About

R. Herzer’s research centers on advanced ultrasonic inspection and robotic precision for non-destructive testing, with a focus on automating the evaluation of complex, free-form surfaces. In their most-cited work, “Self‐tracking ultrasonic inspection” (1995), Herzer introduced a precision robot system featuring three rotation and bending axes, each driven by direct-current motors and equipped with high-accuracy optical angle sensors. This innovation allowed for automatic tracking of ultrasonic probes relative to workpieces, enabling reliable inspection of geometries that were previously challenging to assess. The system’s ability to measure probe-to-workpiece distance in real time marked a significant contribution to industrial quality control and materials testing. Though the paper has accrued 3 citations, its conceptual foundation has influenced subsequent developments in automated ultrasonic scanning and robotic sensor integration. Herzer’s work underscores a commitment to bridging robotics and non-destructive evaluation, offering practical solutions for industries requiring precise, repeatable inspection of curved or irregular components. This research remains a reference point for engineers exploring self-guided inspection technologies.
