Rotus
ONE MECHANISM. ZERO BLOCKED BUTTONS.
ROTUS
Apparatus
A mechanical steering apparatus that brings pistol-grip precision to game console controllers. Designed in Istanbul, hand-assembled with hybrid manufacturing.
Rotus is a steering wheel attachment for the Xbox controller. A V-shaped steering arm clips onto the lower-center face of the controller with a mechanical and magnetic lock, in about one second, with no screws. Your hand only touches the grip points, so no face button or bumper is blocked and the left stick stays free — which is why it also works for one-handed and adaptive play. Built for sim racing on a controller: Dirt Rally, Forza, SnowRunner, without a wheel stand or a full sim rig.

Mounts on the controller. Blocks nothing on it.
The V-shaped steering arm sits on the lower-center face of the controller. Your hand only touches the grip points — no button is ever blocked.

GG GRANT // Free Accessibility Program
GG Spirit sales fund a free version of Rotus for players with limb loss or functional difficulty.
Bizim için erişilebilirlik, mühendisliğin temel bir borcudur. GG Grant programı, Rotus'u ticari bir ürün olmanın ötesine taşır. Parmak ve el kaybı yaşayan veya el işlevinde güçlük çeken arkadaşlarımız için bu teknoloji tamamen ücretsizdir. GG Spirit satışlarından elde edilen kaynaklar bu programı finanse ederek oyun dünyasındaki engelleri mekanik avantajlarla kaldırmamızı sağlar. Eğer bu performansa ihtiyacınız varsa, belge sormuyoruz; adını ve e-postanı bırak, gerisini birlikte konuşuruz. Asıl kanalımız bireysel taleplerin bize ulaşmasını beklemek değil — el veya parmak kaybı yaşayan ya da el işlevinde güçlük çeken bireylerle zaten çalışan üniversiteler ve kurumlarla doğrudan iş birliği kurmak. Böylece bize hiçbir zaman ulaşamayacak kişilere de erişebiliyoruz. Bu sayfadan bireysel başvurular da paralel olarak açık kalıyor, ama her GG Grant biriminin gerçekten ihtiyacı olan birine ulaşmasını asıl sağlayan kurumsal ortaklıklar.
WHO CAN APPLY
01 El veya parmak kaybı yaşayanlar
02 Motor beceri güçlüğü çekenler
03 Onlar adına başvuran aile üyeleri veya bakım verenler
04 Belge gerekmez — başvurudan sonra durumunu konuşmak için biz ulaşıyoruz

OUR STORY // VEDAT, ISTANBUL
We Just Wanted a Real Steering Wheel.
I'm Vedat, founder of Vulu Design. I'm not an engineer — I'm a music producer and DJ. But I'm a rally addict, mostly playing Dirt Rally. Dirt Rally or GTA, it didn't matter — whenever I tried fast, precise maneuvers in a game, I hit the same wall: the standard controller's thumbstick can't give you a real steering wheel's precision, and a full wheel setup is expensive and takes up space. This wasn't just my problem — it's every controller player's problem.
My idea was clear: bring the "pistol-grip" fine-control feel of RC cars to a standard Xbox controller with a cheap, portable add-on — an affordable, practical alternative to sim-racing. I turned a small corner of my Istanbul apartment into a workshop and got to work. I had no design background, no 3D printing experience. With calipers in hand and a few 3D printers around me, I printed 300+ prototypes — gears, bodies, parts I designed specifically for Rotus. Setbacks shelved the project more than once; the back-and-forth development took over three years.
While developing, I noticed something I hadn't expected: the mechanism also let you control the game one-handed — a side effect I never planned. Then a message came from Yusuf: "Because of this I can play games." That message brought the shelved, dormant project back into my hands. Today Rotus is a system that locks onto an Xbox controller magnetically, eliminating analog drift with Ghost architecture and a torque-limiting mechanism. Accessibility was a discovery for me, not the origin — but today it's a real, central part of Rotus and Vulu Design.

FAQ // BEFORE YOU ASK
When will Rotus ship?
We're targeting November 2026 for the first production run — if the schedule shifts, everyone on the waitlist hears about it first.
Am I paying anything now?
No. The waitlist takes no payment and creates no obligation. We use it to size the first run and to tell you when it opens.
Which controllers does it fit?
The Xbox Series X controller is supported in production today. Xbox Series S, Xbox One and PS5 versions are in development, with no date yet.
Does it block any buttons?
No. The Ghost architecture sits on the lower-center face of the controller — A/B/X/Y, triggers, bumpers, d-pad and the right stick stay fully accessible.
How does the GG Grant work?
Adını ve e-postanı bırakıyorsun; durumunu konuşmak için sana biz ulaşıyoruz. Belge istemiyoruz. Programı GG Spirit satışları finanse ediyor ve kapsama giren kişiler için Rotus tamamen ücretsiz.
Do you ship outside Turkey?
Rotus is assembled in Istanbul. International shipping is planned for the first run — countries and costs will be announced to the waitlist.
Is Rotus a steering wheel for the Xbox controller?
Yes. It is a compact mechanical steering wheel attachment that mounts on the controller itself, not a desk wheel. It gives you a real rotating steering axis with pistol-grip precision while keeping every button reachable.
Do I need a wheel stand or a clamp?
No. Rotus attaches directly to the controller and adds about 41 grams. There is nothing to mount to a desk. You hold the controller the way you always do; the steering arm sits under your fingertips.
