About

Tetsuo Hagiwara is a pioneering robotics researcher whose work focuses on extending the physical and functional limits of robotic manipulators for hazardous environments. His key research areas include long-reach modular manipulators, novel actuator design, and intuitive human-robot interfaces. Hagiwara’s most impactful contribution is the development of the **Hiryu-II**, a long-reach articulated modular manipulator driven by thrusters for weight compensation (2020, 8 citations). This work addresses a fundamental challenge in robotics: enabling manipulators to exceed traditional length limits through refined hardware design, opening new possibilities for disaster response and industrial inspection. Earlier, he developed the **X-screw** (2000, 3 citations), a load-sensitive continuously variable transmission that functions as a linear actuator, offering unique advantages for robotic applications requiring adaptive force control. Hagiwara also contributed to human-robot interaction with the **Armrest Joystick** (2012, 4 citations), designed to simplify control of manipulators in dangerous settings like disaster sites and minefields. His career reflects a consistent focus on pushing mechanical boundaries—whether through actuator innovation or extended reach—making his work foundational for next-generation robots operating in extreme environments.
