Rosie

Rosie is the robot maid for the Jetsons in their Skypad Apartments home, quickly becoming a member of the family.

Her model number is XB-500. Though there have been more models made after Rosie's (thus technically making her "outdated"), the Jetson family loves her too much to trade her in for a newer model.

Early life
Her predecessor model was an XB-400, nicknamed "Norma", which Rosie considered to be her mother.

Notes/trivia

 * In the development of the series in the 1960s, "Rosie" was spelt "Rosey," which was repeated when the season 1 episodes were given title cards when the show was revived 20 years later. However, the then new season two episodes spelt her name as "Rosie" which continued in Jetsons: The Movie and The Jetsons & WWE: Robo-WrestleMania. In spite of this change, a season 3 title card goes back to using "Rosey."
 * She is excluded from the title cards, even though she had significantly more appearances in seasons two and three.
 * According to Jane in "S'No Relative", Rosie gets time off.
