About

Dr. Sarah Robinson Webster is a leading figure in marine robotics, with a primary focus on the design and deployment of hybrid autonomous underwater vehicles (AUVs) for deep-sea exploration. Her most influential work, "The *Nereus* hybrid underwater robotic vehicle" (2009), has garnered 49 citations and represents a landmark achievement in ocean engineering. This paper details the development of *Nereus*, a revolutionary vehicle capable of operating both as a free-swimming AUV for broad-area mapping and as a tethered remotely operated vehicle (ROV) for precise sampling at depths exceeding 11,000 meters—reaching the deepest ocean trenches. Webster’s contributions directly addressed the critical challenge of enabling versatile, deep-ocean research without the need for multiple specialized platforms. Her work has profoundly impacted the field, providing scientists with a powerful tool for studying hadal zone ecosystems and geological processes. By bridging the gap between autonomous and tethered systems, Webster’s research has not only advanced robotic capabilities but also expanded the frontiers of deep-sea science, inspiring a new generation of engineers to push the boundaries of underwater technology.
