摘要

It is often the case that a robot must adapt to unexpected changes in its environment. It is, however, important that these changes can be demonstrated to maintain the safe operation of the robot. The adaptive systems community has developed the MAPE-K pattern as a widely recognised conceptual architecture. We propose extending MAPE-K to incorporate runtime verification, resulting in an architecture we call MAPLE-K. In this paper, we capture and formalise both the MAPE-K and MAPLE-K architectures using a domain-specific language. Additionally, we provide support for translation from architectural models to software models and code to facilitate the deployment of verified applications. MAPE-K is rarely maintained at the implementation level, but our work ensures traceability between the code and its design, enabling the use of architectural information to verify the correctness of the software.
