+# 🧠 TTA-S2R: Pretrained YOLO Models Collection
+
+This repository contains the pretrained models used in the **TTA-S2R (Tidal Turbine Assembly – Sim2Real)** pipeline.  
+All models were trained and evaluated as part of the study on **sim-to-real transfer for industrial assembly object detection**.
+
+The collection includes YOLOv8, YOLOv9, and YOLO-World models trained under three regimes:
+- **Controlled only** – trained purely on real controlled data captured with a collaborative robot.
+- **Synthetic only** – trained purely on domain-randomized synthetic data.
+- **Synthetic + Controlled** – fine-tuned using both sources for improved sim-to-real generalization.
+
+---
+
+## 🧩 Usage
+
+You can load any model directly in Python using the [Ultralytics](https://github.com/ultralytics/ultralytics) framework:
+
+```python
+from ultralytics import YOLO, YOLOWorld
+
+# Example for YOLOv8 or YOLOv9
+model = YOLO("best_model_8_synthetic_controlled.pt")
+
+# Example for YOLO-World
+model = YOLOWorld("best_model_yoloworld_synthetic_controlled.pt")
+
+results = model.predict(source="path/to/image_or_video.jpg")
+
