The convergence of robotic arms, edge computing, and 5G non-public networks has opened new avenues for industrial automation. This paper presents a technically evolved demonstrator, based on the HYDRA concept, which embodies a novel approach to revolutionize industrial automation through collaborative and coordinated operations among multiple robotic arms. The HYDRA concept leverages the power of robotic arms working in close proximity, enabled by a two-layer architecture comprising a HYDRA core in a Multi-Access Edge Computing (MEC) environment and multiple HYDRA satellites connected via a non-public 5G network. This paper outlines the architecture, implementation, and impact of the HYDRA concept on industry.
