Unique Features of all DK Systems

  • American made motion system with premium support and components.
  • Billet aluminum and steel design for incredible strength and haptic feedback.
  • Nickel plated solid steel pistons for ultimate strength, quiet operation and durability.
  • Industry only 75 VDC power architecture with custom cable length options.
  • American made Teknic motors tuned and tested to work with our DK actuators.
  • Advanced motion algorithms controlling speed, acceleration and jerk in real-time.
  • Any DK motion system combination can be upgraded at anytime into the future.
  • Software only gets better over time with continual over-the-air software updates.

Mechanical Engineering

The Billet Difference

All DK motion systems are made in the USA from a solid piece aluminum for optimal strength, durability and the best haptic feedback.

This processes is significantly stronger over other competing methods. Each DK features a solid 2” OD steel piston and oversized ball screws for optimal smooth performance and long service life with no maintenance required.

The DK system installs in less than 30 minutes to almost any aluminum extrusion with the included aluminum brackets.

ELECTRICAL ENGINEERING

High Voltage Design

Sigma uses only premium American motors and are the only company that offers a 75-volt DC architecture. The higher voltages allow for thinner cables and powerful but compact motor design.

Our advanced motion algorithms are processed in real-time by by a Cortex ARM 32-bit processor inside our custom controller (the size of a few stacked laptops).

The system runs on various voltages around the world and connects via network cable to your computer for optimal performance over standard USB.

SOFTWARE ENGINEERING

Unique Algorithms

Sigma takes a first principles approach with our motion software and algorithms. We design, build and develop all our embedded and motion software in-house.

Our software features specialized motion layers and unique algorithms to achieve what we call Motion Integrity or the most accurate and PURE motion simulation without the use of triggered effects.

Our software is easy to use and is constantly getting better with over-the-air software updates. The software is specifically tuned to work with our electrical and mechanical systems to provide a simple turn-key experience.

Pure Algorithms no Effects or Gimmicks

  • Velocity Trap Algorithm


    Our base motion algorithm is unique to Sigma and provides 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 of the motion layers to be intelligently represented at all times.

  • True Haptics Algorithm


    Our first principles approach to high frequency vibrations with no canned effects. Focusing on pure signal which results in less tunning and more driving.
