Prof. A. J. Klein Breteler maintains an array of mechanism models at TU-Delft. Access videos of these models at the site: Linkage Models
Ilian Bonev maintains bibliography and patent databases on parallel mechanisms and much more at ParallelMIC. Access it at the link http://www.parallemic.org/
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/
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)
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)
The basic properties of robots can developed by studying planar serial chains. Select this link for my notes on elementary robotics:
Yi Zhang, Susan Finger and Stephannie Behrens have prepared an on-line introduction to mechanisms consisting of eight chapters and almost 100 figures. Access it at the link:
The slider-crank is an important mechanism with a wide range of applications. Here are my notes on its kinematic analysis.
The four-bar linkage is a basic machine component. It comes in two primary forms the 4R quadridlateral and the slider-crank. Here are my notes for the analysis of the 4R quadrilateral.
