QX-1, as can be guessed by his odd designation, has the distinction of never being a stock R2 unit. He was built from scratch by Gerred Garvin, a well-known engineer for Industrial Automation and father of Tav Garvin, to help his family out around the house while he worked long hours for the company. Gerred opted for an R2 unit instead of one of IA’s household models for several reasons, not the least of which was the R2 unit’s known reliability and versatility, but the biggest was that he knew his son Tav would get a kick out of having an astromech in the house.
