ArthroCut: Autonomous Policy Learning for Robotic Bone Resection in Knee Arthroplasty

ICRA 2026poster

Despite rapid commercialization of surgical robots, their autonomy and real-time decision-making remain limited in practice. To address this gap, we propose ArthroCut, an autonomous policy learning framework that upgrades knee arthroplasty robots from assistive execution to context-aware action gene…

Endoscopic Spine Surgical View Enhancement Via Diffusion-Prior Contrastive and Physics-Informed Constraints for Robotic Navigation

ICRA 2026poster

In robot-assisted spinal endoscopy, intraoperative imaging is frequently degraded by bleeding, irrigation fluids, bubbles, smoke, and uneven illumination, which can severely compromise surgical precision, safety, and decisionmaking. Accurate identification of anatomical structures is particularly cr…

Hysteresis-Aware Neural Network Modeling and Whole-Body Reinforcement Learning Control of Soft Robots

ICRA 2026poster

Soft robots are inherently compliant and safe, making them suitable for humaninteractive applications such as surgery. However, their nonlinear and hysteretic behavior poses significant challenges for accurate modeling and control. We present a soft robotic system and propose a hysteresis-aware whol…

Hysteresis-Aware Neural Network Modeling and Whole-Body Reinforcement Learning Control of Soft Robots

RA-L 2025

Soft robots are inherently compliant and safe, making them suitable for human-interactive applications such as surgery. However, their nonlinear and hysteretic behavior, arising from the properties of soft materials, presents substantial challenges for accurate modeling and control. In this study, w

A Novel Robotic Bronchoscope with a Spring-Based Extensible Segment for Improving Steering Ability

ICRA 2024poster

Bronchoscopy, as an essential minimally invasive diagnostic and therapeutic modality, assumes a pivotal role in the early detection of lung cancer. However, the complex anatomy of the airway and the fixed length of the bronchoscope’s bending segment, along with its external propulsion property, pose…

Revisiting Score Propagation in Graph Out-of-Distribution Detection

NeurIPS 2024poster

The field of graph learning has been substantially advanced by the development of deep learning models, in particular graph neural networks. However, one salient yet largely under-explored challenge is detecting Out-of-Distribution (OOD) nodes on graphs. Prevailing OOD detection techniques developed…
