The accuracy and precision of OMC technology need to be assessed in order to ensure safe human\u2013robot interactions, but the accuracy specifications provided by manufacturers are easily influenced by various factors affecting the measurements. This article describes a new methodology for the metrological evaluation of a human\u2013robot collaborative environment based on optical motion capture (OMC) systems. Inspired by the ASTM E3064 test guide, and taking advantage of an existing industrial robot in the production cell, the system is evaluated for mean error, error spread, and repeatability. A detailed statistical study of the error distribution across the capture area is carried out, supported by a Mann\u2013Whitney U-test for median comparisons. Based on the results, optimal capture areas for the use of the capture system are suggested. The results of the proposed method show that the metrological characteristics obtained are compatible and comparable in quality to other methods that do not require the intervention of an industrial robot.<\/jats:p>","DOI":"10.3390\/s21113748","type":"journal-article","created":{"date-parts":[[2021,5,31]],"date-time":"2021-05-31T03:45:29Z","timestamp":1622432729000},"page":"3748","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Metrological Evaluation of Human\u2013Robot Collaborative Environments Based on Optical Motion Capture Systems"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1605-7998","authenticated-orcid":false,"given":"Leticia","family":"Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Multisensor Systems and Robotics Group (SiMuR), Department of Electrical, Electronic, Computer and Systems Engineering, University of Oviedo, C\/Pedro Puig Adam, 33203 Gijo\u0301n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8910-4855","authenticated-orcid":false,"given":"Juan C.","family":"\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Multisensor Systems and Robotics Group (SiMuR), Department of Electrical, Electronic, Computer and Systems Engineering, University of Oviedo, C\/Pedro Puig Adam, 33203 Gijo\u0301n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5589-6954","authenticated-orcid":false,"given":"Antonio M.","family":"L\u00f3pez","sequence":"additional","affiliation":[{"name":"Multisensor Systems and Robotics Group (SiMuR), Department of Electrical, Electronic, Computer and Systems Engineering, University of Oviedo, C\/Pedro Puig Adam, 33203 Gijo\u0301n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0395-2712","authenticated-orcid":false,"given":"Diego","family":"\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Multisensor Systems and Robotics Group (SiMuR), Department of Electrical, Electronic, Computer and Systems Engineering, University of Oviedo, C\/Pedro Puig Adam, 33203 Gijo\u0301n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102022","DOI":"10.1016\/j.rcim.2020.102022","article-title":"Safety assurance mechanisms of collaborative robotic systems in manufacturing","volume":"67","author":"Bi","year":"2021","journal-title":"Robot.
