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.

The doors of the Koenigsegg CCX open using the “dihedral synchro-helix door actuation” system. You can see this movement on the video
