  We examine a simple scheme to generate genuine multipartite entangled states
across disjoint qubit registers. We employ a shuttle qubit that is sequentially
coupled, in an energy preserving manner, to the constituents within each
register through rounds of interactions. We establish that stable $W$-type
entanglement can be generated among all qubits within the registers.
Furthermore, we find that the entanglement is sensitive to how the shuttle is
treated, showing that a significantly larger degree is achieved by performing
projective measurements on it. Finally, we assess the resilience of this
entanglement generation protocol to several types of noise and imperfections,
showing that it is remarkably robust.
