It is an odd idea- a robot ship with a crew. Does it not need an engineering crew? No operations crew at all? Does this robot ship just carry people to be embarked in some way? A mission team? Does it fit the multi-use type described for Antares? Survey, science, cargo? Survey and science are the mission team. Cargo is the robot job. Maybe it works. It might make some sense of a senseless jumble of types in the script. But however you stack it, it’s a bit weird. If it does work, the polygonal habitat module, as weird as it is, highlights the odd marriage. If you aren’t going to use the crewed ship - Huron - for Antares, then I guess this makes the next best sense.
