Mathematica File for Linkage Synthesis

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 theory. In my courses students generate their own notebooks like this for the analysis and synthesis of various linkages. The program is not optimized in any way.

This particular notebook does provide a new capability. It uses a randomized search in tolerance zones near the required task positions to find linkages that do not have well-known defects. Cut and paste the text file output into our Mechanism Generator software to automatically generate a SolidWorks model of the linkage and task.

Convertible Hardtop

Hardtop Convertible Linkage

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.

Six-bar Retrieval Linkage for an ROV

This six-bar linkage was designed to extend from the body of an underwater ROV to retrieve and stow objects positioned by a robotic arm.

Dumping Linkage

Six-bar Trash Dumping Linkage

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:

Shelf Deploy

Six-bar Shelf Linkage

This six-bar linkage is designed to move a shelf from a position down and forward to a stowed position up and away.

Monitor Linkage

Monitor Six-bar Linkage

This video shows our latest model for the six-bar linkage that deploys and stows a television monitor.  This was designed and built by Eddie Lee, Peter Lim, Khemara Tep and Kevin Hung.

This is a SolidWorks animation of this six-bar linkage:

This is a video of the prototype:

2010 FSAE California

2010 Formula SAE California

The Formula SAE California collegiate race car engineering competition opened June 16, 2010 at the Auto Club Speedway in Fontana, CA. Student built racecars from all over the world can be seen in photos from this first day of the event. Here is a link to photos of the first day and a link to the 2010 event guide

Pictures from Day 2 can be found at the SAE SoCal facebook page.

PIctures from Day 3 are now available as the Facebook album.

The results are available at the link FSAE California results.

Autonomous Table Soccer at UCI

The student project for UCI’s MAE 106 mechanical systems laboratory uses a pneumatic kicker to deflect two balls away from its own goal and push them toward the opponents goal.

My link to a video of Theo Jansen’s walking machines seems unreliable, so it is best to go directly to the source: Theo Jansens Strandbeest site
