About

Uhn Joo Na is a robotics engineer and researcher whose work sits at the intersection of haptic systems, teleoperation, and intelligent robot control. His most significant contribution is the development of a novel 6-DOF parallel haptic device designed for the precise teleoperation of serial robots — a system engineered to meet demanding requirements including low inertia, rapid motion response, large orientation angles, and high applied torques. This work, his most cited publication with 75 citations, represents a meaningful advance in human-robot interaction technology. Na's research extends into challenging operational environments, notably underwater robotics, where he developed acoustic transducer-based remote control systems capable of overcoming the severe signal attenuation limitations that render conventional radio and optical communication ineffective. His interests also encompass intelligent control, including the application of adaptive neuro-fuzzy controllers to compensate for nonlinear friction and disturbance effects in robot manipulators — a persistent challenge in achieving precise robotic motion. Across his body of work, Na demonstrates a consistent focus on bridging theoretical kinematics with practical engineering solutions, making him a notable contributor to applied robotics research for students exploring teleoperation and parallel mechanism design.
