Rodney Copperbottom/Trivia

* After Rodney is dumped outside Bigweld Industries by the giant magnet, all the metal shavings from the slogan sign stick to his head, just like the old-time Magnetic Face toys.
* Rodney's design is inspired by an old Evinrude outboard engine in Chris Wedge's garage, as well as on a Volkswagen van. An early version of Rodney makes a cameo, as the green robot with the jet pack, waiting in line during Bigweld's television show.
* The net weight of the box in which the baby is delivered is 3.5 kilograms. This would mean that Rodney would have a birth weight of seven pounds, and eleven ounces.
* At one point, a voicebox with a recording of Darth Vader's voice is found. Ewan McGregor, the voice of Rodney, played a younger Obi-Wan Kenobi in the Star Wars prequel trilogy, in which Revenge of the Sith, the third episode and final installment of the prequel trilogy, was released in 2005, the same year as Robots, and releasing 2 months after the release of the film.
* Ewan McGregor used an American accent to portray Rodney.
* Robots is the first film in which Stanley Tucci and Ewan McGregor voice animated characters, the second being the live-action Beauty and the Beast (2017).
* Chris Pine, Zachary Levi, David Spade, Leonardo DiCaprio, Michael J. Fox, Sam Huntington, D.B. Sweeney, Hugh Jackman, Jim Carrey, Mike Myers, Tobey Maguire, James Franco, Matthew Fox, Matthew McConaughey, James Marsden, Topher Grace, and Sean Faris were considered for the role of Rodney.
* Ewan McGregor's first time voice acting in a theatrical film. Later he'd go onto voice the titular character of Valiant (2005), Obi-Wan Kenobi's spirit in the Star Wars sequel trilogy, Lumiere the Candle in Beauty and the Beast (2017), and The Wish Collector in The Land of Sometimes.
* During the scene where Rodney arrives in Robot City for the first time, a robot that resembles Sid the Sloth (John Leguizamo) from the Ice Age franchise can be seen briefly in the background.
