This six-bar linkage was designed to extend from the body of an underwater ROV to retrieve and stow objects positioned by a robotic arm.

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:

This is a video of the operation of the prototype:

This six-bar linkage is designed to move a shelf from a position down and forward to a stowed position up and away.

This video shows our latest model for the six-bar linkage that deploys and stows a television monitor.  This was designed and built by Eddie Lee, Peter Lim, Khemara Tep and Kevin Hung.

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)
