Six-bar Trash Dumping Linkage

admin — Sat, 17 Jul 2010 00:00:10 +0000

This compact six-bar linkage is designed to lift and dump a trash can. Eddie Lee, Peter Lim, Khemara Tep and Kevin Hung worked on the design and construction of the prototype.

This is the SolidWorks animation:

My link to a video of Theo Jansen’s walking machines seems unreliable, so it is best to go directly to the source: Theo Jansens Strandbeest site

You can access his videos on the page: film

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.

Six-bar linkage prototypes

admin — Tue, 11 Aug 2009 02:36:29 +0000

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.

TV deployment linkage

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)
