About

Kazuhiko Arai is a pioneering figure in construction robotics, with a career dedicated to automating the most physically demanding tasks on building sites. His primary research areas include the development of mobile robots for concrete finishing and automated systems for exterior wall painting. Arai’s most notable contribution is the "Mark II" mobile robot for concrete floor slab finishing (1988), a landmark project that demonstrated the practical feasibility of using autonomous machines for heavy construction work, earning 10 citations. He further advanced the field with the development of an exterior wall painting robot capable of navigating walls with indentations and protrusions (1993, 7 citations), solving a key challenge in façade automation. Arai also contributed foundational work on the systematic analysis of construction tasks for robotization (1990), providing a methodological framework for identifying which jobs are best suited for automation. His research, presented at the International Symposium on Automation and Robotics in Construction (ISARC), has influenced subsequent generations of construction robots, proving that even the most rugged, unstructured environments can be transformed by intelligent machines.
