In the ultraconvenient and chromatic world of The Jetsons, the robots are fully sentient beings and are equal to humans. There are lots and lots of robot characters; some are simply plot devices for an episode, and others are practically family to the Jetsons. Elroy Jetson has a robot teacher, Judy has a robot diary, Jane has a best friend and housekeeper robot, and George has plenty of robot coworkers. Robots assist the citizens of Orbit City with every aspect of life and keep the city in the sky happy and functioning.
