Archway

Prototype spherical archway

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.

Drawer Deploy

Six-bar linkage prototypes

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.

This articulated model horse is by the artist James Watt.

A kit for this device and other designs can be found on his web-site: http://clockworkrobot.com/

Koenigsegg Door

Koenigsegg door system

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

Mondo Spider

Mondo Spider walking machine

This walking machine known as the Mondo Spider.

 The leg of the mondo spider has the topology known as a Stephenson six-bar and is described in US Patent 6,260,862 awarded to Joseph Klann. Access it through the link:

Jansen Strandbeest

Theo Jansen’s walking machine

Theo Jansen builds amazing walking machines.
Each leg is an eight-bar linkage. The Wolfram Demonstration Project models this linkage in a Mathematica notebook. See the link:
