Deliverable 2.1 Drill-LIBS

Deliverable D2.1 of the DISCOVER project (HORIZON-CL4-2023-TWIN-TRANSITION 01-11-101129909) details the development of the Pokey drilling robotic platform for material characterization in the built environment. The system integrates a robotic drilling platform with three sensing modalities: X-ray Fluorescence (XRF), Near-Infrared (NIR), and RGB imaging. It is designed to autonomously collect and analyze drill dust samples from 17 distinct classes of construction materials. XRF was chosen over the initially proposed LIBS for its superior stability, reproducibility, and easier robotic integration. The mechanical design features a modular frame, automated sample transport, and Hilti drilling components for robust operation. A LabVIEW-based control system manages the workflow, communicating with motor drivers and sensors. The collected multi-modal data is used to train and evaluate AI models for real-time, high-accuracy material classification.
