About

Jungyun Kim is a pioneering researcher in the field of mechanical engineering and robotics, with a specialized focus on continuously variable transmissions (CVTs) and their application to mobile robotics. His most significant contribution is the invention and development of the spherical continuously variable transmission (S-CVT), a novel mechanism that uses a sphere, input and output discs, and variators to achieve smooth, friction-based power transmission. Kim’s work demonstrates that the S-CVT allows motors to operate in their most power-efficient regime—high-speed and low-torque—dramatically improving the energy efficiency of mobile robots. His seminal 2000 paper on the S-CVT design has garnered 53 citations, laying the foundation for subsequent research. Building on this, Kim’s 2002 study on energy efficiency (31 citations) and his design of a nonholonomic S-CVT-based wheeled mobile robot (19 citations) show how the transmission can extend robot run times and enable smooth, continuous operation. His MOSTS robot (2003) further exemplifies the practical integration of the S-CVT into a mobile platform. With over 119 total citations across his key works, Kim’s innovations in nonholonomic CVT design and energy-optimized locomotion have made a lasting impact on the fields of transmission engineering and autonomous robotics.
