R3-COP (Resilient Reasoning Robotic Co-operating Systems) aims at providing European industry with new leading-edge innovation that will enable the production of advanced robust and safe cognitive, reasoning autonomous and co-operative robotic systems at reduced cost. The major objective is to achieve cross-sector reusability of building blocks, collected in a knowledge base, by developing and implementing a generic framework and platform with domainspecific instantiation, and use of a multi-purpose computing platform. The R3-COP Framework is targeting at a European RTP for robust autonomous systems embodying methodologies, methods, and tools for safety-critical hard-real-time system development and verification supported by European tool vendors. To enable this, interoperability issues have to be resolved at several levels, including meta-models, models, tool interfaces and component descriptions. The link is established by the knowledge base described in more detail in this short paper to allow composing of robotic applications from building blocks, and guiding design & development as well as validation & verification (supporting certification in the end). Co-operation with other projects of the ARTEMIS High-Rel cluster is envisaged, especially CESAR, MBAT and SafeCer (design, testing, certification), which is facilitated by partners very strongly involved in several of these projects. The concept of the knowledge base could be re-used contributing to the CRTP (Common Reference Technology Platform).
