About

Tetsuya Kodama is a pioneering researcher whose work bridges the gap between advanced ultrasonic sensing and human-robot interaction. His foundational contributions to ultrasonic distance measurement systems have significantly enhanced the precision and reliability of mobile robot localization. Kodama’s most influential paper, “Distance measurement by an ultrasonic system based on a digital polarity correlator” (2001, 58 citations), introduced a novel method for pulse time-of-flight estimation that mitigates signal confusion, a critical advancement for indoor robot navigation. Building on this, his 2005 work on digital polarity correlators (40 citations) applied pulse compression techniques from radar engineering to sonar ranging, effectively reducing crosstalk and external interference in multi-user environments. More recently, Kodama has ventured into the innovative field of behavior modification through his concept of “TSUNDERE Interaction” (2021), which integrates cold (TSUN) and kind (DERE) actions to reinforce desired behaviors using operant conditioning with user-favorite avatars. This creative fusion of robotics, acoustics, and psychology demonstrates his versatility and forward-thinking approach. With a career spanning foundational sensor technology to cutting-edge human-machine interaction, Kodama’s work continues to inspire new directions in both engineering and interactive design.
