SUNFISH is a user-friendly and person-portable Autonomous Underwater Vehicle (AUV) with field proven Artificial Intelligence (AI) and Simultaneous Localization and Mapping (SLAM). SUNFISH was developed by Stone Aerospace in collaboration with NASA for future exploratory mission to the Jovian moon, Europa. The AUV was designed to explore an ocean hidden beneath more than 15 km of ice and autonomously gather data from the alien planet. SUNFISH addresses many challenges of autonomous exploration in complex environments. The AUV is designed to operate in a wide variety of undersea environments, ranging from man-made (e.g. piers or harbors) to natural (e.g. reefs or caves).SUNFISH is able to carry out exceedingly difficult, precision underwater tasks. It accelerates exploration and asset inspection through rapid delivery of high quality imagery and 3D maps. During operations SUNFISH can report back, allowing a surface-based team to review, and re-task the vehicle. It can stop in mid flight, hover, and perform proximity operations along objects it has mapped and do so at specified stand-off ranges while acquiring high resolution photos and geometry. This precision, combined with sophisticated artificial intelligence, makes SUNFISH ideal for complex and combined environments.
