Abstract

This paper builds a kinematic model for the end-effector positioning error of manipulator with account of joint clearance and then presents a probabilistic approach for evaluating the error characteristics. This probabilistic approach, in which the Monte Carlo simulation is applied, can not only obtain the maximum deviation of the positioning error but also get the error distribution and its numerical features. Then comprehensive approach coupled with the deterministic way and the probability way is proposed to give a better consideration for both the main influence factors and other uncertain items. Case study illustrates the probability evaluation method. The work will provide a new approach for industrial robot design, which takes the accuracy and manufacturing cost into account.
