About

Kiyoshi Tsuru is a leading figure in the development of wall-climbing robotics, with a primary focus on magnetic adhesion and high-mobility systems for industrial inspection and maintenance. His most significant contribution is the "Anchor Climber," a swarm-type wall-climbing robot that uniquely combines high payload capacity with superior mobility—a long-standing challenge in the field. This work, his most cited paper (18 citations), proposes a system capable of carrying heavy tools while navigating vertical surfaces. Tsuru further advanced the field with the "Window Cleaning Robot with Magnetic Synchronous Drive" (13 citations), a lightweight design using paired indoor/outdoor magnetic units for safe, actuator-efficient cleaning. He also pioneered the Internally-balanced Magnetic Unit (IB Magnet), a fundamental technique that cancels internal magnetic forces to allow easy detachment and reattachment, crucial for practical deployment. His development of the Vmax III robot (4 citations) achieved holonomic and omni-directional mobility on ferromagnetic walls, enhancing manipulation capabilities for complex tasks on large structures like gas tanks and reactor walls. Through these innovations, Tsuru has directly addressed the critical issues of uneven-surface adaptation and payload-mobility trade-offs, laying essential groundwork for autonomous robots that can replace humans in dangerous high-altitude work.
