Abstract
This study presents a digital twin (DT)-enabled framework for robotic non-destructive evaluation (NDE) of surface cracks in civil infrastructure, integrating real-time data acquisition, immersive visualization, and remote inspection. The framework consists of a robotic platform equipped with a laser surface profiler (LSP) for high-resolution 3D surface scanning, a structured database for crack-related data storage, a game engine for virtual reality (VR) visualization, and a VR interface supporting user interactions through a headset and controllers. As a case study, the Federal Highway Administration (FHWA)’s Virtual NDE Laboratory (VLab) is used to evaluate the system. The LSP, mounted on a robotic arm, captures detailed 3D surface profiles of cracks, which are visualized in the VR environment. Users can interact with multi-dimensional crack data in real time, executing inspection commands for remote analysis. The results demonstrate the fusion of surface data with immersive visualization, providing an interactive and scalable approach for surface crack inspection. By integrating robotic automation, real-time visualization, and digital twins, this framework enhances efficiency, accuracy, and objectivity in surface crack detection and assessment.
