On November 23, 2017 LARICS researcher Tomislav Haus successfully defended his doctoral dissertation and received a Doctor of Science degree in Electrical Engineering. Tomislav’s thesis was entitled “Control of multirotor unmanned aerial vehicle based on moving mass concept”. The original scientific contributions of his thesis include: (i) A method for roll and pitch control of a multirotor unmanned aerial vehicle based on the moving mass concept, (ii) Analysis of dynamical and static characteristics of a multirotor unmanned aerial vehicle with internal combustion engines and moving masses based on the derived mathematical model and parameter identification, (iii) Adaptive control algorithm for a multirotor unmanned aerial vehicle with internal combustion engines and moving masses which compensates for changes of the center of mass and moment of inertia.
LARICS part of the MORUS team (Stjepan Bogdan, Matko Orsag, Tomislav Haus, Antun Ivanović, Marko Car) spent a week in a military base in Udbina preparing the MORUS aerial vehicle powered by four internal combustion engines for the first take off. We are happy to report that the maiden flight of the vehicle took place on November 17, 2017. In the final experiment, the vehicle was piloted through RC controller, with height, yaw, roll and pitch manually controlled by the pilot. This first flight demonstrated that the concept proposed within the project is feasible. There have been many lessons learned throughout the week spent in the base, which will be used to improve the vehicle design and performance.
We participated in the lecture on Knowledge Thursday at Croatian Telecom held in their offices in Sky Tower on Thursday, November 16th 2017.

At this year’s Breaking the Surface workshop LARICS and LABUST researchers demonstrated the functionality of the underwater heterogeneous swarm developed within project subCULTron. Demonstration gained a lot of attention, and we got many interesting questions and ideas from attendees.
After the BtS workshop, FER part of the subCULTron consortium stayed in Biograd na Moru to conduct further experiments with the swarm. Experiments included aMussel drifting freely in Biograd aquatorium and monitoring the environment, implementing consensus algorithms for underwater system using scheduled acoustic communication, autonomous docking and formation control. Experiments were successful, we gained a lot of insights into the functioning of the swarm and are looking forward to working on the project goals and challenges in the following year.
Finishing the development phase of our collaboration with Croatian Telecom and Bokamobile, we deployed Croatian Telecom’s Pepper robot in two scenarios on Weekend Media Festival, held in Rovinj, Croatia on September 21-24, 2017.
In the first scenario, Pepper was the announcer of the panel talk called Stem, je t’aime: The Future is Now. Pepper was joined by Nenad Bakic, Mate Rimac, Boris Drilo, Boris Jokic and others to discuss the importance of STEM in Croatia.
The other task for Pepper was to be a host at the Croatian Telecom booth, where the robot greeted the visitors and offered them the opportunity to dance, take selfies, play a game or learn more about STEM fields.
On 15th September 2017 subCULTron consortium jointly publicly presented subCULTron project as “the world largest diving robot test” in the waters in the Venice lagoon, at the Venice Arsenal. This was the first time that journalists and the public had the opportunity to see our project in action. Journalist from whole Europe participated in the event and transmitted the news about the project. Euro news feature on subCULTron can be found here.
At the end of July 2017 an “Assembly Workshop” for project subCULTron was held at the Faculty of Electrical Engineering and Computing, with two laboratories from Zagreb participating – LARICS and LABUST. During the assembly workshop the project consortium assembled and tested 20 aMussel platforms and assembled the first aFish robot. This is the first step of the mass production of underwater heterogeneous swarm where the ultimate goal is to develop 150 robot platforms. The workshop was successful and we all enjoyed working on the platforms as well as spending quality time with members of the subCULTron consortium.
LARICS Phd student Tomislav Haus spent four weeks (mid June to mid July 2017) at United States Military Academy at WestPoint, NY, as a part of their summer internship program. He was an intern at Department for Electrical Engineering and Computer Science under supervision of LTC Christopher M. Korpela, Ph.D. Tomislav worked on vision based control and navigation of a small multirotor aerial vehicle. In particular, an algorithm has been developed which tracks QR-like markers and allows the vehicle to localize itself in a space with randomly distributed markers. The video showing the achieved results is available here.
