About

Takumi Yasui is a robotics researcher specializing in bio-inspired inspection systems for critical infrastructure. His primary research areas include peristaltic motion robotics, pipeline inspection, and 3D mapping using embedded sensors. Yasui’s most significant contribution is the development of an earthworm-inspired robot equipped with a camera and IMU sensor, designed to navigate narrow, aging sewer pipes. His 2019 paper on three-dimensional mapping from inside pipelines (11 citations) proposes a novel method to generate 3D maps of pipe interiors, addressing the urgent need to detect leaks and structural failures before they cause road damage. In his 2020 work (9 citations), he advanced pipeline-shape measurement by leveraging the robot’s peristaltic motion for highly accurate length measurement, solving the common problem of lost pipeline diagrams. Yasui also tackled the practical challenge of navigating bent pipes, developing a specialized joint attachment (5 citations) to ensure reliable passage through curved sections. His work directly impacts public safety and infrastructure maintenance, offering cost-effective, autonomous solutions for inspecting hard-to-reach underground systems.
