Professor Noboru Noguchi's research lab specializes in the development of autonomous robotic systems for agricultural applications, focusing on precision navigation, sensor fusion, and intelligent work scheduling. The lab pioneers the integration of RTK-GPS, inertial measurement units (IMU), and fiber optic gyroscopes (FOG) to enable high-accuracy, real-time guidance of field robots in complex environments. Research also extends to unmanned surface vehicles (USVs) for paddy field operations and optimization algorithms for electric spraying robots in challenging terrains such as mountainous orchards. The lab emphasizes practical implementation of automation technologies to enhance agricultural efficiency and sustainability.

The objective of the study was to develop a field robot in agricultural operation environment.The navigation sensor consisted of an RTK-GPS and an inertial measurement unit (IMU). Thesensor fusion algorithm was capable of identifying FOG bias and compensating location error inreal-time for providing sufficient navigation information in support of accurate robot guidance inthe field. The field tests of a field robot have been conducted in Sapporo, Japan. Tillage,planting, cultivating and splaying
This study developed a field robot for an agricultural operating environment. Thenavigation sensor consisted of an RTK-GPS, a fiber optic gyroscope (FOG), and an inertialmeasurement unit (IMU). A sensor fusion algorithm was used to identify FOG bias andcompensate for location error in real-time, thus providing sufficient navigation information tosupport accurate robot guidance in the field. The guidance system could guide the agriculturalrobot automatically to follow either straight or curve pat
With the intensive application of techniques in global positioning, machine vision, image processing, sensor integration, and computing-based algorithms, vehicle automation is one of the most pragmatic branches of precision agriculture, and has evolved from a concept to be in existence worldwide. This paper addresses the application of robot vehicles in agriculture using new technologies.
