The evolution of Astro Bot’s adorable character design

From the moment he popped out of our transformed DualShock DualShock 4 wireless controllers in Playroom VR, it was clear that Astro Bot was going to charm hearts across the galaxy. Eight years later, this amazing character is truly ready to step into the spotlight via his titular PS5 adventure – Astro Bot. So we sat down with Team Asobi’s studio director Nicolas Doucet to get into the nuts and bolts of the origins and evolution of this iconic PlayStation mascot-in-the-making.

The Playroom

Birthing baby robots

The very first conception of Astro Bot emerged from Team Asobi’s desire to experiment with the DualShock 4 controller connection with the PS4 camera, crafting a demo provisionally titled Little AR (Augmented Reality) Men. The main characters were initially tiny robots that you could interact with on your living room floor.

“That was really the starting point,” says Doucet. “At the time we didn’t have any art, so we made prototypes out of primitive shapes. The characters were just robots made up of cylinders with little eyes. Eventually we renamed them to AR Bots.

“We worked with artists to bring these characters to life, but we only had five months to implement the demo into The Playroom. So to make them sci-fi looking within such a short period of time, we gave them a Sony robotics style. But it was also important that they were endearing, so we gave them big cute eyes and made them waddle like toddlers, so they kinda became baby robots.”

The Playroom VR

From AR Bots to Astro Bot

As the AR Bots became customized as part of The Playroom’s evolution into The Playroom VR, Astro Bot himself emerged needing a more central character to control for a VR platformer prototype, which became the Robots Rescue mini-game.

“We internally called him Captain Astro,” explains Doucet. “We added a PlayStation blue livery and more parts to have him stand out from the environment, gave him the ability to hover and modified his hands to grab things.

Astro Bot Rescue Mission

“He also had to feel tangible for VR. We looked at him as if he was a real-life robotics product – it’s a character you can take apart and understand how his joints come together.”

It wasn’t until 2018’s solo PS VR platformer, Astro Bot Rescue Mission, that Astro officially claimed his name – and with it came with the help of animation and art talent from other development teams, including Gravity Rush and The Last Guardian.

A cache of the minutiae

Making sure Astro was primed for his full solo escapade in Astro Bot Rescue Mission meant tweaking his design, both from a visual and gameplay perspective. Already gifted with classic platformer design considerations – a low center of gravity and a compact frame – Astro benefited from several little details, some made even more distinctive in Astro Bot:

Eyes
Astro’s blue LED eyes are key to his facial expressions, changing shape to convey a variety of emotions – but they’re also fundamental to the VIP Bots in the game. More on that point, later…

Jetpack
“In the original design whenever Astro hovered, two little wings came out of his back for him to glide,” says Doucet. “You don’t really notice them, but we wanted to create a rationale behind the function.”

Chrome dome
Astro Bot’s star shines in more ways than one, with the plate on his head subtly showing off the dazzling power afforded by PS5. From jungles to oceans, all the game’s environments are now fully reflected on the back of Astro’s silver head plating during his travels.

Robo voice
We might think Astro’s cute, high-pitched voice was a natural decision, but lots of thought went into what he can say, to the point that he’s secretly a bit of a polyglot. “Astro fundamentally does not talk but his sounds do mix English and Japanese, but also universal words and onomatopoeia, masked into robotic sounds,” says Doucet. “He’s being played by kids all over the world, so we also had to think about sonority, sounds and syllables that work for as many languages as possible.”

Expanding Astro’s world

It’s things like Astro’s reflective head plate that symbolizes his growth over the years, now unlocked for PS5. Being in 4K has meant more detail and higher fidelity across the board with a compatible 4K TV or display, making Astro and his companions pop, something that extends even to the game’s flora and fauna.

“There’s a lot of wildlife – about 70 new animals in this game,” says Doucet. “From frogs and small insects, to polar bears and elephants, and they all follow the design language of the bots with LED eyes. Even power-ups like Barkster the bulldog booster have the same traits. So the idea of blue LEDs for friends and red LEDs for enemies has become something of a trademark we’ve built on.”

‘Steeling’ some beloved PlayStation characters

And then there are the VIP and Cameo Bots – in-game versions of popular PlayStation-related characters – that had players buzzing with delight at their reveal. The franchise isn’t a stranger to cameos, but Astro Bot takes it even further, with a staggering amount of consideration given to integrating its robotic tributes to Kratos, Aloy, Nathan Drake, and many others.

“They had to be a cool sci-fi design but also have things like fabrics or furry boots, so we sometimes felt we might be going against the original intent of the character,” explains Doucet. “So we substituted more organic materials, like hair, with materials such as vinyl.

“But with all of these characters, the eyes are paramount. Sometimes LED eyes just didn’t work on certain characters because the original design relies so much on the pupils being a certain size or color for instance . So for more cartoony VIPs like Crash Bandicoot or from Ape Escape, the Bots are wearing a mask to help bridge that problem!”
