Available in PDF, EPUB and Kindle. Book excerpt: The industrial robots are widely employed in various industries. Normally, the industrial robots are highly repeatable. However, their accuracy is relatively poor. If the robot’s end-effector is required to move to a pre-calculated pose (as in off-line programming), its position error may reach a couple of millimeters. To meet the growing demand for high absolute accuracy in robotic applications such as deburring, polishing, drilling, and fastening, a lot of research work has been carried out. Robot calibration is normally used to enhance the accuracy by using external pose measurement sensors such as laser tracker. However, the calibration procedure is long and the cost is high. Also, the accuracy enhancement is limited and the best reported accuracy is around ±0.1mm. In addition, the changing operating environment and the wear and tear of the robot affect the accuracy. This research aims at developing a novel and cost-effective dynamic pose correction (DPC) strategy to address the above-mentioned issues on the accuracy enhancement. This strategy uses the vision system, i.e. C-Track from Creaform Inc. to measure the pose and integrates with the robotic controller, also known as visual servoing. To realize this strategy, three main research activities have been conducted. First, the pose of the robot is obtained from the binocular sensor. The triangulation method for estimating the pose of an object is elaborated and the C-Track as a binocular sensor is introduced. In order to remove the noise from the C-Track’s measurements, the analysis on the measured data is carried out. A root mean square (RMS) method is used to achieve reliable pose estimation. Next, the DPC strategy is designed and simulated for an industrial robot, Fanuc M20-iA. This strategy can correct the position and orientation of the robot end-effector by using position-based visual servoing. A proportional-integral-derivative (PID) controller is proposed to achieve the dynamic pose correction. The algorithm does not need the kinematic and dynamic model of the robot. The controller is fully tested in Matlab/Simulink with robotic toolbox where Fanuc M20-iA is simulated. The simulation results validated the effectiveness of the proposed DPC. The final research work is dedicated to the experimental testing of the proposed DPC on Fanuc M20-iA. The pose estimated from the C-Track serves as the feedback and the output of the DPC is given to the robot controller through Fanuc dynamic path modification (DPM) function. As a result, the robot is guided to the desired pose in real time. The experimental results demonstrate that the robot can achieve the position accuracy ±0.05mm and orientation accuracy ±0.05 degree.

Book Synopsis Camera-Aided Robot Calibration by : Hangi Zhuang
Download or read book Camera-Aided Robot Calibration written by Hangi Zhuang and published by CRC Press. This book was released on 2018-04-24 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Robot calibration is the process of enhancing the accuracy of a robot by modifying its control software. This book provides a comprehensive treatment of the theory and implementation of robot calibration using computer vision technology. It is the only book to cover the entire process of vision-based robot calibration, including kinematic modeling, camera calibration, pose measurement, error parameter identification, and compensation. The book starts with an overview of available techniques for robot calibration, with an emphasis on vision-based techniques. It then describes various robot-camera systems. Since cameras are used as major measuring devices, camera calibration techniques are reviewed. Camera-Aided Robot Calibration studies the properties of kinematic modeling techniques that are suitable for robot calibration. It summarizes the well-known Denavit-Hartenberg (D-H) modeling convention and indicates the drawbacks of the D-H model for robot calibration. The book develops the Complete and Parametrically Continuous (CPC) model and the modified CPC model, that overcome the D-H model singularities. The error models based on these robot kinematic modeling conventions are presented. No other book available addresses the important, practical issue of hand/eye calibration. This book summarizes current research developments and demonstrates the pros and cons of various approaches in this area. The book discusses in detail the final stage of robot calibration - accuracy compensation - using the identified kinematic error parameters. It offers accuracy compensation algorithms, including the intuitive task-point redefinition and inverse-Jacobian algorithms and more advanced algorithms based on optimal control theory, which are particularly attractive for highly redundant manipulators. Camera-Aided Robot Calibration defines performance indices that are designed for off-line, optimal selection of measurement configurations. It then describes three approaches: closed-form, gradient-based, and statistical optimization. The included case study presents experimental results that were obtained by calibrating common industrial robots. Different stages of operation are detailed, illustrating the applicability of the suggested techniques for robot calibration. Appendices provide readers with preliminary materials for easier comprehension of the subject matter. Camera-Aided Robot Calibration is a must-have reference for researchers and practicing engineers-the only one with all the information!

Book Synopsis Singularity-Based Calibration - A Novel Approach for Absolute-Accuracy Enhancement of Parallel Robots by : Philipp Last
Download or read book Singularity-Based Calibration - A Novel Approach for Absolute-Accuracy Enhancement of Parallel Robots written by Philipp Last and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time a robot calibration approach has been presented that does exclusively rely on the information delivered by the robot-system itself. Hence, as neither additional sensors nor special constraint devices are required in order to apply parameter identification methods, the proposed technique is very economical and easy to use. It is thus especially convenient to be used in small and medium sized companies which do neither own special robot calibration equipment nor have professional skilled robot calibration experts. The basic idea of the new calibration scheme has been explained from a theoretical point of view by means of a simple example structure and subsequently validated through experiments by means of a more complex spatial parallel structure. The obtained results emphasize the promising potential of the approach.

Book Synopsis Two-dimensional Pose Estimation of Industrial Robotic Arms in Highly Dynamic Collaborative Environments by : Thomas Gulde

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modern collaborative production environments where industrial robots and humans are supposed to work hand in hand, it is mandatory to observe the robot's workspace at all times. Such observation is even more crucial when the robot's main position is also dynamic e.g. because the system is mounted on a movable platform. As current solutions like physically secured areas in which a robot can perform actions potentially dangerous for humans, become unfeasible in such scenarios, novel, more dynamic, and situation aware safety solutions need to be developed and deployed. This thesis mainly contributes to the bigger picture of such a collaborative scenario by presenting a data-driven convolutional neural network-based approach to estimate the two-dimensional kinematic-chain configuration of industrial robot-arms within raw camera images. This thesis also provides the information needed to generate and organize the mandatory data basis and presents frameworks that were used to realize all involved subsystems. The robot-arm's extracted kinematic-chain can also be used to estimate the extrinsic camera parameters relative to the robot's three-dimensional origin. Further a tracking system, based on a two-dimensional kinematic chain descriptor is presented to allow for an accumulation of a proper movement history which enables the prediction of future target positions within the given image plane. The combination of the extracted robot's pose with a simultaneous human pose estimation system delivers a consistent data flow that can be used in higher-level applications. This thesis also provides a detailed evaluation of all involved subsystems and provides a broad overview of their particular performance, based on novel generated, semi automatically annotated, real datasets.
