Leveraging the CHINGMU optical motion capture system, the Institute of Intelligent Control for Complex Electromechanical Systems at Kunming University of Science and Technology conducted a systematic research program on robotic arm calibration. By capturing high-fidelity kinematic trajectory data across each joint of the robotic arm and integrating this data stream directly with the arm's control system, the research team achieved significant improvements in positional accuracy calibration and motion trajectory algorithm optimization efficiency — providing robust ground-truth data support and methodological validation for intelligent robotic arm control.
