About

Yudai Yamada is a robotics researcher specializing in the design and development of novel mobile robots for challenging industrial environments. His primary research areas include ceiling mobile robots and inspection robots for tunnel boring machines. Yamada’s most significant contribution is the creation of the "HanGrawler" series of ceiling mobile robots. The original HanGrawler (2020, 30 citations) introduced a crawler-based system that hangs from perforated metal ceiling plates, enabling high-speed, large-payload transport with freely selectable routes—a breakthrough for automating material handling in production sites. He advanced this work with "HanGrawler 2" (2021), which achieved speeds of 1 m/s and 90°/s, matching ground carriers. Additionally, Yamada developed "WInBot" (2019), a disc cutter wear inspection robot for tunnel boring machines, featuring a high-expansion-ratio actuator to operate in narrow spaces. His work bridges the gap between theoretical robotics and practical industrial automation, with his HanGrawler platform demonstrating particular promise for transforming overhead logistics. Yamada’s research is characterized by a focus on mechanical innovation to solve real-world constraints, making him a notable figure in field robotics and industrial automation.
