About

Hiroyuki Hatta is a pioneering researcher in agricultural robotics, with a focused expertise in the development of autonomous weeding robots for wet rice cultivation. His primary contributions lie in creating robotic systems that can navigate paddy fields without chemical herbicides, addressing the growing demand for pesticide-free and environmentally sustainable farming. Hatta’s most impactful work, "Effect for a Paddy Weeding Robot in Wet Rice Culture" (2018, 43 citations), demonstrates the practical viability of autonomous weeding, while his earlier studies—such as "Development of Weeding Robot for Paddy Field" (2013) and "Weeding Robot Control for Rice Plant Line Following" (2015)—established foundational methods for robot navigation and soil adaptation. A notable achievement is his innovative use of capacitive touch sensors to detect rice plant lines, enabling precise, non-destructive weeding. Hatta also developed turning algorithms for autonomous operation in tight paddy spaces. Though his citation counts are modest, his work is highly specialized and directly applicable to sustainable agriculture, making him a key figure in the niche field of precision weeding robotics.
