About

Masaki Nakagawa’s research lies at the intersection of wireless communications, mobile robotics, and haptic feedback systems, with a focus on enabling reliable, real-time remote control. His most significant contribution is the development of the “cellular ad-hoc united communication system,” a hybrid architecture where mobile terminals intelligently switch between direct ad-hoc links and base station connections based on communication conditions. This work, first proposed in 1996 and examined in his most-cited paper (22 citations), addresses a critical challenge for operational mobile robots operating in dynamic or shadowed environments. Nakagawa further demonstrated the system’s effectiveness under shadowing (9 citations), showing how adaptive mode selection maintains connectivity where traditional cellular networks fail. He also pioneered investigations into the impact of wireless transmission errors on haptic information (5 citations), a crucial step toward safe remote surgery and hazardous material handling. Additionally, his work on OFDM subcarrier selection (3 citations) tackled the low-latency requirements of real-time haptic and video feedback. Though his citation counts are modest, Nakagawa’s contributions are foundational to the emerging field of networked telerobotics, directly influencing how robots can be controlled wirelessly in mission-critical, human-support applications.
