Software-defined architectures are at the forefront of sophisticated industrial applications. The Software-Defined Vehicle has revolutionised the automotive industry, allowing the evolution of system after manufacture. Robotics as an industry can benefit tremendously from this concept as applications can evolve post-deployment with software updates over the air and other network links to remote software-deployment services. This concept is not without its challenges, as software must skew towards scalable architectures to support a dynamic codebase. This research demonstrates the capability of creating reusable and composable software abstract from specific hardware architectures. Our approach lays the foundation of scalable software architectures devoid of hardware requirements, creating the possibility for reusable, embedded software entities and key aspects of automation. We first demonstrate infrastructure that decouples the hardware specification from the needs of software interfacing with it. We show how to create scalable software integrating multiple hardware architectures, including microcontrollers and FPGAs. We show that such a software architecture can integrate seamlessly with CI/CD pipelines, promoting continuous hardware-in-the-loop testing and integration.
