Embodiment Construction
[0053] In this embodiment, a cable-driven parallel robot kinematic parameter error calibration method based on position and attitude measurement is applied to the calibration process of the cable-driven parallel robot, and a position and attitude measurement device is installed on the side of the cable-driven parallel robot; specifically In other words, the error calibration method includes: a parallel robot kinematics parameter error identification model, a position and attitude measurement device coordinate system calibration module, and a robot kinematics parameter error identification module.
[0054] There are kinematic parameter errors in the cable-driven parallel robot, and the kinematic parameter error model of the parallel robot is established according to the kinematic model of the parallel robot; the parameter error identification model is obtained according to the kinematic error parameter model and the error measured by the position and attitude measurement device, ...
