In the worlds of nuclear energy, mining, petrochemical processing, and sub-sea, robots are being used for an increasing number and range of tasks. This is resulting in ever more complex robotics installations being deployed, maintained, and extended over long periods of time. Additionally, the unstructured, experimental, or unknown operational conditions frequently result in new or changing system requirements, meaning extension and adaptation is necessary. Whilst existing frameworks allow for robust integration of complex robotic systems, they are not compatible with highly efficient maintenance and extension in the face of changing requirements and obsolescence issues over decades-long periods. We present ongoing activities at RACE that attempt to solve the long-term maintainability and extensibility issues encountered in such scenarios through the use of a standardised, self-describing data representations and associated communications protocols. Progress in developing and testing software frameworks to implement this, as well as an overview of current and planned deployments, will be presented.
