[Abstract]:With the wide application of industrial robots, as one of the performance indicators of industrial robots, the end position accuracy has gradually attracted people's attention. Due to the influence of various error factors, there are always some errors between the actual position and the theoretical position of the industrial robot, which seriously affects the application and popularization of the industrial robot in the case of high precision requirements. At present, calibration technology is the main method to improve the terminal position accuracy of industrial robots. In this paper, focusing on the calibration method and error compensation of six-degree-of-freedom industrial robot, taking a certain type of industrial robot as the object, the following work is carried out: aiming at the calibration problem of industrial robot, combined with the structural characteristics of industrial robot body, the kinematic model is established by DH (Denavit-Hartenberg) method, and the relationship between end position and DH parameters is derived. The kinematic model is verified by simulation and experiment. The conversion relationship between DH parameter error and end position error is derived, and the kinematic error model of industrial robot is further obtained. The linear correlation of kinematic parameters of industrial robot is analyzed, and the linear correlation parameters and their influence on the identification results of kinematic parameters are obtained. According to the kinematic model and error model, the least square method is proposed to solve the kinematic parameters of six-degree-of-freedom industrial robot. In order to simplify the steps of kinematic parameter identification, a genetic Tabu search algorithm is proposed in this paper, which does not need to analyze and transform the error model, but regards the parameter error solution as an optimization problem. The optimal value search is carried out by using the combination of genetic algorithm and Tabu search algorithm, and finally the optimal fitness function value is obtained. Based on the GUI interface between Robotics and MATLAB, the parameter identification software is compiled. The kinematic parameters of industrial robot are simulated and identified by using the least square method and genetic Tabu search algorithm, and the minimum amount of data required by the parameter identification algorithm is determined. The simulation results show that the absolute position accuracy of the end is improved obviously after parameter identification and compensation. After the parameter identification based on the least square method, the maximum direction error at the end of the robot decreases from 3mm to 0.005mm. After parameter identification based on genetic Tabu search algorithm, the maximum direction error at the end is reduced to 0.008mm. The joint arm coordinate measuring machine is used as the measuring tool to carry on the related experimental research. Firstly, the spatial position coordinates of the industrial robot end in the measuring machine coordinate system are measured, and then the spatial position coordinates are transformed into the industrial robot coordinate system by using the algorithm, and the kinematic parameters are identified by using the above two identification methods respectively. In general, the absolute position accuracy of the end of the robot is usually within 5mm. After identification, the maximum direction error decreases from 15mm to 0.7mm and 1.4mm, which can meet the requirements of the robot in general. Finally, the two groups of experimental results are compared and analyzed. The parameter identification effect based on least square method is better, but the identification step of parameter identification algorithm based on genetic Tabu search algorithm is simple, the efficiency is higher, and the algorithm can focus on the optimization of the algorithm.
