About

Katsutoshi Ootsubo is a robotics researcher whose work centers on teleoperation systems for construction robots, with a particular focus on enhancing safety and operability in hazardous environments such as disaster recovery sites. His research addresses the critical challenge of enabling remote operation of heavy construction machinery — specifically hydraulic excavators — in dangerous conditions where direct human presence poses significant risk. Ootsubo's most notable contributions include the development of master-slave teleoperation frameworks that provide operators with realistic environmental presence, and innovative support systems for slope shaping tasks essential to sediment disaster prevention and recovery. A recurring theme across his work is improving operator precision and reducing mental workload; his 2018 study introduced drone-based visual support systems to address these challenges, representing a meaningful integration of unmanned aerial vehicles with ground-based construction robotics. His earlier work explored augmented reality (AR) presentation methods to enrich the operator's situational awareness during remote task execution. With his most-cited papers each accumulating 9 citations, Ootsubo's research has established a foundational body of work in construction tele-robotics. His contributions are particularly relevant to researchers and engineers exploring human-robot interfaces, disaster response automation, and the practical deployment of remotely operated heavy machinery in real-world emergency scenarios.
