underwater teams. Small, agile, and affordable, Puffins are powerful tools for both
cutting-edge research and hands-on education for PhD, MSc, and BSc students.
On the surface, Puffins can move in coordinated formations. When it’s time to explore, they simply reverse their twin propellers and glide down toward the seafloor. Once there, a clever passive buoyancy system allows them to rest on the seabed for long periods, quietly collecting valuable ocean data.
Even more exciting developments are underway: enabling Puffins to communicate with each other and with other underwater systems, listen to the ocean using hydrophones, and eventually reposition themselves on the seabed. These capabilities turn Puffins into a powerful platform for experimenting with swarming marine robots and distributed ocean sensing. Already proven in real-world operations during REPMUS 2025,
Puffins show how fleets of small robots can transform the way we explore and protect our seas.
