SSTL: Self-Sensing Tendon Loop for Hysteresis Modeling and Compensation in Tendon-Sheath Mechanisms
Myeongbo Park, Junhyun Park, Ihsan Ullah +2
Flexible endoscopic robots enable minimally invasive access through natural orifices, but their control accuracy is limited by configuration-dependent hysteresis in the tendon-shea…
Markerless 6D Pose Estimation and Position-Based Visual Servoing for Endoscopic Continuum Manipulators
Junhyun Park, Chunggil An, Myeongbo Park +3
Continuum manipulators in flexible endoscopic surgical systems offer high dexterity for minimally invasive procedures; however, accurate pose estimation and closed-loop control rem…
SIMS: Surgeon-Intention-driven Motion Scaling for Efficient and Precise Teleoperation
Jeonghyeon Yoon, Sanghyeok Park, Hyojae Park +3
Telerobotic surgery often relies on a fixed motion scaling factor (MSF) to map the surgeon's hand motions to robotic instruments, but this introduces a trade-off between precision…
Vibration-Assisted Hysteresis Mitigation for Achieving High Compensation Efficiency
Myeongbo Park, Chunggil An, Junhyun Park +2
Tendon-sheath mechanisms (TSMs) are widely used in minimally invasive surgical (MIS) applications, but their inherent hysteresis-caused by friction, backlash, and tendon elongation…
OFF-CLIP: Improving Normal Detection Confidence in Radiology CLIP with Simple Off-Diagonal Term Auto-Adjustment
Junhyun Park, Chanyu Moon, Donghwan Lee +2
Contrastive Language-Image Pre-Training (CLIP) has enabled zero-shot classification in radiology, reducing reliance on manual annotations. However, conventional contrastive learnin…
