About

Dr. Dae-Hyeong Ji is a robotics engineer specializing in underwater vehicle navigation and robotic manipulator design for inspection and rescue operations. His research focuses on developing robust control systems for unmanned underwater tracked vehicles (UTVs), where he addresses the critical challenge of accurate navigation without a Doppler velocity log (DVL). In his most cited work (2019, 7 citations), Ji introduced a novel navigation algorithm integrating ultrashort baseline and ring laser gyro sensors, enabling reliable underwater positioning and control. This contribution is particularly valuable for operations in shallow or cluttered underwater environments where traditional DVL-based systems may fail. Ji has also made notable contributions to field robotics through the kinematic and dynamic analysis of robot arms designed for hazardous environments (2016, 4 citations). His work on a Pitch-Pitch-Pitch-Yaw manipulator configuration optimizes camera stability for inspection tasks, while a separate Yaw-Pitch design supports rescue operations. By combining theoretical analysis with practical sensor integration, Ji’s research advances the capabilities of autonomous systems operating in challenging, unstructured environments.
