About

Yusuke Mitsui is a pioneering researcher in the field of underwater robotics, with a specialized focus on archaeological survey and excavation. His work addresses the critical challenge of exploring submerged cultural heritage sites, which are often located in hazardous, deep-water environments and obscured by sediment. Mitsui’s major contribution lies in the development of lightweight, remotely operated vehicles (ROVs) designed to perform delicate excavation work, a task traditionally limited to human divers. His most-cited paper, “Lightweight underwater robot developed for archaeological surveys and excavations” (2023, 16 citations), details a novel ROV that balances maneuverability with the power needed for underwater digging. This work builds on his earlier research, “Development of a Small Underwater Robot for Archaeological Survey in Fluctuating Water-Flow Environments” (2018, 4 citations), which validated robot performance in the challenging conditions of Lake Biwa, Japan—specifically at the Tsuzuraozaki underwater site at depths of 50–70 meters. By engineering robots that can operate in strong currents and perform precise tasks, Mitsui is enabling archaeologists to access and preserve underwater history that was previously unreachable, marking a significant leap forward in both marine technology and cultural heritage conservation.
