About

Kazuki Hirasawa is a pioneering researcher in the field of robotic olfaction, specializing in the development of aerial robots capable of detecting and tracking gas sources in three-dimensional space. His work centers on equipping multi-copter drones with semiconductor-type gas sensor arrays to locate hazardous chemicals and monitor environmental threats, such as forest fires. Hirasawa’s major contributions include the first experimental demonstrations of 3D odor plume tracking using drones, as shown in his 2015 paper (10 citations), and the advancement of 3D gas source localization in 2019 (11 citations). He has also explored bio-inspired approaches, such as Braitenberg’s vehicle-like odor tracking robots (2014, 6 citations), which simplify robotic navigation through direct sensor-actuator connections. With over 27 citations across his key works, Hirasawa’s research bridges robotics, sensor technology, and environmental monitoring, offering practical solutions for detecting chemical leaks and wildfires. His innovative use of quad-rotor platforms and sensor arrays has laid the groundwork for autonomous aerial systems that can safely and efficiently survey hazardous areas, making him a notable figure in the growing field of drone-based environmental sensing.
