that I use to teach mechanism […]
This SolidWorks animation of the drive linkage for a hardtop convertible was prepared by Oscar Alonso from U.S. Patent No. 7014247 (Dilluvio) and previous references.
This compact six-bar linkage is designed to lift and dump a trash can. Eddie Lee, Peter Lim, Khemara Tep and Kevin Hung worked on the design and construction of the prototype. This is the SolidWorks animation: This is a video of the operation of the prototype:
This six-bar linkage is designed to move a shelf from a position down and forward to a stowed position up and away.
