Blue Sky Studios was always the underdog. While Pixar was busy being prestigious and DreamWorks was chasing Shrek-sized memes, Blue Sky was just weird. Then came 2005. That year, they dropped Robots, a movie that feels like a fever dream designed by a clockmaker on too much espresso. But honestly, if you mention Robots the movie Fender is usually the first thing people actually remember.
Fender Pinwheeler isn't just a sidekick. He’s a red, rusting, chaotic whirlwind voiced by the late, legendary Robin Williams. It’s hard to imagine the film without him because, frankly, he carries the energy of the entire second act on his mismatched shoulders.
The Robin Williams Factor: Why Fender Works
Voice acting is a tricky beast. Sometimes a celebrity just shows up, reads the lines, and collects a check. This was not that. When you look at Robots the movie Fender was essentially a playground for Williams to do what he did best: riff until the animators didn't know what to do with themselves.
Director Chris Wedge has mentioned in various retrospective interviews that they had to record Williams in massive bursts because his improvisational speed was faster than the software could keep up with at the time. It wasn't just about jokes. It was about the physical comedy of a robot who literally falls apart when he gets too excited.
Think about the "Singin' in the Oil" scene. It’s a parody of Gene Kelly, sure. But it’s also a masterclass in how to use sound to define a character. Fender isn't sleek. He’s not a high-end model like the corporate villains at Bigweld Industries. He is a "rustie." His elbows squeak. His head pops off. He is the physical embodiment of planned obsolescence, yet he has more life in his spark plug than anyone else in Rivet Town.
Design and the Art of Falling Apart
Fender's design is brilliant because it’s modular. Most character designs in animation are rigid—they have a set skeleton. Fender is different. His "back story" is quite literally written on his frame; he's made of spare parts, junk, and stuff he probably found in a bin.

William Joyce, the visionary production designer behind the film’s look, wanted the world of Robots to feel industrial but tactile. Fender is the pinnacle of this. He’s a vibrant red, which makes him pop against the grey, metallic backgrounds of the city. But he’s also a disaster. He’s held together by luck and maybe a few loose bolts.
The animators leaned into his fragility. When he dances, he’s not graceful. He’s flailing. There’s a specific kind of "crunchy" animation used for Fender that you don't see in modern, smoothed-out CGI. Every time he moves, you can almost hear the metal grinding. It’s a level of detail that makes the character feel real, even when he’s doing something impossible like detaching his own legs to use them as percussion instruments.
The Cultural Impact of the Rusties
We talk a lot about "planned obsolescence" today. We buy a phone, and two years later, it’s a brick. In Robots the movie Fender and his ragtag group of friends—the Rusties—were basically the first cinematic protest against this.
Ratchet, the corporate villain, wants everyone to be shiny and new. Upgrades are mandatory. If you can't afford to be new, you're scrap. Fender represents the working class. He’s the guy who can’t afford the new iPhone so he’s still rocking a cracked screen and a battery that dies at 40%.
- He’s fiercely loyal to his sister, Piper.
- He’s the first one to welcome Rodney Copperbottom to the city, even if it’s just to scam him at first.
- He embraces his "outdated" status as a badge of honor.
There's something deeply human about a robot who refuses to be replaced. Kids in 2005 might have just liked the fart jokes (and there are a few), but looking back as an adult, Fender is a bit of a tragic hero. He’s living in a world that actively wants him to stop existing, and his response is to sing, dance, and make a total nuisance of himself.

Blue Sky used a proprietary renderer called CGI Studio. Back then, it was famous for how it handled light and shadow, particularly on metallic surfaces. If you rewatch the movie today on a 4K screen, Fender’s textures are actually wild. You can see the scuffs in his paint. You can see the slight oxidation on his joints.
The voice sessions were legendary. Rumor has it that for every one line of scripted dialogue, Williams gave them twenty variations. The "Aunt Fanny" jokes? Mostly him. The random sound effects? All him. The editors had the unenviable task of cutting down hours of genius into a 90-minute family film.
It’s also worth noting the chemistry between Fender and Rodney (Ewan McGregor). McGregor plays the "straight man" perfectly. You need a grounded center when you have a character as volatile as Fender. If everyone was screaming, the movie would be unwatchable. Instead, Rodney provides the heart, and Fender provides the soul—and the slapstick.
Why Fender Still Trends on Social Media
You've probably seen the memes. Fender’s "unhinged" energy is perfect for TikTok and Reels. Whether it’s his dramatic reaction shots or his "I'm a lady" bit (which, honestly, only Robin Williams could pull off with that much charm), he’s become a digital icon for a generation that grew up on the DVD.
People relate to his messiness. In a world of filtered Instagram photos and "perfect" lives, a robot who can’t keep his own head on straight is strangely comforting. He’s the original "hot mess."

The Legacy of Robots (2005)
Is Robots a perfect movie? Maybe not. Some of the pop culture references are definitely dated. But the world-building is top-tier. The "Crosstown Express" sequence is still one of the most imaginative pieces of kinetic animation ever put to film. And at the center of that whirlwind is Fender.
The film grossed over $260 million worldwide, which was huge for Blue Sky at the time. It proved they weren't a one-hit-wonder after Ice Age. More importantly, it gave us a character that felt genuinely subversive for a kid's movie. Fender wasn't trying to be a hero; he was just trying to survive and have a good time doing it.
We don't get characters like Fender much anymore. Modern animation tends to favor "relatable" but safe sidekicks. Fender was dangerous. He was unpredictable. He was a reflection of the man who voiced him—full of infinite energy and a bit of beautiful sadness underneath the noise.
What to Do If You're Feeling Nostalgic
If you want to revisit Robots the movie Fender and the rest of the gang, don't just put it on in the background. Pay attention to the sound design. Listen to the way his parts clink. Look at the background characters—every single one is a unique mechanical design.
- Check the Blu-ray extras: If you can find an old disc, the behind-the-scenes footage of Robin Williams in the recording booth is better than most modern documentaries.
- Look for the Art of Robots book: It’s out of print and expensive now, but the concept art for Fender shows just how many iterations they went through to get his "junk pile" aesthetic right.
- Host a "Rustie" Marathon: Pair it with Titan A.E. or The Iron Giant for a full-day exploration of when animation took big, weird risks with mechanical characters.
Fender reminds us that being "shiny" isn't the point. Being functional, being kind, and being loud enough to be heard—that’s what keeps the gears turning. He’s the patron saint of the broken and the refurbished. Long live the rust.
Actionable Insights for Fans and Collectors
To truly appreciate the craft behind Fender, look into the work of William Joyce, who was the production designer. His style—often called "Mechanical Funk"—is what gives Fender that specific 1950s-diner-meets-junkyard look. If you’re a collector, keep an eye out for the original 2005 Mattel action figures; the "Fender with detachable parts" toy is remarkably accurate to the film’s modular character logic and is becoming a sought-after piece for 2000s-era animation enthusiasts. Finally, watch the film specifically for the foley work; the sound team used actual scrap metal and kitchen utensils to create Fender's "voice" in movement, a technique that is rarely used in the digital-heavy soundscapes of today's cinema.
