About

Eiichi Morioka is a leading researcher in robotics and automation, with a primary focus on developing innovative inspection systems for heavy civil engineering machinery. His most notable contribution is the creation of WInBot, a disc cutter wear inspection robot designed for tunnel boring machines (TBMs). This work addresses a critical challenge in tunneling: the need to safely and efficiently measure wear on disc cutters during excavation. Morioka’s robot features a high-expansion-ratio actuator that enables operation in the extremely confined spaces inside a TBM, and he proposed two novel wear measurement methods to enhance accuracy. Although his highly specialized work has garnered 3 citations to date, its practical significance is substantial—WInBot represents a pioneering step toward automating hazardous maintenance tasks, reducing downtime, and improving worker safety in underground construction. His research bridges the gap between advanced robotics and real-world infrastructure needs, demonstrating how tailored automation can solve long-standing industrial problems. Morioka’s contributions are particularly valuable for researchers and engineers working on field robotics, inspection systems, and the mechanization of tunnel engineering.
