About
Sam Hamner is a leading researcher in robot calibration and precision manipulation, with a primary focus on enhancing the positioning accuracy of industrial robotic arms. His most influential work, "Improved Positioning Accuracy of the PA10-6CE Robot with Geometric and Flexibility Calibration" (2008, 111 citations), introduced a groundbreaking 30-parameter flexible geometric model that dramatically reduced systematic errors in the Mitsubishi PA10-6CE robot. By applying this model, Hamner achieved a reduction in mean positional errors from 1.80 mm to sub-millimeter levels and peak errors from over 2 mm to less than 0.5 mm, demonstrating a fourfold improvement in accuracy. This work has become a cornerstone in the field of robot calibration, widely cited for its practical methodology and significant impact on manufacturing and automation. Hamner’s contributions have advanced the understanding of how geometric and flexibility parameters interact, enabling more precise and reliable robotic systems. His research continues to influence the development of high-accuracy robots for tasks ranging from assembly to surgical assistance, making him a key figure in modern robotics engineering.
