Sphinx and Sphere VR and the History of Kinematic Synthesis

Sphinx and Sphere VR and the History of Kinematic Synthesis

Our Sphinx software was the first computer-aided design system for spherical linkages. It used IRIS system by Silicon Graphics. Collaboration with Judy Vance lead to a Virtual Reality version of this design system.

This is a link to the description of this research at Iowa State University.

This video shows the operation of these two design systems;

KinSyn and the History of Kinematic Synthesis

KinSyn and the History of Kinematic Synthesis

My first experience with computer based kinematic synthesis was a 1982 presentation by Roger Kaufman of his KinSyn linkage design software on an Apple II microcomputer. This is a link to his description of his experience in those early days of computer-aided design of linkages.

His paper that describes this software can be found here. The photos are a terrific look into the computer technology in the 1970’s.

Here is a video that describes the operation of KinSyn, which I find to be an impressive integration of kinematics calculations in the background with a useful graphical presentation of information to the designer. I have to say that the graphical display was impressive in its day.

Kinematic Synthesis of Mechanisms Title Video

Kinematic Synthesis of Mechanisms Title Video

This animation was prepared by Yang Liu of a walking machine designed by Mark Plecnik. This is the title video for my new book Kinematic Synthesis of Mechanism: A project based approach.

The book contains 82 color figures and 30 animations. It is available as an iBook and a Kindle Interactive book on April 7, 2019.

The print version is available now on Amazon.com and the animations are available on the Kinematic Synthesis of Mechanisms YouTube Playlist.

Micro-Linkages for a Compliant Material

Micro-Linkages for a Compliant Material

Lucas Shaw and Prof. Jonathan Hopkins show the micro-architecture of an actively compliant material. Micro-actuators within the unit cells of an assembly are coordinated to reshape the assembly as desired. This was presented as part of the 2015 ASME Design Engineering Technical Conferences in Boston, MA, August 2-5. The video below shows what this assembly can do.

An Interesting Planar Robot at Laval

An Interesting Planar Robot at Laval

Students of Prof. Clement Gosselin at the Laval University Robotics Laboratory demonstrate a four-degree of freedom planar robot. I particularly like the demonstration of its use as a gripper that does a cartwheel just for fun.
