About

Albert Nubiola is a robotics researcher whose work has fundamentally advanced the field of industrial robot calibration and accuracy improvement. His research centers on geometric and kinematic calibration methods, metrology-based performance assessment, and error modeling for six-axis serial robots — areas where his contributions have proven both practically valuable and widely influential. Nubiola's most celebrated work, "Absolute calibration of an ABB IRB 1600 robot using a laser tracker" (2012), has accumulated an remarkable 576 citations, establishing him as a leading authority on robot accuracy enhancement. Alongside this, his development of single-telescoping ballbar calibration methods offered a more accessible alternative to expensive laser tracker systems, earning 178 citations and demonstrating his commitment to practical, cost-effective solutions. His comparative studies of calibration approaches — employing optical CMMs, laser trackers, and interferometers — gave the robotics community rigorous benchmarks for choosing appropriate metrology tools. Beyond calibration, Nubiola made notable contributions to understanding backlash error, servo system contouring errors, and observability-based calibration efficiency. His 30-parameter kinematic and compliance models significantly improved robot positioning accuracy. With over 1,200 cumulative citations, his body of work remains an essential reference for researchers and engineers striving to bridge the gap between theoretical robot models and real-world performance.
