About

Gakuhito Hirasawa is a researcher specializing in robotic fabrication, digital manufacturing, and the preservation and modernization of traditional Japanese wooden architecture. His work sits at a distinctive intersection of heritage craft knowledge and advanced automation, exploring how articulated robotic systems can be harnessed to replicate and extend the complex joinery techniques characteristic of traditional Japanese timber construction. Hirasawa's most influential contribution, "Versatile Robotic Wood Processing Based on Analysis of Parts Processing of Japanese Traditional Wooden Buildings" (2018, 12 citations), established a foundational framework for automating the intricate cutting and shaping processes that define historical Japanese building systems. Complementing this, his earlier studies on tool path generation and parts processing using articulated robots addressed critical technical challenges, including automated tool selection and multi-axis path planning for geometrically complex components. More recently, Hirasawa has turned his attention to sustainable forestry concerns, developing database-driven robotic systems capable of transforming irregularly shaped thinned timber — typically considered waste material — into high-value architectural products. Collectively, his research demonstrates both technical ingenuity and a commitment to environmental sustainability, offering meaningful pathways for preserving traditional craftsmanship while addressing contemporary challenges in construction and forest resource management.
