About
Dr. Yitian Xian is pioneering the next generation of robotic surgical systems, with a focus on semi-autonomous and autonomous endoscopy for minimally invasive procedures. Their research spans colonoscopy, laparoscopy, and neurosurgery, where they have developed novel continuum mechanisms—including a DNA-inspired reinforced double helix—and electromagnetically actuated soft-tethered colonoscopes. A key contribution is the integration of visual servo control and binocular camera-based tracking to enable autonomous instrument following, reducing the cognitive load on surgeons. Their work on a semi-autonomous stereotactic brain biopsy robotic system, enhanced with safety-critical control barrier functions, addresses the pressing challenges of surgical safety and surgeon-robot collaboration. With over 80 citations across their most-cited papers, Dr. Xian’s impact is evident in advancing robotic autonomy from mechanical guidance to task-level execution. Notable achievements include the design of an active flexible endoscope holder for solo laparoscopic surgery and model-based bending control for automatic retroflexion in confined spaces. Their research is shaping a future where robots not only assist but intelligently collaborate with surgeons, improving precision and patient outcomes.
