CTA showcased the Aerostream project at the 2025 Seville Science Fair , held from April 22 to 24, 2025 , and organized by the Sociedad Andaluza para la Divulgación de la Ciencia (SADC) . The event took place at FIBES and attracted over 30,000 visitors from schools and families across Andalusia . At the Seville Space Forum stand, attendees experienced interactive demonstrations focused on aerospace innovation , sustainability , and education , all presented through the Aerostream project .

Coinciding with the Short-term Visit of the project, CTA hosted a workshop on the co-creation of European proposals at its Seville headquarters. Held in a hybrid format to include remote participants, the session explored the entire proposal development process—from idea generation to project management and signing with the European Commission. With active participation from the consortium, the workshop reinforced AeroSTREAM’s commitment to strengthening European research through collaboration, knowledge sharing, and forward-looking innovation.

The European project AeroSTREAM recently engaged students at the Juan de Mairena Institute in Seville during a STEM-focused workshop aimed at showcasing the potential of careers in science and technology. Marta Macías , innovation consultant at CTA and project partner, introduced over 50 students and teachers to AeroSTREAM’s mission—advancing autonomous aerial systems through international collaboration between Croatia, Bosnia and Herzegovina, Spain, the Netherlands, and the Czech Republic. She highlighted the project as a real-world example of innovation, cross-border cooperation, and opportunities in emerging tech sectors. The session also promoted the role of women in STEM , encouraging female students to pursue science careers without barriers. Students responded with great interest, particularly in aerial robotics, with many expressing a desire to study physics or robotics.

Students and professors from Prva gimnazija Varaždin (PGV), covering all four high school grade levels, recently visited the Faculty of Electrical Engineering and Computing (FER) in Zagreb, with a special focus on the work of the Laboratory for Robotics and Intelligent Control Systems (LARICS). The visit featured engaging lectures and demonstrations by LARICS researchers. Robert Milijaš, M.Eng., showcased some of the advanced equipment used in their ongoing robotics research, while Associate Professor Tamara Petrović, PhD, delivered a captivating lecture on multi-robot systems. The highlight of the visit was a live demonstration by researchers Marijana Peti, M.Eng., and Marin Maletić, M.Eng., who flew small aerial vehicles in front of the students, offering a real-world look at robotics in action. This visit aimed to inspire students and spark greater interest in science, technology, engineering, and mathematics (STEM). It was co-financed by the Ministry of Science, Education and Youth through the Innovative STEM Learning for a Digital Future project, carried out in collaboration between PGV and FER, as well as through the Interreg projects HyEfRe and Danube Indeet .

Protostar Labs from Croatia recently completed a short-term visit to #CATEC as part of the #AeroSTREAM project. During their visit, the team, specializing in computer vision, AI, and UAVs, collaborated on the detection and recognition of aircraft and drones using images. Their work included synthetic data generation, machine learning model training, and the deployment of models to FPGA, contributing to advancements in autonomous aerial systems applications.

The European project AeroSTREAM played a leading role at Transfiere 2025 , the foremost European forum for knowledge transfer and R&D&I, held from 12 to 14 March at FYCMA (Trade Fair and Congress Centre of Malaga). Participating alongside CTA (Technological Corporation of Andalusia) , a golden partner of the event, AeroSTREAM showcased its growing impact in the field of autonomous aerial systems.

Luka Kramarić recently participated in a short-term research stay at the Group of Robotics, Vision, and Control (GRVC) Lab at the University of Seville. During this stay, Kramarić conducted experiments exploring UWB-based localization for unmanned aerial vehicles (UAVs). Specifically, he worked with a Crazyflie 2.1 nano-UAV equipped with a DWM1000 UWB module, utilizing a set of fixed UWB anchors and the two-way ranging (TWR) protocol to measure distances and estimate the UAV's position in real time. The research focused on evaluating how different factors, such as anchor placement, elevation, and angle, influenced ranging accuracy.

A new paper has been published in Sensors (Vol. 25, Issue 4) by researchers from SAXION University of Applied Sciences , University of Zagreb (FSB) , Karlovac University of Applied Sciences , and Zagreb University of Applied Sciences . The paper, titled "Multirotor UAV—A Multidisciplinary Platform for Teaching Mechatronics Engineering" , was authored by Denis Kotarski , Marko Pranjić , Ayham Alharbat , Petar Piljek , and Toni Bjažić . It discusses how PX4-based drone systems and MATLAB Simulink can be utilized to enhance practical learning in undergraduate mechatronics education.
