Animations of linkage movement.

Convertible Hardtop

Hardtop Convertible Linkage

This SolidWorks animation of the drive linkage for a hardtop convertible was prepared by Oscar Alonso from U.S. Patent No. 7014247 (Dilluvio) and previous references.

Six-bar Retrieval Linkage for an ROV

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.

Dumping Linkage

Six-bar Trash Dumping Linkage

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:

Shelf Deploy

Six-bar Shelf Linkage

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

Monitor Linkage

Monitor Six-bar Linkage

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.

This is a SolidWorks animation of this six-bar linkage:

This is a video of the prototype:

Mechanism Generator

SolidWorks Mechanism Generator

Mechanism Generator

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.

Monitory Deploy

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)

Deployable Arch

Deployable archway

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)

Shelter Deployment

Stackable fold-up emergency shelter

Mikhail Zhuk animated this design concept for an eight-bar linkage to deploy a collapsible emergency structure. A physical prototype is under development. (UCI Robotics and Automation Lab)

Jansen and Klann Legs

Comparison of Klann and Jansen leg linkages

Joseph Klann provided a useful comparison of the leg designs for the Mondo Spider and Theo Jansen’s Strandbeest at this unfortunately dead link: http://www.mechanicalspider.com/comparison.html. I keep in here in case he brings it back.

Here is an excellent web page about the Klann and Jansen leg mechanisms, as well as other leg designs: Dog Feather Designs.

This article compares the leg designs:  Mechanical Spider Using Klann Mechanism

This is a youtube video prepared by William Thielicke that illustrates the two leg mechanisms.
