Optional Control Systems
All motion base platform systems from Servos & Simulation are plug-and-play ready, offering flexible control options to suit a wide range of applications and user preferences.
With several two-axis (2DOF) models available—starting at 500 lbs (227 kg) and scaling upward—each system is designed to operate using a simple ±7.5VDC analog control input, making integration straightforward and versatile.
Included Components
Every motion base platform system includes:
- Integrated electronics in a COTS rack-mount chassis
- Up to 50 feet of interface cabling
- Hubbell 220VAC plug, mating input connector, and generic system manual
- Integrated safety braking system and e-stop integration
- Full system manual (ICD and maintenance) with complete drawing set
- One-year warranty and lifetime email/phone technical support
Computer Control
If the customer chooses to purchase the computer system for motion base control, the package includes:
- Custom Interface Control board
- Input cable
- Operating system
- Keyboard and mouse
- Maintenance software for the motion base
Additionally, for entertainment ride profile playback, the computer can broadcast video while simultaneously controlling the motion base. Customers may specify video card output requirements at contract time (additional cost applies). Systems rated at 8,000 lbs or larger include the computer as a standard component.
Sensoray 826 Card
The Sensoray 826 is our standard interface card, included with the computer control option. It supports:
- ADC and DAC functions
- Digital I/O
- Watchdog capabilities
This card ensures reliable and precise control across all supported motion base platforms.
The customer is more than welcome to choose their interface. Be aware that if you require excellent movement of the system, 16-bit resolution on the DAC output is required. We are here to help with engineering and advice where and when you need it.
Raspberry Pi & Phidgets
Because the system accepts analog signals, it can also be controlled using:
- A Raspberry Pi with a 16-bit DAC installed
- A Phidget card, such as the 1002_0B or OUT1002_0
This option is ideal for home-built flight simulators and supports integration with platforms like Prepar3D, Flight Simulator Steam, and X-Plane. Note: This option is not recommended for larger systems due to limited fidelity.
Measurement Computing Devices
All Measurement Computing ±10VDC analog output devices are compatible with our motion base systems. For optimal performance, we recommend consulting our engineering team to identify the fastest available device to avoid any limitations in motion responsiveness.
Power Requirements
Servos & Simulation’s motion platforms are fully electric and designed to be environmentally green, offering flexible power configurations to suit a variety of operational environments. By default, standard power requirements are 220VAC, though other voltage options are available upon request.
Power Configurations by Platform Size
Smaller Bases
Can be configured to operate on a standard 120-volt, 20-amp circuit using a transformer. Note: The transformer may be supplied by the customer or provided by Servos & Simulation at an additional cost.
Mid-Size Bases (1,000 to 4,000 lbs)
Require 220 volts, available in either single-phase or three-phase configurations.
Large Bases (6,000 lbs and up)
Require 220 to 440 volts, three-phase power.
Additionally, we can wire the system to meet customer-specific electrical requirements, ensuring seamless integration into your facility’s infrastructure.
FAQ
What are 2DOF motion platforms used for?
They are used in entry-level flight simulation, VR and entertainment systems, basic training applications, and demonstration platforms.
Why use a 2DOF system instead of higher DOF?
2DOF systems provide essential motion cues with a simpler design, making them cost-effective and easier to install while still delivering a convincing experience.
How does a 2DOF platform work?
It uses two actuators or pivot mechanisms to tilt the platform in pitch and roll, often leveraging tilt coordination to simulate acceleration.
What are the limitations of a 2DOF system?
2DOF systems cannot simulate full translational motion (surge, sway, heave) and are not suitable for high-fidelity or certification-level simulation.
Can 2DOF systems be customized?
Yes. They can be configured for payload, motion range, and integration with different simulation or entertainment systems.
