About

Yeongil Park is a pioneering mechanical engineer whose work centers on the design and control of novel transmission systems and their integration into mobile robotics. His most significant contribution is the invention of the spherical continuously variable transmission (S-CVT), a groundbreaking mechanism that replaces traditional belt-driven CVTs with a sphere, input/output discs, and variators. This innovative design, detailed in his highly cited 2000 paper (53 citations), offers a more compact and efficient method for continuously varying torque and speed. Park extended this concept by applying the nonholonomic properties of the S-CVT to create a new class of wheeled mobile robots. His 2002 work (19 citations) demonstrates how this transmission can dramatically increase a robot’s operational run time by optimizing power transfer from the motor to the wheels. By merging theoretical kinematics with practical mechatronics, Park has provided a foundational platform for energy-efficient, long-duration autonomous vehicles, establishing himself as a key figure in the fields of nonholonomic systems and advanced transmission design.
