Animations of linkage movement.

Fred Klingener has generated a number of interesting mechanism animations.  My favorite is the Peaucellier straight line mechanism.  You will find a table of 16 or so animations at his site:

Bennett Linkage

Linkage animations on synthetica

This link connects to a web-page with a number of linkage animations. There are several planar four-bar linkages, several spherical four-bar linkages, and an example of a spatial four-bar linkage called a Bennett linkage that is shown below. This page also includes a number of spherical linkage animations generated by students some years ago. (UCI Robotics and Automation Lab)

This animation was generated by HaiJun Su using POV-Ray. It is a Bennett linkage designed to guide the coupler linkage through three specified task positions:

Spherical Car Door

Spherical eight-bar linkage for a car door

This spherical eight-bar linkage was designed by GimSong Soh to guide a car door from the side to the top of the vehicle. This animation shows the versatility of movement provided by these linkages. (UCI Robotics and Automation Lab)
