Nondestructive testing (NDT) is a comprehensive engineering application tech-nology using ultrasound, X-ray, electromagnetic wave, penetration and other physi-cal methods to nondestructively test and evaluate the internal discontinuity and material properties of mechanical components. It is also an important basis for evaluation of the integrity and service safety of mechanical components. It plays an important role in con-trolling and improving the manufacturing quality of mechanical products and ensuring the safe and reliable operation of in-service equipment, thus laying a foundation for the development of modern industry and high-end manufacturing equipment. It is hard for traditional NDT technology to realize the automatic detection of complex curved components, especially the automatic high-precision NDT of curved-surface com-ponents with variable curvature, variable thickness and complex contour, which, in most cases, rely on manual point-selection detection. Traditionally, a constant coupling distance between the detection transducer and the component under test, a stable and effective coupling state as well as flexible adjustment of spatial detection attitude is hard to achieve, resulting in the difficulty in ensuring the NDT precision. In contrast, robotic has been widely used in many industrial fields because of its good flexibility and wide adaptability. The technology of robotic NDT combines the physical principle of nondestructive testing with the flexible motion control of spatial attitude of articulated robotic. With NDT as the constraint, it controls the motion attitude and azimuth angle of a transmitting or receiving transducer. Thus, traditional NDT technique has developed from plane to curved surface, from 2D to many dimensions and from artificial testing to intelligent detection, into the interdisciplinary theory and technology of robotic NDT. Now the robotic NDT has been applied in aerospace, weapon, vehicle and other industrial fields.
