•  In collaboration with WHOI NDSF and DeepSea Challenger, develop a technologically advanced 11k HROV (ROV or AUV) for R/V Falkor, supporting: –  Robust access to abyssal and hadal zones for scientific research

–  UHD / 3DHD / panoramic HD video acquisition and streaming

–  Scientific data collection (seafloor mapping, chemical and thermal data collection, photomosaicing, etc.)

–  Versatile scientific sample collection

–  Object manipulation (e.g. collection and deployment of equipment)

•  HROV will satisfy SOI operational requirements –  HROV will be optimized for operation on R/V Falkor

–  HROV will support single body launch and recovery
