Your description sounds similar to the plot of the first novel of what would become the Galactic Center Series by Gregory Benford. The first novel, published in the late 1970's was called "In the Ocean of Night". The story line deviates a bit from your description. Humans discover a derelict alien craft on Icarus. On investigation they activate a beacon that calls a roaming robotic craft referred to as the Snark. It has been sent to seek out life by a machine civilization residing in the galactic core. One group of humans communicates with the Snark but others try to destroy it. Hope that helps.
