DESIGN INNOVATION

21st Century Kinematics

21st Century Kinematics

The NSF Workshop on 21st Century Kinematics at the 2012 ASME IDETC Conference in Chicago, IL on August 11-12, 2012 consisted of a series of presentations and a book of supporting material prepared by the workshop contributors.

The book is now available at amazon.com: 21st Century Kinematics–The 2012 NSF Workshop.

And here are the seven primary presentations given at the workshop.

  1. Computer-Aided Invention of Mechanisms and Robots. J. Michael McCarthy, Professor, University of California, Irvine.
  2. Mechanism Synthesis for Modeling Human Movement. Vincenzo Parenti-Castelli, Professor, University of Bologna.
  3. Algebraic Geometry and Kinematic Synthesis. Manfred Husty, Professor, University of Innsbruck.
  4. Kinematic Synthesis of Compliant Mechanisms. Larry Howell, Professor, Brigham Young University.
  5. Kinematics and Numerical Algebraic Geometry. Charles Wampler, Technical Fellow, General Motors Research and Development.
  6. Kinematic Analysis of Cable Robotic Systems. Vijay Kumar, Professor, University of Pennsylvania.
  7. Protein Kinematics. Kazem Kazerounian, Professor, University of Connecticut.

Colleagues joined in with two additional presentations:

Many thanks to the contributors and the attendees for an outstanding workshop.

Update: The presentation links have been fixed.

Archway

Prototype spherical archway

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.

Drawer Deploy

Six-bar linkage prototypes

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.

Automotive components

Chris Longhurst has assembled a number of descriptive articles and illustrations about automotive engines, transmissions, steering, suspensions, brakes and tires on his site http://www.carbibles.com
