Motion
Six direct-drive motors on three motor blocks, six connecting rods, three pneumatic legs carrying the standing load, and the platform itself.

Built for how
you'll use it.
Pick the build that is right for you, and change anything before you order. Every PDK shares the same direct-drive core, the same patented weight compensation, and the same six axes. What differs is how much of the rig around it we build for you.
01 · PDK · $4,899.99
Ready to build on.
Three motor blocks, six direct-drive motors, three pneumatic legs. Nothing on top dictating what you build.
02 · PDK + Extension Feet & Table · $5,299.99
Solid ground.
Just as open as the PDK, now on extension feet with the two-piece wood table fitted. Put anything on it, stand it anywhere.
03 · PDK Racer · $6,299.99
Designed for the forces.
A racing chassis and three stabiliser feet, braced around the platform. Bring your own wheel and pedals — it is built to take them.
04 · PDK + ARK Ecosystem · $8,499.99
The ultimate sim rig.
Platform, chassis, wheelbase, wheel, load-cell pedals and button box — matched and tuned as one system. Nothing to source, nothing to guess.

Before you order
- What is covered — 24-month Limited Warranty on the kit, from delivery. Cancel any time before dispatch for a full refund. Consumers may also return it within 14 days of delivery, any reason.
- Where we ship today — ordering is open for the United States. Europe (EU/EEA) and the rest of the world are opening soon: both are sold by our Cyprus company, and we are waiting on its payment account to clear before we can take an order. European orders are priced in euros with VAT and import duty included; everywhere outside the EU/EEA, in US dollars. The region you choose sets the price and the tax basis. If you are outside the United States, write to us and we will tell you the day it opens.
- Who you buy from — it depends on where it ships. To the United States: ARK Dynamics Global, a Wyoming corporation, in USD. To the EU/EEA and the rest of the world: ARKINEMATICS LIMITED, a Cyprus company — in euros for the EU/EEA, VAT and import duty included, and in USD elsewhere. ARKINEMATICS is also our EU authorised representative for product safety and our EU data-protection representative. Your seller and your total are named on your order confirmation.
- When it is ready — expected 3 to 6 months from order confirmation; delays of up to 12 months beyond that are possible. You can cancel any time before dispatch for a full refund, and if your Kit has not shipped within 12 months after that window we refund you automatically, without you asking. Paid in full at order.
- Changing your mind — cancel any time before dispatch for a full refund. Consumers may also return the kit within 14 days of delivery for any reason; you pay the return carriage to our US return address, about USD 500 by sea, and more from remote addresses.
- Paying over time — where available, you can pay monthly with Affirm or Klarna, offered at checkout. Approval is theirs, not ours, and the order is placed only once they accept the payment. Which methods you see depends on your country, so they will not appear everywhere.
- The contract — Terms of Sale & Use and Shipping Policy. The Terms include the model withdrawal form.

Grid-position holders
Your code prices three builds.
Grid positions are no longer sold, and nothing is charged to hold one. If you already have a position we email you a personal code, tied to your email address and usable once. It applies to three builds — the PDK, the PDK + Extension Feet & Table and the PDK + ARK Ecosystem — and entering it in the order card above reprices the build on the spot. The PDK Racer is the one build it cannot move.
In the box
Everything you need. Nothing you don't.
Every PDK ships as the complete motion platform. No additional hardware is required to make it move.
Power & control
Drives, the housekeeper and motion-cueing processors, the capacitor bank, the universal-input supply, the onboard router, and all cabling.
Tuning
A browser dashboard served from the platform's own router. Nothing to install, reachable from any device on your network.
Seven boxes, none over 26 kg. The full component list is on the Ecosystem page.
Built for precision
Where motion fidelity is not negotiable.
Feel the kerb texture, not just the kerb
21-bit resolution reproduces surface detail conventional platforms round away. Used for driver training, team development, and by people who can tell the difference.
The complete motion vocabulary of flight
All six axes — fixed-wing, rotary and UAV. Pneumatic weight compensation makes an extended session practical without the motors heating up under a static load.
Motion before the mismatch
Discomfort in immersive work is a timing problem, not an intensity one. The platform's own contribution is under 1 ms, command to actuator.
Research-grade, citable, patented
Documented encoder resolution, a characterised envelope traceable to the firmware, and a patent number you can look up. Suitable for vestibular, biomechanics and human-factors work.
A platform you can actually get inside
FlyPT Mover as the usual route in — free, and with a large community sharing profiles. Direct CAN access underneath it for your own implementation.
Designed to be embedded
No lock-in. If you are building something the PDK was not designed for, we would like to hear about it.
After it arrives
You're not on your own.
Every kit ships with its Safety Manual and Installation Guide, and the team answers order and build questions directly. Kinemaniacs — the community site where PDK owners will share build notes, tuning profiles and FlyPT Mover configurations — is in development and opens from here.
What arrives
Everything in the box.
Seven boxes, none over 26 kg, so one person can carry the machine in. Fourteen steps from the first foot on the floor to the steering assembly.
Component 03
Before you decide
What you are agreeing to, in plain terms.
Do I need to assemble it?
Yes. The kit arrives as pre-assembled modules in seven boxes, none over 26 kg, and bolts together in fourteen steps, feet first. One person can do it. The Safety Manual and Installation Guide ship with the kit; the Kinemaniacs community site, where owners will share build notes and tuning profiles, is in development.
When does it ship?
Expected 3 to 6 months from order confirmation. Delays of up to 12 months beyond that are possible. You can cancel for a full refund at any time before dispatch.
Who is my contract with?
Delivery to the USA is contracted by ARK Dynamics Global (Wyoming), in USD. Delivery to the EU/EEA and the rest of the world is contracted by ARKINEMATICS LIMITED (Cyprus) — in euros for the EU/EEA, with VAT and import duty included, and in USD for the rest of the world. ARKINEMATICS is also our EU authorised representative for product safety and our EU data-protection representative.
What does the patent cover?
Adjustments to the Stewart platform that separate weight-bearing from positioning: a pneumatic actuator carries the load and a direct-drive actuator does the moving. Canadian patent CA 3217174 C, granted 11 February 2025. Read the patent page
