About

Ruoyi Hao is a rising researcher in surgical robotics, with a focus on flexible endoscopic systems and stiffness-tunable mechanisms for minimally invasive procedures. Their work addresses critical challenges in robot-assisted gastrointestinal endoscopic surgery (GES) and natural orifice transluminal endoscopic surgery (NOTES), aiming to enhance dexterity, autonomy, and safety in confined anatomical spaces. Hao’s most impactful contribution, “Modeling and Compensation of Stiffness-Dependent Hysteresis for Stiffness-Tunable Tendon-Sheath Mechanism in Flexible Endoscopic Robots” (2023), has garnered 25 citations, introducing a novel framework to mitigate hysteresis in stiffness-tunable miniature manipulators—a persistent barrier to precise control. Their development of the GESRsim simulator (2022, 7 citations) provides a foundational platform for advancing autonomous capabilities in gastrointestinal surgical robots. More recently, Hao’s work on a variable-stiffness nasotracheal intubation robot with passive buffering (2025, 4 citations) demonstrates translational impact through mannequin studies, highlighting modular design for emergency airway management. By integrating modeling, simulation, and hardware innovation, Hao is shaping the next generation of intelligent, adaptable surgical tools for complex endoscopic procedures.
