About

Won-Kyu Lee is a leading researcher in soft robotics, specializing in the development of electronics-free, pneumatic control systems that enable autonomous locomotion. His major contributions center on harnessing mechanical instabilities and fluidic logic to replace traditional electronic controllers. In his highly cited work "A soft ring oscillator" (214 citations), Lee pioneered a soft, pneumatic oscillator that generates coordinated periodic motion from a single constant-pressure source, eliminating the need for multiple separate components. He extended this concept in "A buckling-sheet ring oscillator for electronics-free, multimodal locomotion" (86 citations), demonstrating how soft oscillators can produce complex, gaited movements for robots without hard valves or computers. Lee’s research on "Elastic-instability–enabled locomotion" (25 citations) revealed a minimal principle for symmetry-breaking in motion, using a thin circular sheet that changes shape nonlinearly under pressure. Additionally, his work on "Tube-Balloon Logic" (22 citations) explores fluidic control elements that allow multiple actuators to be managed through soft digital logic gates. With over 347 total citations across these key papers, Lee’s innovations are foundational for creating simpler, more robust soft robots that can operate in environments where electronics are impractical.
