基于距离误差的服务机器人运动学参数标定研究
Research on kinematic calibration of service robot based on distance error
摘要
Abstract
A single joint error model of service robot has been set up independently ,which is based on MDH ( Modified Denavit-Hartenberg) model,the distance between two points in space to measure the error absolute positioning accuracy of the robot ,and combined with the establishment of a single joint error model ,the kinematic calibration model based on distance error was de-duced.The kinematics calibration model not only can simplify the measurement process ,but also avoids coordinate conversion be-tween measurement system and robot system ,and improves measurement accuracy.Finally,combined with the decoupling of the service robot structure characteristics to select the scheme of the experimental measurement points , and use three coordinates measuring instrument measuring the terminal position.Experimental results show that the precision of the robot has been increased by more than 60%.关键词
