Closing of yet another successful workshop was rounded off by the exciting announcement of Breaking the Surface 2025, which for the next edition is moving to the coast of Cyprus.
Challenges and CompetitionVisit Site

s at BtS 2024
For the third year in a row, participants of the BtS workshop had the opportunity to take part in the Localization challenge, organized by Newcastle University, University of Haifa, INESC-TEC, and LABUST. The task was to locate a hidden acoustic modem within a 700 by 1200-meter search area, using acoustic data, signal processing, and other engineering skills.
After an initial day of introductory presentations and familiarization with the equipment and software, each team was given 45 minutes of boat time to record data for post-processing. Teams had complete freedom in selecting their localization strategies and determining both the number and location of their boat recordings. Ultimately, Team THM from Technische Hochschule Mittelhessen emerged as the winner, based on criteria evaluating the hidden modem’s most innovative and accurate position estimate.

Following their victory at MBZIRC 2023 competition, the University of Zagreb’s Laboratory for Underwater Systems and Technologies shared a detailed demonstration at the 2024 BtS workshop. Workshop attendees explored the strategies, innovations, and behind-the-scenes work that helped UNIZG-FER secure top honors in this challenging robotics competition.
Demonstration highlights included a breakdown of the catamaran’s search and detection techniques, a look into visual servoing processes, and an overview of their docking system, which uses suction cups and hooks to stabilize the vessel. The presentation concluded with insights into the team’s drone operations, giving participants a clear view of the coordinated effort behind their successful run. This presentation gave BtS attendees an inside view of the innovation and teamwork that led to UNIZG-FER’s success at MBZIRC 2023.

OES SBC Presentations at conferences in 2024
During April 2024, several OES members actively participated at the OCEANS 2024 conference in Singapore organized by the IEEE Oceanic Engineering Society (OES) and the Marine Technology Society. Namely, Luka Mandić presented the tutorial “Data meets Model Predictive Control: From classical MPC to an online adaptive direct data-driven navigation and control of autonomous vessels.” In addition, Assist. Prof. Fausto Ferreira presented three articles: one related to the uBlueTec project, one related to an ROV simulator and one dealing with boat detection and classification using machine learning.
In September 2024, two OES PhD students, Juraj Obradović and Luka Mandić, presented their work at the CAMS conference, which was held in Blacksburg, Virginia (USA). Luka Mandić presented his work entitled “Adaptive and Robust Direct Data-Driven Controller for Surface Vessel Navigation,” where he introduced and applied an extension of the DeePC algorithm as the vessel controller. This approach aligns with the increasing trend of data-driven reference tracking in control system theory. Juraj Obradović presented his work titled “Analysis of LiDAR-Camera Fusion for Marine Situational Awareness with Emphasis on Cluster Selection in Camera Frustum,” where he introduced a method that integrates LiDAR and camera data for precise 3D object detection and tracking.

During the week of September 23-26, 2024, the work and MBZIRC competition demonstrations were presented at the 40th Anniversary of the IEEE Conference on Robotics and Automation (ICRA@40) in Rotterdam, Netherlands, with the extended abstracts titled “Autonomous Surface Vehicle for Search and Intervention in GNSS-Denied Operations” by Luka Mandić, Matko Batoš, Juraj Obradović, Natko Kraševac, Fausto Ferreira, Barbara Arbanas Ferreira, Nikola Mišković, and “Heterogeneous Multi-Robot Team for Maritime Inspection and Intervention in GNSS-Denied Scenarios” by the same group of authors together with LARICS lab members.
Barbara Arbanas Pascoal Ferreira, Matej Fabijanić, and Nadir Kapetanović attended the IROS 2024 conference held in Abu Dhabi on 14-18 October2024. Barbara presented our MBZIRC competition experiences at the Maritime Heterogeneous Unmanned Robotic Systems workshop. Matej presented his work on biofouling estimation in a poster session at the Autonomous Robotic Systems in Aquaculture: Research Challenges and Industry Needs workshop, while Nadir presented the overview of the results of the HEKTOR project at the same workshop.

Field experiments and data collection
Researchers from OES UniZg SBC have been steadily working toward advancements in situational awareness technology for autonomous boating. Recently, the team conducted a focused data collection effort as part of this ongoing project, which aims to refine and test a sensor system for improved navigation. The team, working towards a June 2025 completion, has developed a sensor rack for motorboats equipped with two cameras, LIDAR, dual GPS antennas, multiple IMUs, and AIS receiver. Over two days in early October, the team visited several marinas around Croatia’s Zadar archipelago, collecting data that will be instrumental in refining navigation algorithms. “The whole Smart Blue Tourism team prepared intensely for several weeks leading up to the planned data collection date to give us the best possible chance of actually going out to the sea and getting useful data, and it paid off!” says Matej Fabijanić, one of the researchers working on the project.
In the months ahead, this data will be analyzed to support the development of an algorithm designed to enhance situational awareness, an essential element for safe autonomous boating. This research seeks to advance both maritime technology and sustainable navigation, potentially contributing to safer and more efficient boating practices for the tourism industry and beyond.
