About
Yoon Su Baek is a prominent robotics engineer whose research has profoundly shaped the field of wearable assistive technology, with a particular focus on lower limb exoskeleton systems for individuals with mobility impairments. His work spans the mechanical design, actuation, sensing, and intelligent control of rehabilitation robotics, addressing the complex biomechanical challenges of replicating natural human movement. Baek's most influential contribution — a knee exoskeleton leveraging foot pressure and knee torque sensors (95 citations) — demonstrated how polycentric four-bar linkage mechanisms could faithfully replicate the anatomical motion of the human knee. His early work on paraplegic lower limb exoskeletons (58 citations) pioneered the application of Centre of Pressure (CoP) measurement to exoskeleton control, a technique previously underutilized in the field. He has further advanced actuation technology through electro-hydraulic systems and bidirectional tendon-driven actuators, combining high load capacity with energy efficiency. His integration of fuzzy logic algorithms and PID neural networks into motion profiling reflects a commitment to intelligent, intent-driven control. With over 340 cumulative citations across his most recognized works, Baek's research has made meaningful strides in making assistive exoskeletons lighter, smarter, and more biomechanically faithful — offering genuine promise for clinical rehabilitation applications.
