About

Wiha Choi is a researcher at the forefront of rehabilitation robotics and human-robot interaction, with a focus on developing compliant, safe, and effective robotic systems for human motion support and training. Her key research areas include series elastic actuators (SEAs), body weight support (BWS) systems, and robot-assisted exercise. Choi’s major contributions lie in designing and controlling robotic devices that enhance rehabilitation and physical training. Her most cited work, "Gravity and Impedance Compensation of Body Weight Support System Driven by Two Series Elastic Actuators" (2021, 19 citations), presents a novel approach to precisely controlling trunk support forces, improving safety and comfort for users during therapy. She also advanced the understanding of SEA performance under velocity control (2016, 9 citations), addressing critical challenges in compliant actuation. Additionally, her study on robot-resistance exercises (2019, 7 citations) provided valuable insights into how contraction type and speed affect muscle strength and activation, informing more effective training protocols. With a growing citation impact, Choi’s work is shaping the next generation of assistive and rehabilitative robotic technologies.
