Norby, the Mixed-Up Robot (1983, Walker & Company) is the first book in the Norby series by Janet Asimov and Isaac Asimov. In it, Jefferson Wells and Norby stop Ing from taking over the Solar System with the help of Jeff's brother Fargo Wells, police officer Albany Jones, and Admiral Boris Yobo. According to Isaac Asimov, although Janet Asimov did 90% of the work, his "name was wanted on the book for the betterment of sales [and he] went over the manuscript and polished it a bit." It, along with its sequel, was illustrated for Boys' Life. Plot summary The book starts with Jeff Wells, a cadet at a military academy on Mars in need of a teaching robot, for although he is not flunking, his substandard grades have caused concern for Commander Widlow, who has also pointed out that the Wells family has lost their fortune and his tuition is overdue, ergo termination is recommended.

As the academy has ended for summer, Jeff returns to Earth, where he buys a small, fat robot only to discover that it has the only mini-anti-gravity device in existence.

Norby and Jeff go to the park where the evil villain Ing's henchmen are after Fargo Wells, Jeff's brother. Norby and Jeff stop the henchmen who are captured by the police. The policewoman in charge of the squad identifies herself as Albany Jones, whom Fargo knew from his days at Neil Armstrong High School. Ing manages to take over Manhattan Island, renaming it the "Kingdom of Ing", but Norby and Jeff start a revolt against him with the aid of a dowdy woman whom they save from being arrested. However, as Ing's soldiers are about to capture Jeff, Norby absconds using a hyperdrive, never before done and creating a subplot for the second book in the series Norby's Other Secret, as they end up in a jungle planet named Jamya. Norby uses the hyperdrive to return to Earth, where they enlist
