Explosion-Proof Paint Cobot Inspection Pipeline with OpenCV and Fanuc Telemetry

Hazardous paint booth environments require precise cobot path execution combined with real-time visual paint quality inspection. You will create an automated inspection and motion control pipeline using OpenCV and PyTorch to analyze paint thickness uniformity and detect surface drips from Fanuc CRX-10iA/L painting cobots. The vision pipeline must detect paint flaws larger than 0.5mm with 95% precision.
