About

Haruka Ueda is a pioneering figure in underwater robotics, with a career-long focus on developing hydraulic actuation systems that operate directly in seawater. Her most-cited work, the 1991 paper "Seawater hydraulic actuator system for underwater manipulator," introduced a groundbreaking approach to subsea robot design. By creating a system that uses seawater as the working fluid—rather than traditional oil-based hydraulics—Ueda enabled the miniaturization of underwater manipulators while eliminating the need for complex seals and pressure compensation systems. This innovation, which has accumulated 33 citations, laid the foundation for more efficient, compact, and reliable deep-sea robotic tools. Ueda’s contributions are particularly notable for their practical impact on offshore exploration, underwater construction, and marine science, where her actuator designs have improved the dexterity and endurance of remotely operated vehicles. Her work remains a touchstone for researchers in fluid power and marine robotics, demonstrating how rethinking fundamental engineering principles can unlock new capabilities in extreme environments.
