    An Improved Data-Driven Calibration Method with High Efficiency for a 6-DOF Hybrid Robot by Zhibiao Yan, Youyu Wang, Haitao Liu, Juliang Xiao, Tian Huang

    Published 2022-12-01
    “…Then, a large number of robot poses can be acquired in the whole workspace via a limited number of measurements, effectively solving the curse of dimensionality in measurement. (2) A mapping between the nominal joint variables and joint compensation values is established using a back propagation neural network (BPNN), which is trained directly using the measurement data through a unique algorithm involving inverse kinematics. …”
