Norby and the Invaders & Norby and the Queen's Necklace

Norby was originally a robot named the Searcher, created far from Earth on the planet Jamya. When he's sent on a mission to find fuel for his fellow robots, he crashes in Earth's asteroid belt. Norby was stranded--until he was found by a salvager and put up for sale as a teaching robot. That's how he ended up in the possession of Space Academy cadet Jeff Wells. But Norby has far more than the typical robot features. He has an extraordinary array of powers, including antigravity, time travel, and hyperspace capabilities. Together he and Jeff embark on a series of adventures that require them to use every ounce of bravery and imagination to make it through, from facing villains to finding the missing princess of the planet of Izz.
