Parallel robots are closed-loop mechanisms presenting very good performances in terms of
accuracy, velocity, rigidity and ability to manipulate large loads. They have been used in a …

This paper presents an overview of the literature on kinematic and calibration models of
parallel mechanisms, the influence of sensors in the mechanism accuracy and parallel …

Generating a defined motion is one of the fundamental tasks for a machine. By definition, a
robot is a universal machine dedicated to creating motion that can be freely programmed. A …

The paper deals with geometric calibration of industrial robots and focuses on reduction of
the measurement noise impact by means of proper selection of the manipulator …

The paper addresses a problem of robotic manipulator calibration in real industrial
environment. The main contributions are in the area of the elastostatic parameter …

Abstract Researchers have studied Stewart–Gough platforms, also known as Gough–
Stewart platforms or hexapod platforms extensively for their inherent fine control …

The robustness of robot calibration with respect to sensor noise is sensitive to the
manipulator poses used to collect measurement data. In this paper we propose an algorithm …

In this paper, a vision-based measuring device is proposed and experimentally
demonstrated to be an accurate, flexible, and low-cost tool for the kinematic calibration of …

Inaccuracy of the kinematic model used in robot controllers and deflection of robot joints are
two main sources of positioning errors in current industrial robots. We propose an elasto …

The accuracy problem is one of the most concerning problems for the industrial application
of a Stewart platform, and kinematic calibration is a feasible way to solve it. Although various …
