About
Sanguk Choi is a rising leader in the field of wearable robotics, with a focused expertise in the design and control of series elastic actuators (SEAs) for human-robot interaction. His work centers on developing compact, cable-driven systems that enhance the performance of soft wearable robots, particularly for ankle and hip assistance. Choi’s major contributions include the creation of the Flexi-SEA, a flexible-shaft-driven actuator that reduces mechanical inertia for distal joint support, and a precise torque-output estimation method for reaction-force-sensing SEAs, critical for safe human-robot interaction. His research also advances real-world applicability through a walking-speed-adaptive gait phase estimation module, enabling continuous, monotonic phase tracking across varying speeds. With over 36 citations across his most-cited papers, Choi’s impact is evident in both technical innovation and clinical validation, as demonstrated by a randomized crossover trial showing the efficacy of his soft wearable robot for hip assistance in chronic stroke patients. His work bridges the gap between actuator design and practical rehabilitation, marking him as a key contributor to next-generation assistive technologies.
