About

Fuju Lee is a leading expert in sensor calibration and inertial navigation systems, with a particular focus on triaxial accelerometer and magnetometer technologies. His groundbreaking work has fundamentally advanced the precision and reliability of motion-sensing devices used in robotics, aerospace, and autonomous systems. Lee’s most influential contribution, "Calibrating a triaxial accelerometer-magnetometer - using robotic actuation for sensor reorientation during data collection" (2005), has garnered 47 citations and introduced a novel kinematic model and maneuver executed on a six-degrees-of-freedom robotic arm. This method enabled highly accurate calibration by reorienting sensors during data collection, with rigorous experimental validation through simulation analysis. In a complementary study, "Optimization-based calibration of a triaxial accelerometer-magnetometer" (2005, 7 citations), Lee further refined the process by estimating sensitivity, bias, and inter-axis angles for each sensor component using optimization techniques. Together, these works have set a new standard for sensor calibration, reducing errors in orientation tracking and magnetic field measurement. Lee’s achievements are widely recognized in the fields of robotics and mechatronics, and his methodologies continue to influence modern sensor fusion and autonomous navigation systems.
