RC-101 was a series of labor droids that were designed to carry luggage to and from locations in a spaceport. They were often referred to as "redcaps."
RC-101 droids made during the era of the Clone Wars were designed with a hamper to carry luggage. They were also largely involved in helping Rinsoos (Republic Mobile Surgical Units) since the First Battle of Geonosis, and were prevalent as far as remote worlds like Drongar.
