摘要
常规的轨迹跟踪误差自动化校正,主要采用分析干扰变量进行误差校正,忽略了柔性关节姿态角对约束参量的影响,导致误差校正值结果较小.因此,提出工业机器人柔性关节轨迹跟踪误差自动化校正研究.建立工业机器人运动学模型,通过工业机器人柔性关节的仰俯角和横滚角综合计算姿态角,进而得出柔性关节的约束参量,计算校正系数完成连续性的轨迹跟踪自动化校正.实验结果表明:所提方法应用后得出的误差校正值结果较大,均值为 0.2 rad,校正效果较优,满足工业机器人的现实应用需求.
Abstract
The conventional automated correction of trajectory tracking errors mainly relies on analyzing interference variables for error correction,ignoring the influence of flexible joint atti-tude angles on constraint parameters,resulting in smaller error correction values.Therefore,a method of automated correction of trajectory tracking errors in flexible joints of industrial robots is proposed.A kinematic model of an industrial robot is established,and the attitude angle is ob-tained by comprehensively calculating the pitch angle and roll angle of the flexible joints of the in-dustrial robot;on this basis,the constraint parameters of the flexible joints are obtained and the correction coefficient is calculated to complete continuous automated correction of trajectory tracking.The experimental results show that the error correction values obtained by the proposed method after application are relatively large,with a mean of 0.2 rad.The correction effect is ex-cellent and meets the practical application needs of industrial robots.
