Oshen’s C-Stars are small, autonomous, and rugged wind-powered robots equipped with software that navigates them to specified locations—or keeps them stationed in one area. They can endure multi-month missions, and their compact size makes deployment straightforward: a ten-strong constellation of C-Stars can be launched from a small fishing vessel. A sensor package is integrated into the platforms and can include passive acoustic sensors, infrared and visual cameras. Live information on meteorological and oceanographic conditions is relayed over satellite as often as once a minute. Instead of a single, expensive weather buoy, networks of these robots that are always “on”, can create wide-area sensing network to detect marine mammals, illegal fishing, and improve flood and hurricane forecasts. Oshen recently demonstrated the platform’s resilience firsthand, with a C-Star successfully traveling through a Category 5 hurricane in late September 2025.
