About

Dr. Hoseong Kwak is a leading roboticist whose research spans surgical robotics and humanoid locomotion, with a focus on creating more dexterous and intelligent machines. His most impactful work, "Surgical Robot for Single-Incision Laparoscopic Surgery" (53 citations), introduces a groundbreaking system featuring a cone-type remote center-of-motion mechanism and flexible, linkage-driven articulated instruments—a key innovation for minimally invasive procedures. In humanoid robotics, Dr. Kwak spearheaded the development of the Roboray platform, contributing to its lower-limb design (32 citations) and pioneering a torque-controlled balancing framework (16 citations) that leverages cable-driven, back-drivable joints for stable bipedal walking. His work on "Optimal Gait Primitives for Dynamic Bipedal Locomotion" (10 citations) further advanced the field by using numerical optimization to generate self-stable walking patterns. More recently, he has explored sensorless force control via momentum observers for robotic manipulators. With over 100 total citations, Dr. Kwak’s contributions are foundational to both surgical precision and dynamic robot locomotion, demonstrating a rare ability to bridge clinical application with fundamental biomechanical research.
