About

Sang-Bum Lee is a robotics engineer specializing in industrial automation, particularly for shipbuilding and heavy manufacturing environments. His key research areas include portable robotic systems, welding automation, and real-time control interfaces. Lee’s most notable contribution is the development of a portable welding robot with an EtherCAT interface, designed to address the unique challenges of shipyard welding. This six-degree-of-freedom robot, weighing only 21.5 kg and constructed primarily from lightweight magnesium and aluminum alloys, can be carried by human workers to remote work sites. With a 3 kg payload capacity, it enables precise welding in confined or hard-to-reach spaces where traditional stationary robots cannot operate. Although his most-cited paper has garnered 4 citations, its practical impact is significant: it represents a shift toward human-portable, flexible automation in heavy industry. Lee’s work bridges the gap between conventional industrial robotics and the need for mobile, adaptable tools, offering a solution that improves both safety and efficiency in shipbuilding. His research continues to influence the design of lightweight, high-performance robotic systems for demanding industrial applications.
