Tony Hawk and the Physics of Skateboarding

March 2012

Students and Tony Hawk with robot skateboard As part of the San Diego Festival of Science and Engineering, physics and dynamics behind skateboarding was demonstrated to high school students at the Carmel Valley Recreation Center. We were fortunate that Tony Hawk and his crew came to help us out, while Paul Schmitt demonstrated the art behind building skateboads with With the help of some talented undergraduate students at UCSD we were able to demonstrate the main principle behind "pumping", allowing their intial skateboard robot design to move up and down a half-pipe.

Research with Solar Turbines

January 2011

Solar Turbines logo Funded by Solar Turbines Inc., Chad Holcomb is a new student supervised by Prof. de Callafon and Prof. Bitmead. Chad will be working on aspects related to dynamic modeling and control of turbine machinery. Happy New Year!

Full Professor

July 2011

At chateau de Calavon The "Associate" can now be dropped and moved on to the more colorful position of a Full Professor. While in France, that needed to be celebrated in style with a small visit to Chateau de Calavon located in Lambesc, close to Aix-en-Provance. Dating back several hundred years and believed to be one of the earliest wineries of the de Calavon family, now owened by the family Audibert.

Sabbatical Leave

June 2011

On sabbatical leave at the GIPSA lab in Grenoble During the month of June, 2011, Prof. de Callafon made an extended visit to the the GIPSA lab in Grenoble, France working on adaptive feedback regulation problems with application to vibration control with Prof. Landau and his students Tudor-Bogdan Airimitoaie and Marouane Alma. Based on the earlier work developed under REACT (Robust Estimation for Automatic Controller Tuning), the sabatical leave at the Laboratoire d'Automatique was used to develop an extended version of REACT that also allows for weighting the (variance) of the control signal during regulation.

Picture of CARV In addition, the time was used to develop the real-time software that allowed the algorithm to be implemented on the experimental mechanical setup of the Control Active Robust des Vibrations (CARV) to validate the adaptive regulation capabilities of REACT. The develppment of this theory and the succesful application is developed into a new publication.

San Diego Science Festival

March 27, 2010

Prof. de Callafon at the SDSF The San Diego Science Festival (SDSF) 2010 Expo Day AT PETCO park brought together over 150 hands-on science activities and 12 stage performances for kids. One of the goals of the EXPO is to inspire San Diego's youth to pursue science-oriented education and careers. Our exhibit promoted COSMOS and in particular our cluster on Engineering Design and Control of Kinetic Sculptures. Many kids visited our exhibit and it was a huge success. A big thanks to Myles and Tommy helping set up our exhibit! It gave us an opportunity to communicate our excitement for engineering and science to the public. For more info, see also the article This Week @ UCSD or its PDF archive.

Seminar at Univ. of Colorado at Boulder

February 9, 2010

REACT applied on a cooling fan Following an invitation of Prof. Lucy Pao, a seminar on REACT will be given at the Dept. of Electrical, Computer and Energy Engineering (ECEE), University of Colorado at Boulder. More details can also be found in the posted on-line flyer.

COSMOS in the SERVO magazine

January 31, 2010

The Education of Budding Robotics The SERVO magazine issue of January 2010, page 71-76 features an article on our COSMOS cluster on Engineering Design and Control of Kinetic Sculptures. In the article entitled "The Education of Budding Robotics" Bryce and Evan Woolley give an overview of the experience of the students during our four week COSMOS residential program. A copy in (low res. PDF) can be downloaded here and a great opportunity to learn more about our cluster. (Reprinted with permission from T&L Publications, Inc.)

New website up and running

January 4, 2010

Our new website is finally up and running. It contains updated information on the research, teaching and publications of Prof. de Callafon. Happy New Year and the best wished for 2010!

Updated list of publications

November 30, 2009

List of Publications has been updated till 2010. This was long overdue and we are happy that we now have a full list of publications available on this website. We are currently working on including BibTeX entries to further simply the process of including a reference to our work :)

NSF CDI award - Swarms of Ocean Robots

November 10, 2009

Artist rendition of coordinated submersible drogues, courtesy of Scripps Institution of Oceanography A joint effort between Jorge Cortes (PI) at the Dept. of MAE at UCSD, Ilkay Altintas at the SDSC at UCSD, Peter Franks at SIO, Jules Jaffe at SIO and Raymond de Callafon at the Dept. of MAE at UCSD has led to funding of an NSF CDI award on Distributed Ocean Monitoring using coordinated and buoyancy controlled drogues. See also the JSOE press release or the CBS 8, San Diego news story.

New book on Realtime Controller Tuning

August 30, 2009

A new book on Realtime Controller Tuning for Periodic Disturbance Rejection and authored by Charles Kinney and R.A. de Callafon is now available. It can be purchased from Amazon and show how feedback controllers can be adopted in real-time to disturbance dynamics present during the feedback. A specific application for which this is useful is Active Noise Control where sound spectra or periodic sound components change over time.

15th IFAC Symposium on System Identification

July 30, 2009

The SYSID'09 symposium in Saint-Malo, France was a success and a great opportunity to catch up with collegues and friends. Rubbing elbows with the many System Identification experts at the conference, Dennis Bernstein was able to capture of picture of Paul van den Hof, Raymond de Callafon, Johan Schoukens and Bo Wahlberg at one of the many wine/french cheese receptions held during the conference.
