Markerless Vision-Guided Docking
This research presents a novel markerless, vision-based method for surgical robot localization using a RealSense 3D camera and a YOLO11 deep learning model. Unlike traditional methods requiring fiducials, this approach streamlines the surgical workflow by reducing additional hardware and procedural steps, enabling autonomous robot alignment with minimal human intervention. This translates to increased operational flexibility and reduced overhead in sterile environments.

Automated & Integrated Workflow
The study introduces a complete AI-to-PLC workflow, enabling real-time coordinate extraction, communication, and autonomous closed-loop motion. This integration significantly reduces the operator-dependent variability inherent in manual docking procedures, leading to improved consistency and reproducibility in surgical tasks. For enterprises, this means more predictable surgical schedules and optimized resource allocation.

Submillimeter Accuracy & Robustness
The framework achieves a submillimeter positioning accuracy (≤0.8 mm) and a significantly reduced alignment time (-42%) compared to manual methods. Extensive validation using an OptiTrack ground-truth system confirmed the robustness of the system under variable lighting conditions and camera angles, critical for real-world operating room environments. This level of precision and speed directly contributes to enhanced patient safety and surgical efficiency.

Integrated OR-Oriented System Architecture
The proposed system features an integrated OR-oriented architecture, designed for multi-patient operation, real-time responsiveness, and enhanced surgical safety. This includes robust error handling, safety constraints enforced by the PLC, and a design that minimizes additional hardware. This forward-thinking approach facilitates smoother integration into existing clinical environments and prepares for broader clinical validation.
Use Case: Automated Trocar Docking
In a simulated pancreatic surgical task, the ATHENA robot automatically positions its flange at the instrument site for easy and safe docking after the surgeon visually identifies the initial instrument position. This process utilizes real-time image analysis from the 3D stereoscopic camera, identifying the trocar, instrument, and robot's parallel module (PM). The system then computes 3D coordinates and guides the robot, with a trapezoidal velocity profile, to precisely align for instrument insertion.
Impact: Significantly reduces setup time and operator fatigue, while enhancing the precision of instrument insertion, crucial for delicate minimally invasive procedures.

Your AI Implementation Roadmap
A strategic phased approach for integrating advanced AI into your operations, ensuring seamless adoption and measurable results.
Phase 1: Discovery & Strategy (2-4 Weeks)
Initial on-site assessment in a hospital environment to verify compatibility with real operating-room workflow. Focus on practical aspects such as available space, sterility, draping requirements, and camera placement constraints. Refine mechanical design based on surgeon feedback.
Phase 2: Pilot & Development (8-12 Weeks)
Extend the dataset and validation protocol to explicitly include edge cases (e.g., severe lighting, occlusions, contamination) and quantify performance degradation. Implement conservative safety gating (confidence thresholds and temporal consistency checks) to prevent commands when visual uncertainty is high.
Phase 3: Integration & Scaling (12-20 Weeks)
Broader clinical validation with multi-site or multi-environment data acquisition and cross-domain evaluation. Enhance software reliability with fault handling, user interaction improvements, and sensor redundancy (e.g., multi-view RGB-D or complementary sensing) for edge cases. Prepare for full deployment.
