About

Hee-Hwan Park is a robotics researcher whose work focuses on advancing industrial automation, particularly in the areas of inverse kinematics and portable robotic systems for manufacturing. His most notable contribution is an iterative algorithm for solving the inverse kinematics of 5-degree-of-freedom manipulators with offset wrists, a challenging problem in robotics due to the limited orientation capabilities of such systems. This algorithm, published in 2012, minimizes iteration count to efficiently compute solutions where only the tool’s z-direction is constrained—a critical advancement for tasks like welding and assembly. The work has garnered 7 citations, reflecting its relevance to kinematic optimization. Park also made a significant impact with the development of a portable welding robot designed for shipbuilding yards. This 6-DOF, 3 kg payload robot weighs just 21.5 kg, enabling human workers to carry it to worksites. Constructed primarily from lightweight magnesium and aluminum alloys, it features an EtherCAT interface for high-speed communication. With 4 citations, this 2011 paper demonstrates Park’s commitment to practical, deployable automation solutions that enhance productivity in heavy industries. His research bridges theoretical kinematics and real-world robotic applications, making him a notable figure in industrial robotics.
