I am a Senior Researcher in Korea Institute of Industrial Technology. I'm interested in designing and controlling physically interacting robots. Especially, I have researched the energy-efficient compliant robot joint for physical human-robot interaction (p-HRI) during my Ph.D.
During my master's course, I focused on characterizing an ankle joint impedance to provide an accurate spasticity estimation. Similar to this technology, I studied human motor learning skills by estimating dynamic elbow joint stiffness during varying load conditions.
As an extension of my research background, I participated in developing numerous types of wearable assistive systems for my lab projects. First, I developed the surface EMG-based lower limb exoskeleton control algorithm. Second, I participated in designing and optimizing a fully-portable pneumatic-powered ankle-foot-orthosis (AFO) for drop-foot correction. Furthermore, I designed a pneumatic-powered lumbar support system.
For the underlying technology in robotic joints, I have experience in developing a high torque-density brushless DC motor. For the collaborative project with the company, I developed a haptic knob device with multiple resistance for exhibition in the Shinsegae department store in Daejeon.
In conclusion, I design and control robot systems, especially robot actuators for physically interacting applications.
