Robota is an illustrated book by Doug Chiang and Orson Scott Card about a mysterious fourth planet of the solar system named Orpheus.
In a time before the events of the book, an alien race known as the Olm came to Orpheus and warned the people, explaining that their planet will crash into Earth in several thousand years.
The Olm gave humans very advanced technology and the ability to create robots with artificial intelligence. But over the centuries, entropy and mismanagement have taken their toll.
