Estimation of uncertainty of laser interferometer measurement in industrial robot accuracy tests

  title={Estimation of uncertainty of laser interferometer measurement in industrial robot accuracy tests},
  author={Jerzy J{\'o}zwik and Elżbieta Jacniacka and Dawid Ostrowski},
The subject of this article is the assessment of measurement uncertainty of the Renishaw XL80 laser interferometer in MOTOMAN HP20 industrial robot inaccuracy test. The paper presents the methodology for estimating the measurement uncertainty of the system used in tests. Estimates of standard and extended uncertainty were calculated for the given research method. These uncertainties are based on the information included in the device calibration certificate (method B) but also on the basis of… Expand
