KTU Students Built a Water Drone That Could Save Swimmers from Drowning

Important | 2026-04-23

A drone that moves across water, detects a struggling swimmer, and reaches them before help arrives may sound like something from the future. However, for a group of international students at Kaunas University of Technology (KTU), this became a very real project. The Buoy Drone, developed by Armin, Vladyslav, Yevhenii and Tadiwanashe, is not just a prototype, but a response to a problem they could not ignore. “Our goal is to help lifeguards save the lives of people in danger of drowning,” Tadiwanashe explains.

The project began during their studies at KTU and was presented at Technorama 2025, where it won the Rector’s Prize. Each of the team members coming from different engineering fields – civil engineering, mechanical engineering, robotics intelligence and mechatronics – contributed to the different aspects of the invention.

Drowning Remains a Serious Issue in Lithuania

The idea for the Buoy Drone did not come from a single breakthrough moment. It started with research and a growing awareness of a serious issue. In recent years, Lithuania has recorded one of the highest drowning rates in Europe. “We were deeply saddened to discover the number of lives lost to drowning in Lithuania,” says Tadiwanashe Mkonto.

Talking to lifeguards helped them understand what is happening behind the statistics. The team spoke with the head of lifeguards in Klaipėda and other regions, who shared the real challenges they face daily. These include unpredictable weather conditions, delayed response times, and situations where people ignore safety warnings. “For us, even one life lost is one too many,” says Tadiwanashe.

From there, the goal became clear – to create something that could react immediately and support rescuers when time is critical.

The system is semi-automated. “It can patrol coastlines or lakes, detect a person in distress, and immediately alert lifeguards,” Vladyslav Dmytrenko explains. At the same time, it moves across the water towards the individual, allowing them to hold on and stay afloat until help arrives. “Ultimately, it is about reducing response time and supporting lifeguards in critical moments where every second counts,” he adds.

The team also wanted the solution to be useful beyond emergencies. As Tadiwanashe explains, they focused on making it multifunctional. “We aim to develop a system that can be used not only for rescue operations, but also for routine surveillance, rapid inspections, and even public communication via a loudspeaker,” says a KTU student. That way, it becomes something lifeguards use regularly, not just in rare situations.

Turning the idea into something tangible came with challenges. Throughout this process, the team was guided by their supervisor and mentor, KTU Assistant Professor Gediminas Monastyreckis, whose support played an important role in developing the project.

“You might have a clear idea in the beginning of what you want to build, but once you start actually working on it, you realise things are rarely as straightforward as they seem,” Armin Madadkhanivahidi says. One of the biggest hurdles for the team was learning to use industrial cutting machines from scratch under time pressure. “It pushed us to think fast and find solutions under pressure,” he adds.

Winning Was Just the Beginning

Presenting the Buoy Drone at Technorama was a chance to see how the idea works outside the classroom environment. It was not just about presenting, but also about getting feedback from people who understand both the technical and practical side of innovation.

“Technorama gave us a chance to test our idea in a real setting and see its actual potential,” Armin explains. That experience led to a moment the team still finds hard to describe.

“It was honestly hard to put into words… That moment felt unreal,” he says about winning the Rector’s Grand Prize – the top award at Technorama.

Still, what stayed with them most was not just the result. “Participating gave us the confidence to keep building and to believe that we can create things that matter in the real world,” Tadiwanashe reflects. The experience also shifted how they think about progress. It is less about getting everything right from the start and more about continuing, even when things are unclear.

For Yevhenii Sylchenko, one of the biggest takeaways was teamwork. “It showed me what real teamwork looks like – when everyone actually cares about the outcome, things just work differently,” he shares. That mutual effort is something the team sees as just as important as the technical side of the project.

The work on Buoy Drone is far from finished. Two team members are now focusing their final theses on improving different parts of the system, and the project has already been presented at a national-level event in the Lithuanian Seimas (Parliament). With more time and development, the team believes it can grow into a real product.

As Technorama 2026 approaches, it once again invites students to take their ideas further. With a prize fund of 12,000 euros and growing attention to areas like artificial intelligence, it remains a place where projects can move beyond theory and where ideas like the Buoy Drone can turn into real-world solutions.

Registration for this year’s innovation exhibition is now open to everyone who wants to present their innovations. You can register until 11 May at technorama.ktu.edu.
