About
Shigeru Okuma’s research career is anchored in robotics and intelligent manufacturing, with a particular focus on ultrasonic sensing and automated assembly systems. His most cited work, “Distance measurement by an ultrasonic system based on a digital polarity correlator” (2001, 58 citations), addresses a critical challenge in mobile robotics: accurate two-dimensional position and orientation estimation within indoor environments. By developing a digital polarity correlator for pulse time-of-flight estimation, Okuma mitigated the echo confusion common in constant-frequency ultrasonic systems, offering a more reliable solution for robot navigation and localization. This contribution has been foundational for researchers working on sensor-based robotic perception. In parallel, Okuma explored the automation of disassembly tasks, as seen in his 2002 paper on using genetic algorithms to evaluate subassembly postures. This work tackled the geometric feasibility of robotic disassembly sequences, moving beyond purely translational constraints to consider complex spatial configurations. While less cited, it reflects his broader interest in optimizing manufacturing processes. Okuma’s impact lies in bridging practical sensor design with computational planning, providing tools that enhance both robotic autonomy and industrial efficiency.
