Detection of Mechanical Play of Revolute Robot Joint

Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014
This article introduces a method of detection of mechanical play of revolute joint based on recognition of impacts caused by the play. The method uses inexpensive acceleration measuring device with limited sampling frequency. The impact is recognized indirecly according to oscillation of mechanical oscilator.

Kinematic Clearance Sensitivity Analysis of Spatial Structures With Revolute Joints (*)

Journal of Mechanical Design, 1999
The 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.

On the positioning of revolute‐joint robot manipulators

Journal of Robotic Systems, 2000
Summary: We develop a new technique for obtaining the sets of joint-motor-displacements which correspond to a desired spatial pose at the end-effector of a revolute-joint manipulator. The properties of rotation are exploited, and a local coordinate notation is introduced to obtain the required solution. We obtain two simplified sets of linear equations

Multi-objective Optimization of Mechanisms with Clearances in Revolute Joints

2014
Despite extensive work on the evaluation of the dynamic performances of various mechanisms and multi-body mechanical systems with revolute joint clearances, limited work has been conducted in optimizing the performances of these systems. A multi-objective optimization technique is presented to examine and to quantify the effect of combined objective ...
