DK DNA

Sigma Advantage

Mechanical

All DK motion systems are made in USA from a solid piece aluminum for optimal strength, durability and to best translate haptic feedback and motion. Machining from billet aluminum is significantly stronger over other methods of production such as casting, bolted assemblies or 3D printing. Each system also features a solid 2” steel piston and oversized ball screws for optimal smooth performance and long service life with no maintenance intervals required. Our unique fully integrated foot design installs in less than 30 minutes with our own billet aluminum brackets.

Sigma Advantage

Electrical

Sigma uses premium American-made Teknic integrated motors specifically tuned to run Sigma’s advanced motion algorithms. At double the price of conventional motors, the servos have 3x the performance and are the only ones in the industry to operate at a 75VDC to reach Sigma’s internal performance standards. Each motor is also optically isolated guaranteeing zero electrical magnetic interference or EMI. Cable lengths from the controller to the motors can go up to 150-feet and the controller connects via an ethernet cable to the computer for optimal signal integrity. The controller is switchable between 120/240v and ships region specific power cables and accessories.

Sigma Advantage

Software

Sigma takes a first principles approach with our motion software and algorithms. Hence, we build and develop all our embedded and motion software in-house. This allows Sigma to achieve absolute performance and control of its mechanical and electrical integration. Our software features specialized motion layers and unique algorithms to achieve what we call Motion Integrity™ or the most accurate representation of simulated motion. Pitch, roll, heave, environment, and our True Haptic™ engine and road vibrations are some of the best in the industry. Our software also installs quickly and has automatic over-the-air software and firmware updates. Remote tuning and control of the system is convenient and can be done in real-time with our remote software without having to switch between software.

Our Motion Algorithms

  • Velocity Trap™ Algorithm


    Our base algorithm and unique to Sigma that provides for a smooth and natural motion representation. Available to all
    DK motion systems.

  • Dynamic Scaling™ Algorithm


    This algorithm allows for the full use of the actuators available stroke. Allowing all the motion layers to be intelligently represented at the same time.

  • True Haptics™ Algorithm


    Sigma's first principles approach to high frequency vibrations. Our unique approach to haptics means no canned effects, just pure signal reconstruction.
