Assessment of the positioning performance of an industrial robot
Purpose – The purpose of this work is to investigate the use of a laser tracker, a laser interferometer system and a telescopic ballbar for assessing the positioning performance of a six-axis industrial serial robot. The paper also aims to illustrate the limitations of these three metrology instruments for the assessment of robot positioning performance and to demonstrate the inadequacy of simp...
متن کاملImprovement of Gaofen-3 Absolute Positioning Accuracy Based on Cross-Calibration
The Chinese Gaofen-3 (GF-3) mission was launched in August 2016, equipped with a full polarimetric synthetic aperture radar (SAR) sensor in the C-band, with a resolution of up to 1 m. The absolute positioning accuracy of GF-3 is of great importance, and in-orbit geometric calibration is a key technology for improving absolute positioning accuracy. Conventional geometric calibration is used to a...
متن کاملAn improvement of the BeppoSAX LECS and MECS positioning accuracy
We present a study of the source positioning accuracy of the LECS and MECS instruments on-board BeppoSAX. From the analysis of a sample of archival images we find that a systematic error, which depends on the spacecraft roll angle and has an amplitude of ∼ 17” for the LECS and ∼ 27” for the MECS, affects the sky coordinates derived from both instruments. The error is due to a residual misalignm...
متن کاملAchieving Fine Absolute Positioning Accuracy in Large Powerful Manipulators
Important robotic tasks could be most effectively done by powerful and accurate manipulators. However, high accuracy is generally unattainable in manipulators capable of producing high task forces due to such factors as high joint, actuator, and transmission friction and link elastic and geometric distortions. A method called Base Sensor Control (BSC) has been developed to compensate for nonlin...
متن کاملCalibration of Robot Reference Frames for Enhanced Robot Positioning Accuracy
Industrial robot manipulators are important components of most automated manufacturing systems. Their design and applications rely on modeling, analyzing, and programming the robot tool-center-point (TCP) positions with the best accuracy. Industrial practice shows that creating accurate robot TCP positions for robot applications such as welding, material handling, and inspection is a critical t...
