About
Keiichiro Shiraga is a robotics researcher specializing in acoustic positioning systems for GPS-denied environments, with a focus on agricultural and aerial applications. His work addresses the critical challenge of enabling precise navigation for robots and drones where satellite signals are unavailable. Shiraga’s major contributions include the development of the Spread Spectrum Sound-based Local Positioning System (SSSLPS), which leverages TDMA and FDMA techniques to achieve centimeter-level accuracy for multiple agricultural robots operating in greenhouses. His most cited paper (2022, 5 citations) demonstrates this system’s static and dynamic performance, highlighting its low cost and extensive coverage capabilities. In a subsequent study (2023, 3 citations), Shiraga advanced the field by proposing a Doppler shift compensation algorithm for dynamic UAVs, achieving a 90.2% detection rate and positioning errors as low as 75.9 ± 39.1 mm—meeting the stringent requirements for mobile aerial platforms. His research bridges the gap between acoustic localization and real-world deployment in challenging environments, offering a practical, scalable solution for precision agriculture and autonomous drone navigation. Shiraga’s work is foundational for future systems that demand reliable, high-accuracy positioning without GPS.
