While there was no great need here now to create "soul-ful" advanced computer brainy robots, possibly some would become useful in the future to send to alien stars. Yet, any could be shut-down during such a long trip, of course speeding at most at a fraction of light speed (in the real universe). Thus a smaller much less wide interstellar vessel would be fine, not needing any food, nor any heating and living energy supplies, thus much safely smaller for avoiding interstellar space debris. Once reaching a destination star, robots could harness energy from included initial sunlight to electricity transforming films, to begin many activities, after first finding a good asteroid nicely usable for constructing lots of wanted things there.
