About

Osamu Tsukamoto is a robotics researcher whose work centers on the automation of mold polishing, a critical and labor-intensive step in manufacturing. His primary research areas include force-controlled robotics, fuzzy control systems, and the generation of tool-path data from computer-aided manufacturing (CAM) systems. Tsukamoto’s major contribution lies in developing techniques to transform standard 3-axis cutter location (CL) data into normalized tool vectors that simultaneously define both the desired translational trajectory and the force direction for a polishing robot. This innovation allows for precise, automated polishing of complex surfaces, such as those found in PET bottle molds. To achieve this, he pioneered an open-architecture hybrid control method that weakly couples position and force feedback loops, enabling the robot to maintain consistent contact pressure while following a curved path. Though his most-cited papers, including "The Polishing Robot for PET Bottle Molds Using a Fuzzy Force Controller" (5 citations), represent foundational work in a niche but industrially significant field, Tsukamoto’s research directly addresses the practical challenge of replacing manual polishing with reliable, automated systems, making him a notable contributor to the advancement of intelligent manufacturing and robotic finishing processes.
