Norby, the Mixed-Up Robot

Norby, the Mixed-Up Robot is the first book in the Norby series by American authors 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.
