“…Der "Contact Models Estimator" verbindet CARA mit Kollisionsprüfständen, um ein Kollisionsmodell für verschiedene Roboter mit Endeffektoren in unterschiedlichen Anwendungsfällen nach der in [7] definierten Methodik zu approximieren. Die Kontaktmodelle können dann in CARA integriert und automatisch verwendet werden, um physikalische Werte in Anwendungsfällen mit ähnlichen Robotererreichbarkeitsszenarien zu quantifizieren.…”

Das Engineering-Tool CARA (Computer-Aided Risk Assessment) des Fraunhofer-Instituts für Produktionstechnik und Automatisierung IPA erleichtert die Einführung von Anwendungen mit Mensch-Roboter-Kollaboration in der Industrie, indem es die Risikobeurteilung vereinfacht und teilweise automatisiert. Laut Entwicklungspartner DENSO Corporation konnte der technische Aufwand für die Risikoanalyse und Risikominderung durch CARA um mehr als 55 % reduziert werden.

“…His overview of influencing factors cites velocity, mass, design of the tool, singularities, collision monitoring, body regions, and the identification of hazard points [ 22 ]. Recently other studies using biofidel measuring devices to validate the safety of collaborative robot applications were found as well [ 23 , 24 , 25 ].…”

Biofidel measuring devices are used to validate safety in collaborative workplaces. In these workplaces, humans work together with robots that are equipped with a Power and Force Limiting function (PFL). In this experimental comparison, differences between devices and possible causes are examined more closely. Safety-related parameters are identified in a literature review. Focusing on mechanical aspects, three biofidel measuring devices are analysed and compared in an experimental test series. To this end, a linear motor and a pendulum are used and the steps for comparing concepts are proposed and applied. Depending on the stiffness settings and the materials used, geometry effects on the force-deformation behaviour are shown. An oscillation occurred in one case. The comparison of the three devices shows average differences of 5% in measured peak force between them. This study helps to achieve uniform and comparable results in practice.
