3DOF Low Cost Systems

CKAS U2s 3DOF Motion Platform / Motion System

W3s 6DOF Motion System next to standard PC

CKAS Mechatronics has introduced the best compromise small scale personal 3 degree of freedom (3DOF) motion system or motion platform - the U2s, specifically directed at very low cost small scale mid fidelity motion simulator applications, such as commercial simulators, next generation consumer coin-operated arcade entertainment simulators, home built mid fidelity flight simulators or home built mid fidelity racing entertainment simulators   

The CKAS U2s 2DOF Motion System features a mere 120kg total weight, 800mm total width, and sits only 300mm high, therefore eliminating the need for any specialised stair or gangway for stepping up onto it. CKAS has used the knowledge it has developed for the heavier motion systems to design this unit, incorporating industry leading electronics, encoders and actuators. The expected life of the U2s is extremely high for its price point, and the maintenance requirements are minimal, especially important in commercial or consumer based applications.  The target market of the CKAS U2s 3DOF Motion System can be any of the following single seater applications:

  • Small Scale Compact Mid Fidelity Flight Training Devices for Commercial and Military applications
  • Small Scale Mid Fidelity Commercial Vehicle and Truck Driver Training Simulators
  • Small Scale Mid Fidelity Mining Equipment Simulators and Heavy Earth Moving Equipment Simulators
  • Small Scale Mid Fidelity Train Driver Simulators
  • Next Generation Unsupervised Coin-operated Motion Simulator Arcade Machines
  • Home Built Mid Fidelity Flight Simulators
  • Home Built Mid Fidelity Car Racing Simulators

As with all our Generation III capable motion systems, the U2s units have real-time Reverse Kinematics, Forward Kinematics and Full featured Washout Cueing Filters all completely "on-board" meaning that any client application can operate these systems at even the "vehicle acceleration" level completely independent of any other software (See Gen III Connectivity Matrix document for more information).

CKAS U2s Motion Platform (ready to use) - (U2sMP)

Ideal for OEM manufacturers of existing simulator products or home builders who are looking for a cost effective method to instantly add mid fidelity motion to an existing or new design. This unit is pre-built to CKAS standards, is USB plug and play straight out of the box, and fits the same form factor as the CKAS T2s 2DOF Motion System. The only assembly required is to bolt on whatever goes on top of the motion system. This unit comes with a 1 year faulty part return to base warranty (does not cover wear and tear)

 Optional Extras Available for the CKAS U2s 3DOF Motion Platform:

  1.  Wheel Kit (4 wheels) which can be raised and lowered to allow easy transport of units
  2. Ethernet interface for completely platform independant control

 All CKAS U2s 3DOF motion systems come with the following key features:

  • Fully Electric Actuation
  • USB plug and play (with Ethernet as option for completely platform/OS independant control)
  • Washout filters and acceleration onset cueing algorithms for:
    • Microsoft Flight Simulator FSX / ESP / Lockheed Martin Prepar3D
    • X-Plane 9/10
    • rFactor (v1.225 or higher) / rFactor2
    • iRacing
    • Generic custom user program or other systems with full washout cueing, inverse kinematics, forward kinematics and full diagnostics on board the motion system
  • Configurable to be connected directly to X-Sim to support over 40 other popular games such as Dirt/Dirt2/Dirt3 F1 2010/2011/2012/2013/2014 and many more
  • Basic Serial over USB or optionally UDP (over Ethernet or Local) interface for immediate connection to custom software
  • Very high speed update 100Hz motion controller for extremely smooth high fidelity response

Important information for Potential Customers:

Before purchasing any motion system product for home use from ANY manufacturer, please consider the following very important information, especially when considering competitor products to the U2s.

  • Robustness and Professional Design - CKAS systems are used by companies such as NASA USA, Australian Defence Forces and other Military contractors. Our systems are very serious in construction and design, and we use only the finest German Actuator hardware to make sure the system works as it has been designed. Our machines are all designed by professional engineers who are trained in developing robot structures, which are designed not only to "work once", but rather to endure fatigue, and perform for a long time with high fidelity. Many competitor systems are simply built by enthusiasts who have some great ideas, but lack the engineering skills to "design and manufacture" a system for consumer or professional use.
  • Realistic Simulation - All CKAS motion simulation algorithms are of the highest academic quality. Our algorithms are certified in commercial driving and aviation simulators, and offer the highest fidelity and response. Many competitor devices which require an independent screen that is not mounted to the motion system are not producing a simulator at all and are inappropriate for use by serious enthusiasts. This is especially bad when a large angle swing is also integrated into such units as it is HIGHLY unrealistic to be accelerating and trying to see the TV in front of you when you are tilted back and looking at the ceiling.
  • Replacement Parts and Spares - CKAS systems are designed with almost entirely "commercial off the shelf" (COTS) components, which are provided by large scale multinational manufacturers. This means that sourcing spare parts for our systems long into the future will be trivial, since the use of commercial technology ensures high life times and support for spares. Most of our competitors will "fabricate" or cobble together "special" actuators from flimsy components like small stepper motors and DC hobby motors and expect them to service continued use. The sourcing of spares in this case will be required often and will be very difficult.
  • CE Conformance - The CKAS system conforms to the stringent European Standards and Directives for use in the Eurozone. Our system must pass hundreds of tests involving Essential Health and Safety and Machine Design directives, and also comply with Electromagnetic Emission Standards. If you plan to import a competitor system into Europe, which does not conform to CE directives, it will most likely be stopped by your Customs Office.
