About
Changho Lee is a mechanical and robotics engineer whose research spans deep-seabed mining systems and humanoid robotics. With a career built on solving complex engineering challenges in extreme environments, Lee has made notable contributions to the design and analysis of underwater mining infrastructure. His most cited work, a 2014 study on coupling device kinematics in deep-seabed mining systems (34 citations), investigated how a critical connector between buffer systems and flexible pipes influences the coordinated motion of entire mining assemblies — findings with direct implications for the safe and efficient extraction of manganese nodules from the ocean floor. Building on this, his 2015 research introduced a subsystem synthesis method to streamline the analysis of integrated deep-seabed mining systems, addressing the computational complexity of modeling vessels, lifting pipes, pumps, and self-propelled robots together. His 2014 multi-body dynamics study further refined the trajectory control of tracked mining robots navigating soft seabed terrain. Demonstrating versatile expertise, Lee also ventured into humanoid robotics, developing recursive inverse kinematics methods for depth-camera-based human motion teaching in 2020. His work collectively advances both resource extraction technology and intelligent robotic systems.
