A Fuzzy Approach for the Kinematic Reliability Assessment of Robotic Manipulators

Fabian A. Lara-Molina et al.

Summary: This paper develops a novel method to assess the kinematic reliability of robotic manipulators based on fuzzy theory, evaluating the effect of joint clearances on end-effector position and computing a failure possibility index. Compared with traditional methods, this new assessment provides a fresh perspective on kinematic performance, with numerical results compared to a probabilistic approach based on Monte Carlo simulation.

A Calibration Method for Enhancing Robot Accuracy Through Integration of Kinematic Model and Spatial Interpolation Algorithm

Junde Qi et al.

Summary: Industrial robots are gradually finding their niche in the field of machining due to their advantages of high flexibility, good versatility, and low cost. However, challenges remain in high-precision machining processes due to limitations in absolute positioning accuracy. This study proposes a compensation method that takes into account the source and characteristics of positioning errors to improve accuracy.
