Mechanism Generator is a SolidWorks add-in that assists in generating solid models of four-bar and six-bar linkages. It designed to be used in coordination with our Mathematica design software, which is freely available.
Smitty constructed this prototype of our spherical deployable structure. It is an assembly of spherical rhombus linkages that expands to form a semi-circular structure.
Here are two videos of our first attempt to build prototypes for some of our six-bar linkage design concepts. These models were built by Steve and Justin with guidance from Smitty.
This is the six-bar linkage that guides a bottom drawer to a position that is level with the top drawer. The links were cut from aluminum and are wobbly.
This six-bar linkage deploys a television display from a horizontal position in the ceiling to a vertical position for viewing. The links are welded steel tube, and the system moves more smoothly.

Mikhail Zhuk generated this animation of Jerome Choe’s concept for a six-bar linkage that rotates a 70in TV monitor down from the ceiling around a virtual pivot positioned down from the ceiling and in front of the wall. We hope to build a physical prototype. (UCI Robotics and Automation Lab)

This animation of Jerome Choe’s concept for a spherical archway was generated by Mikhail Zhuk. Spherical rhombus elements form a foldable structure. (UCI Robotics and Automation Lab)
