About

Hanjun Yeom is a leading researcher in the field of energy-efficient robotics, with a particular focus on continuously variable transmission (CVT) systems for mobile platforms. His most-cited work, "On the energy efficiency of CVT-based mobile robots" (2002, 31 citations), provides a foundational analysis of how spherical-type CVTs (S-CVTs) can dramatically improve robotic energy performance. Yeom demonstrated that by decoupling motor speed from wheel speed, the S-CVT allows electric motors to operate in their most efficient regime—high-speed, low-torque—while enabling smooth, continuous motion without the efficiency losses of traditional gearboxes. This contribution is critical for extending battery life and operational range in autonomous mobile robots. Yeom’s research bridges mechanical design and control systems, offering practical solutions for sustainable robotics. His work has been cited in studies on planetary rovers, service robots, and electric vehicle drivetrains, underscoring its interdisciplinary impact. For students and researchers, Yeom’s insights into CVT-based energy optimization remain a cornerstone for designing next-generation, power-efficient autonomous systems.
