A Study of the Effect of a Kinematic Pair Containing Clearance on the Dynamic Characteristics of a Tool-Changing Robot

Wenxue Qian et al.

Summary: This paper investigates the influence of clearance in rotating motion pairs on the dynamic characteristics of a tool changing robot. A contact wear dynamics model is established based on a three-state model to analyze the impact of clearance size, rotational speed, and friction coefficient on the robot's dynamic characteristics. The results show that an increase in clearance size and actuating speed leads to a larger fluctuation range of velocity and acceleration, and a decrease in fluctuation frequency. Furthermore, friction reduces the contact force between components, thus improving the kinematic reliability of the mechanism.

Influence of Drift on Robot Repeatability and Its Compensation

Michal Vocetka et al.

Summary: This paper introduces an approach to reduce the repeatability difference of an industrial robot in cold and warm conditions by compensating for the effect of thermal expansion on its structure. By using highly accurate sensors and implementing a temperature-based prediction model, the methodology presented in this article successfully reduces the impact of thermal expansion on the robot's repeatability, with subsequent tests showing up to 89.9% reduction in drift. Robots upgraded with the compensation principle described in this article can maintain low repeatability errors across a wide range of temperatures without the need for preheating.

Examination and comparison of different methods to model closed loop kinematic chains using Lagrangian formulation with cut joint, clearance joint constraint and elastic joint approaches *

Filipe Marques et al.

Summary: This study presents several approaches to model and simulate closed loop topologies using the Lagrangian formulation, focusing on converting closed loop nature into open systems to simplify modeling. The methods considered include the cut joint approach, the clearance joint constraint model, and the elastic joint formulation, with a slider-crank mechanism used as a demonstrative example and comparison with the Newton-Euler method for constrained multibody systems.
