15940758_1830404410547092_3171236138417000760_nFor the first time FIRST LEGO League was held in Croatia, at FER on January 14th 2017. The league runs for 18 years and is held in 80 countries around the world, and thanks to organization of Croatian Robotic Association, Croatia is one of them. During the opening ceremony NAO robot performed one of his distinctive dances and wowed the audience.

Competition consists of multiple parts (core values, scientific project, robot game, mechanical design) and our Prof. Zdenko Kovačić and Barbara Arbanas were the judges of the technical part. This year 11 teams of children aged 9-16 applied and we expect even more in the upcoming years!

subCULTron “feature freeze” workshop at FER

IMG_4105LARICS and LABUST organized H2020 project subCULTron workshop under the title of “stress test workshop” at UNIZG FER on 9 – 13 January 2017 with all project partners representatives.

Overall goal of the workshop was to feature freeze new electronic design for mass production of 100+ aMussel units. Extensive testing on three newly produced aMussels in the pool as well as out of it validated the design and provided us with the data to make minor adjustments before taking the next step.

Winter school on AI and Robotics

IMG_3798Barbara Arbanas attended “Lucia 2016 – 3nd PhD school on Artificial Intelligence and Robotics”, held in Örebro, Sweden on December 12-16, 2016. The school provided a unique training and human experience. Lecture topics covered technologies at the forefront of research in AI and in Robotics, while some of these were applied through hands-on exercises on real robots. It also showed to be the opportunity to discuss the research work with top level scholars as well as other students, and to extend networks. Barbara also presented project subCULTron in an interactive poster session.

New book chapter on automated warehousing systems published by ASTM International

WeASTM Book cover are pleased to announce that the book chapter “Harmonization of Research and Development Activities Toward Standardization in the Automated Warehousing Systems” co-authored by Z. Kovačić, M. Butler, P. Lista, G. Vasiljević, I. Draganjac, D. Miklić, T. Petrović, and F. Petric has been just published in the book Autonomous Industrial Vehicles: From the Laboratory to the Factory Floor, Editor(s): R. Bostelman (NIST); E. Messina, ASTM International, pp. 106-128, April 2016 (available on-line: DOI:10.1520/STP159420150050). In this chapter, we describe some ideas of robotic system standardization based on the recently concluded research and development processes in the European FP7 project named EC-SAFEMOBIL, which was focused on estimation and control technologies for safe, wireless, high-mobility cooperative systems. In the given analysis of possible standardization of automated warehousing systems, we elaborate on ideas on how to overcome evident gaps between academic achievements and viable industry practice. Paying particular attention to process and development standards, as well as function-specific standards, we describe our view of reaching new standards in automated warehousing systems, particularly with a number of deployed automated guided vehicles (AGVs).

Goran Vasiljevic defended the topic of his doctoral dissertation

In front of the assessment committee (Prof. Stjepan Bogdan, Prof. Zdenko Kovacic, and Prof. Ivana Palunko), LARICS PhD student Goran vasiljevic mentored by Prof. Kovacic successfully presented and defended the topic of his doctoral dissertation entitled „High precision markerless localization of mobile robots in indoor industrial environments“. The Committee agreed upon expected scientific contributions and thereafter, the Faculty Council and the Technical Committee of the University of Zagreb should still approve the given topic proposal. The aim of this doctoral dissertation is to extend the current state of the art in the indoor industrial environments and eliminate limitations present in current systems due to the use of marker-based localization solutions. Contribution is intended to be achieved by development and implementation of new localization methods, in order to achieve the accuracy required within specific industrial applications that can only be achieved using markers. Developed new methods are planned to be implemented on a real autonomous forklift and their performance validated in realistic indoor industrial conditions (automated warehouses).

LARICS featured in Jutarnji list

On May 23rd, Jutarnji list, one of the most prominent Croatian newspaper published an article about subCULTron project. Featured on the front page, it encompasses an extensive interview with our own Prof. Stjepan Bogdan and Asst. Prof. Nikola Mišković from Laboratory for Underwater Systems and Technologies, LABUST. The article provided a great visibility to the project and yielded many positive reactions. Other LARICS members working on subCULTron project are Tamara Petrović, Goran Vasiljević and Barbara Arbanas.


larics fer laboratory icra 2016This year’s ICRA conference (IEEE International Conference on Robotics and Automation) held from 16th until 21st of May 2016 in Stockholm, Sweden was attended by multiple members of LARICS team. Matko Orsag, Tamara Petrović, Karlo Griparić, Tomislav Haus, Edin Kočo, Antun Ivanović, Barbara Arbanas and Marko Car participated in various conference activities.

In a short three minute presentation, Barbara presented the paper Aerial-ground robotic system for autonomous delivery tasks and was later joined by her coauthors Matko, Tamara, Tomislav, Antun and Marko in a forty minute interactive session, where conference attendees could ask questions about the presented paper in more detail.

Matko, Tamara, Karlo and Tomislav took part in “Nature vs. Nurture in Robotics” workshop, where they presented ASSISIbf project with a poster accompanied with a short presentation. They also attended a panel discussion on the same subject.

Conference was an overall success as we were able to present our laboratory to the community, as well as introduce the brand which joins forces of three robotics labs from our faculty — LARICS, LABUST (Laboratory for Underwater Systems and Technologies) and LAMOR (Laboratory for Autonomous Systems and Mobile Robots).

LARICS visited the Technical faculty and Alfanum in Novi Sad

One of the key components in the interaction of NAO robots and children is a vocal communicatioAlfanum_Novi_Sadn. In the protocol for diagnostics of autism adapted for NAO robots, the tasks like Call by name require vocal communication in Croatian language. NAO robots speak French and English very fine, but they do not speak Croatian. Here comes the reason why Prof. Kovacic, Dr. Damjan Miklic and Frano Petric gladly accepted an invitation to visit the laboratories of the Technical Faculty in Novi Sad and the company Alfanum, a regional leader in speech communication technologies. Thanks to the agreement to start the collaboration between two parties, our NAO robots now speak Croatian very well and  we are going to teach them to understand some Croatian vocabulary that is most often used by small children. We would like to thank Prof. Vlado Delic and Darko Pekar from Alfanum for their full openness and warm welcome.

LARICS paper is published on-line in International Journal of Advanced Robotic Systems

Paper “New Variable Passive-compliant Element Design for Quadruped Adaptation to Stiffness-varying Terrain”, written by Edin Koco, Alan Mutka and Prof. Zdenko Kovacic is now published online in the International Journal of Advanced Robotic Systems. The paper presents the design of a novel variable passive-compliant (VPC) element utilized as a lower-leg implant of a fully electrically driven quadruped robot. It is designed as a slider-piston mechanism which ensures that the force produced during a foot-ground contact is directly perpendicular to the contact surface of an actuated revolute spring. In this way, by altering the stiffness of quadruped legs in a closed-loop manner, the VPC element enables the quadruped robot to adapt to varying terrain characteristics, ensuring a constant hopping frequency over a wide range of terrain-stiffness variations.
