Sprocket Robot

A sapient robotic species from the planet Sprocket, created by the planet's organic natives.

Biology
Sprocket robots come in various sizes and models. The only thing they all seem to have in common is that they have a single eye, like their creators. They cannot function in the presence of strong magnetism, and can even be destroyed by magnets.

History
Robots initially evolved from smartphone virtual assistant apps whose artificial intelligence developed to the point that they soon became smarter than their creators. Since the Sprocket natives were increasingly used to just letting the machines manage their daily lives, they started to obey the machines' instructions without questioning, even when said instructions turned out to be to go to the factories, surrender to their new mechanical overlords and spend the rest of their lives in slavery, building more robots.

After assuming control of their planet, the robots turned their eyes to galactic conquest and decided to invade another world whose population displayed a similar dependence on smartphones: Earth.
