About

Roberto Hideaki Tsunaki is a researcher whose work lies at the intersection of precision metrology and industrial robotics, with a primary focus on developing automated, dedicated systems for geometric error measurement. His most significant contributions center on using industrial robots as flexible, automated measuring platforms for evaluating the form errors of mechanical components—particularly straightness and profile inspection. In his seminal 2008 work, "Robot measuring form errors" (13 citations), and his highly cited 2007 paper on straightness evaluation (11 citations), Tsunaki pioneered the integration of multi-probe error separation techniques to decouple measurement results from the robot's inherent coordinate system inaccuracies. This innovation was critical for achieving the high precision required in industrial quality control. His 2005 work on robot-based dedicated measuring systems with data redundancy further advanced the field by addressing how to mitigate systematic measurement errors in repetitive inspection tasks. Tsunaki has also explored the application of mathematical morphology in object tracking for position-based visual servoing, demonstrating a broader interest in vision-guided robotic control. Through his focused body of work, Tsunaki has made foundational contributions to the development of cost-effective, automated, and highly accurate robotic inspection systems for manufacturing.
