Norby the Mixed-Up Robot — Janet Asimov

Meet Norby -- he wants to help, but he's one mixed-up robot! When Space Academy cadet Jeff Wells needs tutoring for his course in Martian Swahili, he goes looking for a robot teacher. Norby possesses not only the usual robot skills but also an extraordinary array of powers, including antigravity and hyperspace capabilities. He's just a little fuzzy on how to use his gifts! Together, the boy and the robot must figure out a way to foil a sinister plot involving Ing the Ingrate, would-be Emperor of the Universe.
The first book of TheNorby Chronicles, this novel was written by Janet Asimov and her husband, Isaac Asimov -- the author of I, Robot and many other robot stories. It's a great way to introduce young readers to the thrills of science fiction.
