The student robotics organization Vortex NTNU has unveiled its most advanced autonomous underwater vehicle to date, Nautilus. The launch represents more than a new competition platform, it marks a clear shift toward full-scale systems engineering and long-term operational capability. The project has been underway since summer 2025, with development formally starting in September. What began as early concepts has now materialized into a fully integrated subsea system. “It’s not long ago this was just sketches,” says Vortex leader Andreas Skagen.

Central to that ambition is the introduction of a complete development lifecycle, spanning from initial requirements through concept development, detailed design, testing, and finally operational deployment. “This year we have established a full design cycle, from requirements to operations.” Photo: Lars Bugge Aarset/Fremtidens Industri Building an organization, not just a vehicle This shift is also reflected organizationally. Vortex has expanded beyond its traditional engineering focus, introducing dedicated teams for administration, logistics, and branding. The result is a more professionalized structure that supports increasingly complex projects. At the same time, the strategic direction has evolved. While international competitions such as the RoboSub competition remain a key arena, the ambition now extends further. “In addition to competitions, we want to build a permanent operational capability,” says Skagen.

The system integrates navigation, sensor fusion, and control algorithms to execute advanced mission profiles, including inspection, object recognition, and intervention tasks. Yatavi Suresh.

The goal is to complete complex mission tasks fully autonomously.” These tasks reflect real-world subsea challenges. “The vehicle needs to navigate around pipelines, scan objects, dock on a platform, and use a gripper to manipulate things like valves, all happening through vision systems and autonomy.” She also highlights how the system is developed across disciplines within the team: “Across Vortex, hardware and software, we work together to make this happen.” Photo: Lars Bugge Aarset/Fremtidens Industri Industry collaboration driving capability That maturity is closely tied to collaboration with industry. Vortex relies heavily on partners for both technology and expertise, working with companies such as Water Linked, Nortek, Kongsberg Discovery, and sensor supplier NORBIT, all part of Ocean Autonomy Cluster.. Access to new equipment has also expanded the system’s capabilities. Suresh points to the integration of sonar as a key step forward: “We now have sonar technology we haven’t used before. It’s a new challenge, but also an opportunity to learn and develop alongside the technology. ”We couldn’t have done this without your support, not just funding, but mentoring, tools and guidance,” Skagen adds.

You should be excited about your future.” Henrik Porten Hemnes, Water Linked and Christopher Strøm, Nortek, Photo: Lars Bugge Aarset/Fremtidens Industri Christopher Strøm, working with sensor fusion at Nortek, points to the rapid evolution of subsea sensing technologies as a key enabler. “We make sensors that can measure moving things underwater very accurately,” he says. “Navigation is becoming more and more important.” He highlights how the industry has moved from large, standalone instruments to compact, integrated systems. “Earlier systems were bulky, now everything is becoming smaller and more integrated.” Seeing those same technologies applied in Nautilus is something he looks forward to. “I’m looking forward to seeing this in action in competition.” Photo: Lars Bugge Aarset/Fremtidens Industri A pipeline into the maritime industry For Kongsberg Discovery, the engagement goes well beyond technology development. The company has collaborated with student environments like Vortex for nearly a decade, both supporting projects and recruiting talent. “It’s an impressive piece of work, the biggest one so far,” says R&D Manager Tor Einar Gauslaa.

Over the years, more than 35 employees have been recruited directly from similar environments, with additional hires coming through internships and project collaborations. “We’ve hired dozens of people from this environment,” Gauslaa says. The reason is straightforward. “What you learn here, working across disciplines, is exactly what we need in industry.” He emphasizes that modern maritime technology depends on the integration of software, hardware, and systems engineering. “That’s why we value technical student organisations so highly. We try to support you with equipment, but also with knowledge and collaboration,” Gauslaa adds. Photo: Lars Bugge Aarset/Fremtidens Industri. Reflecting broader industry trends The unveiling of Nautilus reflects broader shifts shaping the maritime sector: increasing system complexity, tighter integration of sensors and autonomy, and a growing need for interdisciplinary engineering competence. At the same time, it highlights the evolving role of student organizations, from competition-focused teams to structured engineering environments with clear industry relevance in subsea operations, ocean technology, and defense-related domains.

But the longer-term ambition is already clear. “It’s not long ago this was just sketches,” Skagen says. Now, it is a fully operational system, and a tangible sign of how quickly the next generation of maritime robotics engineers is closing the gap to industry.
