Airbus Is Steering Its Mars Rover With a Steam Deck
Airbus let documentarian Tom Scott drive its ExoMars rover prototype, and the device in his hands wasn’t a bespoke control rig with six screens and a joystick the size of a lamp — it was a modified Steam Deck. The team at Airbus’s Stevenage campus is doing autonomous navigation work on the rover, apparently running custom software off Valve’s handheld, and a bumper press pivots the wheels 90 degrees to sidestep a turning circle entirely.
Strip away the novelty and there’s a real signal here. When aerospace engineers need an intuitive physical interface for a remote operator, the answer that won out was a commodity handheld PC running Linux — not a custom-built controller.
Why Airbus Reached for Off-the-Shelf Hardware Instead of a Custom Rig
The practical case is easy to make. A Steam Deck already ships with dual thumbsticks, a full face-button cluster, two trackpads, four shoulder inputs, gyro, and a 7-inch screen — all in a package that already exists, already has mature Linux drivers, and can run a custom application without an engineering team spinning a custom PCB. Building that from scratch would be months of work for something a consumer device does out of the box.
The source doesn’t say whether this is the LCD or OLED model — PC Gamer’s writer figures it looks like the standard version — and Airbus hasn’t detailed any hardware modifications beyond calling it ‘modified.’ So treat the specifics loosely. What matters is the class of device: handheld PCs have quietly become legitimate general-purpose control terminals, not just gaming machines. That’s the same reason you see Decks and Allys cropping up in workshops, on film sets, and in field diagnostics. Walt Disney Imagineering has already been spotted driving an animatronic from one, and that wasn’t a sponsored stunt either. The form factor is an input surface first and a console second.
The Bumper-Turn Trick Is a Constraint Design Lesson Handhelds Teach Constantly
That 90-degree wheel pivot mapped to a single bumper press is the most interesting detail in the whole story. Airbus didn’t model a turning radius; it designed a control scheme that makes turning unnecessary. That’s the exact discipline handheld developers live by — you can’t give a player a keyboard’s worth of inputs, so you map complex actions to a few well-chosen buttons and trust the player to build the muscle memory.
It’s the same reason a Deck-friendly RTS leans on trackpad-as-mouse, or why driving games that feel clumsy on a gamepad feel natural once you remap throttle to a trigger with good travel — and why a mouse-first PC port like Happy Wheels needs a trackpad layout before it feels right. Good control design isn’t about cramming in more inputs; it’s about finding the one press that removes a whole category of problems. Airbus arrived at that conclusion for a rover on a Mars test bed. Handheld players arrive at it every time they open a remap menu.
The rover itself won’t be driven this way when Rosalind Franklin launches toward Mars in 2030 — autonomous navigation takes over long before touchdown, and there’s no gamer den on the landing platform. But it’s worth remembering the next time someone frames handheld PCs as a novelty: the hardware has already graduated from a consumer gadget to a tool serious engineers pick when they need one. Expect more of this, not less.
