Lab FYP Project Recognized at ASMPT Technology Award 2026

We are pleased to announce that a final-year project developed by Bosco CHIM Ho Yin, under the supervision of Prof. Hongliang Ren, has received an Outstanding Award at the ASMPT Technology Award 2026.

🚀 From Seeing to Reasoning in Endoscopic Surgery 🤖👨‍⚕️

We are excited to share our latest Comment published in #npj Digital Medicine:
“How can reasoning capability empower the AI copilot robot in endoscopic surgery”

Current AI copilots in endoscopic surgery are still largely reactive and vision-driven. While they can detect anatomy, instruments, and scene changes, they often still struggle to truly understand surgical intent, infer hidden tissue dynamics, and respond robustly to uncertainty—all of which are essential for safe and precise intraoperative assistance.

In this article, we highlight how reasoning capability can become a key enabler for the next generation of AI copilot robots in endoscopic surgery:

  1. 🧠 Reasoning beyond perception: Enabling VLA-based surgical robots to go beyond simple visual recognition and translate high-level surgeon intent into precise, context-aware low-level motion goals.
  2. 🔄 Multimodal and uncertainty-aware intelligence: Fusing endoscopic vision with preoperative imaging, intraoperative sensing, and tracking signals, while dynamically re-weighting information sources under occlusion, bleeding, smoke, and other uncertain conditions.
  3. 🤝 Coordinated multi-instrument collaboration: Supporting synchronized control of multiple tools for subtasks such as traction, dissection, and hemostasis, with reasoning-guided adaptation to tissue deformation and workflow variation.
  4. 🔮 Anticipatory and safer decision-making: Using chain-of-thought-style reasoning to forecast tissue response, evaluate possible action outcomes, and generate more conservative and interpretable assistance under risk.
  5. 🏥 Surgeon-in-the-loop clinical deployment: Framing the AI copilot robot at LoA 2–3, where the system assists with task generation, monitoring, and bounded low-level execution under explicit safety constraints and continuous surgeon oversight.

We believe the future of endoscopic robotic assistance lies not only in systems that can see, but in systems that can reason, adapt, and collaborate. With reasoning-enabled VLA models, AI copilot robots may evolve from reactive executors into true cognitive partners in the operating room.

🚀 Advanced Science 2026: Transferable Autonomous Endoscopy Navigation! 🤖💊

Thrilled to share our latest Advanced Science work on enabling highly transferable, autonomous navigation for wireless capsule endoscopy (WCE)—using a lightweight Edge-Contour-Depth Fusion module and deep reinforcement learning (DRL).

WCE has revolutionized GI diagnostics, but its potential is often restricted by incomplete mucosal coverage and the poor ability of existing AI navigation methods to adapt across different patient anatomies. This motivated us to ditch the heavy, brittle, traditional “end-to-end” visual video streams that cause AI models to overfit to a single patient.

🧠✨ What we developed:
A unified, clinically viable framework that features:
🔹 Anatomical Landmark Guidance: Operates on stable, low-dimensional coordinates of conserved gastric structures (the fundus and pyloric antrum) rather than high-dimensional raw video.
🔹 Lightweight Perception Module: Combines classical Canny edge detection and Hu moments with a compact monocular depth network (DispNet) to run efficiently on low-power clinical hardware.
🔹 Robust Sim-to-Real Pipeline: Utilizes a patient-specific digital twin combined with a model-free Adaptive Dynamic Programming (ADP) controller to actively neutralize real-world physical disturbances and actuator latency.

🎯 Key Results:
✅ >97% mucosal coverage achieved within 50 seconds across 8 diverse, patient-derived stomach models in simulation.
✅ 87% mean coverage stability and a 53% reduction in procedure time during real-world ex-vivo experiments compared to expert manual control.
✅ Drastically reduced computational overhead, allowing deployment on low-cost processors (<2 TOPS).

💡 Why it matters:
This study establishes a scalable paradigm that conquers the “reality gap” and patient anatomical variability in medical robotics. By decoupling perception from control, it removes the need for expensive, massive patient datasets and high-end GPUs, paving the way for operator-independent, intelligent GI diagnostics.

🌱 What’s next?
We are expanding our training to encompass extreme pathological distortions (like hiatal hernias) and advancing toward fully wireless clinical deployment with dynamic, target-reaching capabilities for intraoperative pathologies.
