Accuracy Analysis of Parallel Manipulators With Joint Clearance
Journal of Mechanical Design, 2008Due to joint clearance, a parallel manipulator’s end-effector exhibits position and orientation (or collectively referred to as pose) errors of various degrees. This paper aims to provide a systematic study of the error analysis problem for a general parallel manipulator influenced by joint clearance.

Analysis and experimental study of the spherical joint clearance
SPIE Proceedings, 2013The spherical joint clearance is a key error factor, which influenced and restricted the application of parallel mechanism in high precision field. This paper discusses the regularity of the spherical joint clearance in the parallel mechanism and its influence on the accuracy of the parallel mechanism in both theoretical and experimental aspects.

Minimal Deviation Paths for Manipulators With Joint Clearances
Volume 5B: 38th Mechanisms and Robotics Conference, 2014Manipulator joint clearance is a natural consequence of manufacturing processes. Although most studies in the literature have assumed zero joint clearance, its existence is unavoidable and thus its impact needs to be evaluated. With the miniaturizing trend in engineering products, errors due to joint clearance have become an increasingly important ...

Kinematic Clearance Sensitivity Analysis of Spatial Structures With Revolute Joints (*)
Journal of Mechanical Design, 1999The paper presents a new method to assess the influence of joint clearances in spatial structures that are composed of links connected by revolute joints. The method allows assessment of the amount by which joint clearances affect the rigid-body position of a generic link of the structure when an external load is exerted on the link.
