This rice transplanter selects seedlings from the hopper and plants them into the ground using a four-bar linkage designed by Mark Plecnik.

Mark Plecnik designed this spatial 5SS steering linkage to increase the track and increase the camber as the vehicle turns.

We have a trial version of our Mechanism Generator 2.0 software available. MechGen 2 reads five task positions of a moving part in SolidWorks and generates a set of linkages that approximate the positions within specified tolerances. An animation previewer shows how each linkage moves. Select one and MechGen 2 generates the solid model of the linkage.

This video demonstrates the operation of MechGen 2:

This is the result of excellent work by Alex Arredondo and Kaustubh Sonawale.

400 seniors in majors across UCI’s Henry Samueli School of Engineering presented posters describing over 70 senior projects. Over 140 volunteers from Engineering student clubs set-up, cooked, served, and cleaned-up the BBQ in UCI’s Engineering Plaza.

This spherical four-bar linkage concept by Kaustubh Sonawale guides the wings of the Icon A5 in the movement shown in the animation.

This is a spherical four-bar linkage concept by Kaustubh Sonawale designed to fold the wings of an Icon A5 small aircraft.

Kaustubh Sonawale designed this four-bar linkage to move a truck spare tire from a stowed position to the deployed position.

This site has photographs of a large number of devices used to teach physics. It is fascinating.
