In the distant and desolate future, a lone robot awaits rebooting. Robo is dependable, polite, strong and will fulfill his programming no matter the cost. He becomes especially close with Lucca, as he further proves to her that machines can have a heart, in a sense. Robo is pure in every sense of the word. There is no one more reliable. 

For Robo's voice, we are looking for something that sounds mechanical and processed, but not to a point that it becomes grating for listeners. Try to achieve a balance between robotic and somewhat human!
