The Heart of Ultra-Precise Motion: ARK Dynamics' 21-Bit Encoder Revolution

At ARK Dynamics, precision isn't just a goal—it's our foundation. Our revolutionary 21-bit encoders represent a quantum leap beyond industry standards, delivering positional accuracy that transforms what's possible in motion simulation.

Beyond Industry Standards: The ARK Advantage

While most motion platforms rely on standard 14-bit resolution, ARK Dynamics surpasses this limitation with 21-bit encoders that deliver exceptional position control. This isn't just an incremental improvement—it's a paradigm shift that unlocks entirely new levels of fidelity in motion simulation.

Unprecedented Resolution: A New Era of Accuracy

Our 21-bit encoders capture over 2 million distinct positions, tracking every micro-movement down to the finest degree. To put this in perspective:

• 14-bit systems: 16,384 positions per revolution

• 21-bit ARK systems: 2,097,152 positions per revolution

  
  

This 128x increase in resolution means movements that were previously invisible to motion platforms are now captured with surgical precision.

Micron-Level Accuracy: The Details Matter

The 21-bit encoders ensure micron-level precision, enabling applications that demand absolute accuracy. Whether you're simulating the subtle vibrations of a race car's engine or the precise movements required for surgical training, every nuance is faithfully reproduced.

Real-Time Performance: Speed Meets Precision

Precision means nothing without speed. Our 21-bit encoders track every micro-movement at 400 Hz updates—faster than the human eye can perceive. This real-time feedback loop ensures that complex motion algorithms can respond instantly to changing conditions, maintaining perfect synchronization between virtual and physical worlds.

Six Degrees of Perfect Freedom: Unleashing Potential

Six independent actuators drive the platform, enabling full freedom across surge (forward/back), sway (left/right), heave (up/down), pitch (tilt forward/back), roll (tilt side-to-side), and yaw (rotate left/right). Each axis benefits from the same 21-bit precision, ensuring balanced and accurate motion across all degrees of freedom.

Direct-Drive Advantage: The Power of Simplicity

Unlike belt- or gear-driven systems, the Portal's direct-drive design eliminates lag and wear, delivering instant torque and smooth motion. The 21-bit encoders work in perfect harmony with this direct-drive architecture, providing immediate feedback without the mechanical backlash and wear that plague traditional systems.

Advanced Control Integration: Seamless Motion

Our controllers with Field Oriented Control (FOC) work seamlessly with the 21-bit encoders to provide smooth, accurate motion simulation. This sophisticated control system leverages every bit of the encoder's precision to deliver motion that feels natural and responsive.

Performance Specifications: The Numbers Speak

• Resolution: 21-bit (2,097,152 positions per revolution)

• Update Rate: 400 Hz across all 6 degrees of freedom

• Linear Motion: Up to 1300 mm/s with precise position feedback

• Angular Motion: Up to 190 deg/s with continuous position tracking

• Acceleration: Up to 3G with maintained positional accuracy
