Retractable handle
This six-bar linkage was developed at the request of a designer who wanted the handle to move in and out along a circle, while the linkage and attachments were located in the rectangle. This linkage designed by Kaustubh Sonawale seems to meet his needs.

Bolt Insertion Six-bar Linkage
This linkage was designed to guide a powered screw driver through a specified set of locations to automatically insert and tighten bolts. The design is achieved by constraining an RPR serial chain by adding two RR dyads. The work is a collaboration between Kevin Hung and Mark Plecnik.

Rice Transplanter Six-bar
This is a revised version of the rice transplanter linkage designed by Mark Plecnik. It uses an RPR chain to provide the basic movement, which is then constrained by the addition of two RR dyads. The result is a six-bar linkage that provides a more direct movement from selection of the seedling to insertion in the ground.

Spherical Four-bar Linkage Design: Mech Gen 4
This version of Mechanism Generator uses five orientations of a moving body to design a spherical four-bar linkage. As with other versions of Mech Gen the system searches in tolerance zones around the task positions to find a number of useful designs. This is more good work by the team of Alex Arredondo and Kaustubh Sonawale.
