Composable Safety for Cooperative Robots

1 July, 2019

The CoR-Lab recently started a new EU-funded COVR AWARD project termed CoSMo focusing on composable safety models for cooperative and collaborative robot applications. The CoSMo project is lead by Dr.-Ing. Sebastian Wrede and carried out in collaboration with Fraunhofer IFF Magdeburg and Weidmüller Interface GmbH. The main target of this project is to enable system integrators to efficiently perform safety validations of potentially large numbers of cobot applications used in cooperative assembly processes. Nowadays, a cooperative robot workstation that facilitates a flexible arrangement of modular physical components must be individually certified upon each change of the setup and assembly process, which is in contrast with the required flexibility of agile manufacturing. 

In the CoSMo project, we will investigate whether the inherent modularity of the workstations can be lifted to the certification process. For this, three exemplary assembly processes will be investigated and set-up in a modular cobot workstation. Their safety requirements will be analyzed and a risk assessment will be carried out for each. Based on the concept of composable safety models, an extended validation process for modular workstations will be developed in interaction with the COVR experts and fed back to the toolkit, which shall ease the certification of modular Cobot applications.
