The craft was named a "shuttle drone" in the Star Trek: The Next Generation Companion (3rd ed., p.240).
According to the Companion, the small, six inch long shuttle drone was built "quick-and-dirty" by Dan Curry using disposable Gillette razor handles as nacelles. Curry noted on his build, "For example, when the Enterprise is in Dry-dock a small utility vessel passes by. It is actually a broken toy robot foot embellished with throw-away razor handles glued to it. We didn't have much time and used whatever was available to do the job. The makers of everyday objects do a great job of precise industrial design and manufacturing. If you can look at things independent of their actual size you will discover that the world is filled with space ship parts." Though small, a behind-the-scenes picture on Larry Nemecek's Blog revealed that the model was rigged with internal lighting as was also shown in the Reading Rainbow's episode "The Bionic Bunny Show", where the model was featured. Curry has retained the small model, and it is currently part of his personal collection. (TNG Season 6 DVD-special feature "Dan Curry Profile")
