Jiří Zemánek at the first ISAM conference at MIT

Jiří is actively participating at the first International Symposium on Academic Makerspaces (ISAM) taking place on November 13th-16th, 2016 at the Massachusetts Institute of Technology in Cambridge, MA. This is in alignment with Jiří's desire to buld a makerspace at CVUT in Prague.

Eggstatic – stroboscopic patterns for Easter eggs

Last year we did an Easter video with an EggBot drawing various mathematically generated patterns. They were inspired by equations describing Spirograph and harmonograph. The video was quite popular so we decided to take it a bit further this year. The patterns are now calculated in such a way that when rotated under a stroboscopic light of suitable frequency or when recorded by a camera, they start to animate. It is kind of zoetrope--- early device for animation.

New paper in Systems and Control Letters

Ivo Herman succeeded in getting his paper "Transients of platoons with asymmetric and different Laplacians" published in System and Control  Letters together with Peter Veerman from Portland State University. This is one of the first papers which use different Laplacian for coupling in each state. It is very difficult to analyze such systems. Therefore, they used a similarity of path and circular graphs.

We controlled an interactive Christmas tree on the lubricating tram

Last year we have built an interactive Christmas tree for the entrance hall of Czech Technical University in Prague at Karlovo namesti, this year we were asked by journalists from a technological on-line magazine Technet to put our tree on board of the service tram, so that even wider audience would enjoy it. This tram lubricates the rails all around Prague to minimize noise and is equipped with a camera streaming live video on the Internet.

Guidelines for undergraduate students who want to do a project with AA4CC

We have published fairly detailed guidelines for undergraduate students who want to do a project with us, be it a final-year undergraduate project/thesis or even an informal project collaboration in the second or third year.

Our student Jan Filip won the second prize in "ABB University Award" (http://www.abb.cz/cawp/seitp202/67b19426a3ab3b8fc1257e6e004f2d33.aspx) with his bachelor thesis „Extension of the Control System for Magnetic Manipulator with a Non-Flat Surface“ which he did in our group under supervision of Jiri Zemanek. Besides, Jan also won the award from Facebook fans.

Five journal papers out in 2015 and still counting...

Seems like a successful year so far! One paper in IEEE Transactions on Automatic Control, two papers in Electrophoresis, one paper in Automatica and one in Journal of Franklin Institute. A few more papers are in a review process and yet some more about to be submitted... This is a true harvest of the hard work in the previous years. Hurrah!

Video recording of Jiří Zemánek's presentation of MagMan platform at Technical Computing Prague 2013 conference

The video is available at http://www.youtube.com/watch?v=CHpaE2AjM-w. Jiří was invited to give the talk as the winner of the 2013 Matlab and Simulink Student Design Challenge. This is a must-see as Jiří is also sharing some experience with high performance computing. Get some frozen fish if your computer gets switched off while doing some demanding number crunching... :-)

Goodbye to Dr. Brahim Jawad after a successful postdoctoral stay with AA4CC

At the end of September 2013 we said goodbye to Dr. Brahim Jawad after a year-long postdoctoral research stay with AA4CC. As a professional physicist, Brahim worked on mathematical models for our experimental platforms for distributed manipulation. Good luck, Brahim, with your carreer!

Martin Řezáč and Zdeněk Hurák succeeded in getting the results of their applied research in the domain of robust control for inertial stabilization published in Mechatronics (Elsevier) journal.

Outdoor experimenting with inertial-on-string stability :-))

Some members of the AA4CC group have participated at experimental verification of some biological feedback controllers for inertial-on-string stabilization...:-)

Undergraduate and graduate students on internships with AA4CC

Several of our excellent undergraduate and graduate students are spending their summer vacation with us, working on assigned (and paid) projects. These are almost exclusively unrelated to their school duties. Namely, Martin Gurtner is working on design and implementation of algorithms for estimation of relative angular velocity which will outperform the currently used algorithms at low angular velocities. The motivation is to improve a performance of a friction compensator. No doubt this project is aligned with our long-term work on inertial stabilization platforms.

Jiří Zemánek lecturing at Schola ludus (an international summer school for students in science and technology) in Nove Hrady

Our doctoral student Jiří Zemánek was invited to give an overview lecture on automatic control systems at  Schola ludus (an international summer school for students in science and technology) organized by University of South Bohemia in Nove Hrady in July 2013. Jiří's presentation of our field was accompanied by experimental demonstrations using Lego Mindstorms robots, Segway, SoloWheel, AR.Drone and Sphero.

Jiří Zemánek ranked first in 2013 Matlab and Simulink Student Design Challenge

Our doctoral student Jiří Zemánek won the 2013 Matlab and Simulink Student Design Challenge. The competition consisted in submitting a video documenting the use of Matlab and Simulink for solving some research engineering problem; the videos were then evaluated by The Mathworks engineers. Jiří's video shows a laboratory experimental platform for planar manipulation with one or several iron balls by shaping the magnetic field through an array of coils.

Our undergraduate students pass their state exams and defended their final projects

Jiří Figura, Martin Gurtner, Marek Hudec, Tomáš Michálek and Evyatar Bukai have just successfully passed their state exams and defended their final projects. The first four mentioned students were graded A and thus passed with honour. This was an extremely rare concentration of bright students. Congratulations to these excellent young engineers! We feel privileged that we will have opportunities to collaborate with them within our graduate program.
