FER day at MIOC

fer_miocFER day was held at XV. gymnasium (MIOC) in Zagreb on March 2nd to introduce school’s students to activities and laboratories at FER. LARICS was represented with a booth where we had a Nao robot performing its usual dance routine and wowing the audience, and a Pioneer demonstrating its SLAM abilities to the students. Our colleagues from LABUST represented subCULTron project with an aPad and two aMussels, bringing attention to another aspect of robotics.

LARICS at the FER Job Fair

job fair fer larics laboratoryJob Fair is the event organized by FER seen in the eyes of students as a unique opportunity for them to meet potential future employers. This year FER was present also as an employer offering a number of vacant positions, from doctoral to postdoctoral. Ever since our postdoctorand Domagoj Tolic left to Dubrovnik, LARICS is offering a free postdoctoral position at the project ADORE. Therefore, Prof. Zdenko Kovacic and Dr. Damjan Miklić took part in the FER Job Fair and at the FER’s stand presented the ADORE project to the interested parties and distributed leaflets hoping to attract the right person for the project.

LARICS also co-organized an open door event during Job Fair alongside Laboratory for Underwater Systems and Technologies (LABUST) and the Laboratory for Autonomous Systems and Mobile Robots (LAMOR) as part of the robotics@fer.hr brand.


European Robotics Week on FER

Since 2014 the European Robotics Week has become a major robotics event in many places all over Europe. The coordinator for Croatia is LARICS postdoctorand dr. Matko Orsag. LARICS, together with other two FER robotics laboratories, LAMOR and LABUST, opened widely laboratory doors to visitors and prepared several demonstrations of various robotics equipment for air, ground, and under water operation.

NAO robots hosted aspiring young mathematicians

raddarAs part of the RADDAR festival, organized by the XV high school of Zagreb and the Faculty of Electrical Engineering and Computing (Prof. Vesna Zupanovic), LARICS people (Prof. Zdenko Kovacic, Dr. Damjan Miklic, Frano Petric, Anja Babic, and Kruno Hrvatinic) prepared three performances with a pair of NAO robots, who showed off their dancing moves and perception skills to almost 90 primary school kids interested in maths. The kids were also challenged to a series of exciting robot-human tic-tac-toe duels. The final score was in favor of humans, but the robots are catching up fast! As expected, many cell-phone videos were taken and immediately shared with friends on popular social networks.

Maja Varga held the lecture “Increasing autonomy of the fixed wing robots”

Mmvargaaja Varga, LARICS young scientist, currently a Ph.D. student at the EPFL Lausanne, Switzerland held a very interesting lecture about the fixed wing robots being used in numerous outdoor applications, such as providing area coverage, mapping applications, providing communication relay, environmental monitoring. In many of those applications, exact path of the robot is preprogrammed and mission is usually planned in advance. Each flying robot needs dedicated human operator to provide safe flight. The question arises, what is  necessary to add to the functionality of fixed wing robots to make them more autonomous, reactive and less dependent on the human intervention. In her talk, she presented control methodologies to overcome unicycle dynamics of the fixed wing flying robots to make the platforms more reactive and control architecture to enable switching between different flying robot behaviors.

Nikola Rosic successfully defended diploma thesis

LARICS student Nikola Rosic succesfully defended his diploma thesis entitled “Control system for a 2 DOF platform”. The task Nikola successfully solved was to develop a nonlinear dynamic model of a 2 DOF platform using Matlab. Then he developed a linear control program for positioning of a ball on the real laboratory platform. The positioning was accomplished by controlling two servo motors using the information from a mounted video camera.

Miroslav Kovac successfully defended diploma thesis

LARICS student Miroslav Kovac succesfully defended his diploma thesis entitled “Modeling, simulation and control of city traffic”. It is well known that traffic jams are part of our everyday life in big cities. Miroslav attempted to create a nonlinear model of city traffic regulated by traffic lights, taking into account the number of vehicles and their speed. The whole work was done using Matlab and the simulation results showed very useful and interesting relations between the frequency of vehicles and the duration of traffic lights` turn on-turn off intervals.

LARICS student Luka Kalinovcic has qualified for the World Student ACM-ICPC competition

It is our great pleasure to inform you about great success of the Zagreb University Informatics teams at the CERC 2007 – The 2007 ACM Central European Regional Contest that was held in Prague, November 09-12, as a part of the International Collegiate Programming Contest. Among 67 teams from 34 Central-European universities, the first Zagreb team led by third-year LARICS student Luka Kalinovcic won the second place and thus, qualified for the world competition of 80 world best teams, that is going to be held at the Banff Springs University, Alberta, Canada. The second Zagreb team, whose member was LARICS student Davor Jerbic, won the fifth place, which is also an excellent result.

Three LARICS students have become diploma engineers

It is a great pleasure to announce that three LARICS students, Ivana Palunko, Mario Dogan, and Danijel Milisic successfully defended their diploma works. Ivana worked on modeling, simulation and control of a helicopter. Mario used genetic algorithms to generate control sequences for a straight and circular motion of a hexapod robot. Just to give you a flavour of what has been done, you can see a short movie (13 MB) showing the straight-forward motion of the hexapod robot with the blocked front right-hand leg. Danijel developed an application for face recognition using a low cost web camera.

Nine LARICS students have become diploma engineers

It was a day to remember! Nine LARICS students (eight of them advised by Stjepan Bogdan) successfully defended their diploma works: Robert Pavlovic, Vedran Bobanac, Borna Buntic, Andrija Ersek, Matko Medenjak, Sasa Oreskovic, Tamara Petrovic, Domagoj Tolic, and Tomislav Vlah. There is no need to mention that all of them did excellent jobs. Tamara graduated with highest honors – her score through all five years of studying is unbeatable – 5.0 ! Others were not far from that. It will be interesting to see whether we will have such extraordinary graduation day again. We wish all of them have great professional careers!

LARICS students Tatjana Djebro, Ivana Fazinic and Vedran Sesar have become diploma engineers

Three LARICS students, Tatjana Djebro, Ivana Fazinic and Vedran Sesar, successfully defended their diploma works. Tatjana built a mathematical model of a Zeppelin type of a blimp and designed an LQ controller for navigation control. Ivana designed a fuzzy controller for control of a 2 DOF laboratory aeroplane by using fuzzy Lyapunov stability criteria and fuzzy numbers. Vedran added a client application to Leonardo program which enabled control of SCARA robot Kiwi via TCP/IP. Now it is possible to plan trajectories by using Leonardo, send references to Kiwi and execute the trajectories.

LARICS student Sinisa Dujmovic has become a diploma engineer

A LARICS student Sinisa Dujmovic successfully defended his diploma work entitled “Control of SCARA robot Kiwi from Matlab via TCP/IP”.
