About

Marco Ulrich is a leading researcher in the field of high-precision robot-based inspection systems, focusing on the intersection of industrial robotics and optical metrology. His work addresses a critical challenge: standard industrial robots offer speed and flexibility but suffer from poor absolute positioning accuracy, making them unsuitable for quality control tasks. Ulrich’s major contribution lies in developing innovative, calibration-free methods to overcome this limitation. His most cited paper (14 citations) introduces an automated, cycle-time-optimized path planning algorithm for robot-guided 3D sensors, directly enhancing inspection throughput. He further advanced the field by pioneering a high-accuracy 3D image stitching technique that corrects for robot inaccuracies without the need for external tracking or kinematic calibration—a significant practical advantage. Ulrich has also systematically analyzed the non-geometric effects (e.g., joint compliance, thermal drift) that degrade robot pose accuracy, providing a foundational understanding for future calibration models. With a cumulative citation count of 30 across his core works, Ulrich’s research is instrumental in enabling cost-effective, in-line quality inspection for modern production lines.
