About

Dr. Yunliang is a leading figure in precision robotics, specializing in the enhancement of industrial robot accuracy for high-stakes manufacturing tasks. His core research focuses on advanced metrology and error compensation, where he has pioneered the development of the 3-D Passive Scale Tracker (3DPST). This innovative instrument provides a low-cost, high-accuracy solution for measuring and correcting the complex motion errors inherent in industrial robots. In his most cited work (2024, 5 citations), Dr. Yunliang introduced a nonlinear optimization approach for precisely identifying geometric errors within the 3DPST itself, establishing a new standard for self-calibration in robotic measurement systems. He further demonstrated the practical impact of this technology by integrating the 3DPST with an Epson robot to create a drilling system that actively compensates for real-time positioning and orientation errors (2024, 2 citations). By bridging the gap between theoretical error modeling and industrial application, Dr. Yunliang’s contributions are pivotal for advancing the precision of robotic machining, assembly, and automation in fields requiring micron-level accuracy.
