Materials Informatics (MI) demands high-throughput synthesis, thus it is highly needed an execution layer to translate MI-driven plans into physical action. We built this low-level orchestration layer using Robot Operating System 2 (ROS2), a flexible system that integrates and controls diverse lab equipment. It uses Python for high-level logic and C++ for timing-critical tasks, ensuring reproducibility. We demonstrated its effectiveness with 10 consecutive automated syntheses of the superconductor V₃Ge via arc melting. This yielded high-quality samples with sharp superconducting transitions (~6 K), validating the system's performance. The system is open-source on GitHub. Our talk will cover integrating other instruments, showcasing its broad applicability.
