Rodney Copperbottom is the main protagonist of the film Robots. He is the son of dishwasher Herb Copperbottom and his wife, Lydia. Rodney is an aspiring inventor who idolizes the famous Bigweld. Rodney's dream is to go to Robot City to work as an inventor for Bigweld Industries. He is voiced by Ewan McGregor.
Rodney appears early in the film and home console game as a child, though early on he is upgraded to his adult body, which he has for the rest of the film and game. Generally, he appears as a thin humanoid robot who has a blue-green color scheme with white highlights and brown-gray insides.
As a child, he has a body emulating a humanoid child. His proportions are so that his torso is about as long as his legs.
As an adult, his body is obviously taller. His legs have been replaced with longer ones that appear to have a spring in each of them. His body proportions have been altered so that his torso is shorter than his legs.
Rodney Copperbottom was born in Rivet Town to Herb and Lydia Copperbottom. As a child, Rodney and his father watched a TV show hosted by the inventor and industrialist, Bigweld, who talked about his company who would hire new inventors who created newer technologies for robots. Inspired by Bigweld and his motto, "You can shine no matter what you're made of," Rodney wanted to become an inventor like him.
