The story chronicles the adventures of Lighty and his friends in Robocity, a place inaccessible to other creatures and populated by extraordinary beings called Robichi.

Robichi are thinking robots who perform all normal daily activities on a par with humans.

Before the Assembly Day, when the Robichi become honorary citizens through a device that grants a special power, Lighty makes a sensational discovery that will completely change his life and the lives of all Robichi.

Omicron, twin brother of the Governor, seeks to free the city from Ypsilon’s tyranny; in doing so, Omicron will be aided by Hertz, the Governor’s loyal assistant.

Robocity is not anymore the peaceful and safe city it was thought to be because Governor Ypsilon has not only the power but also the technology to dominate the Robichi mentally.

Lighty and friends must save the city from the evil ruler, deactivate the central control system and free Robocity from the holographic dome that overwhelms it.

The story harkens back to the struggle between good and evil and teaches us that through friendship and good deeds we can more easily achieve our goals and perhaps save the world.
