6DOF Motion Platform Model

1:10 scaled Fully Functional 6 DOF Motion Platform. Custom made Linux-Realtime software reads the data from FS2004, executes Classical Washout Filter and Drives the servos 50 times per second. Used standard Futabe servo motors.
Classical Washout Filter developed with MATLAB and tuned for Cessna 172.
Next step: Full size platform based on DC geared motors

I do not think you are right. You can check the response of a classical washout filter to learn about the "transmission"

O my God.. u r awesome.. Look at the synchronized moves.. I need to know washout filters working and principles and design. Please help me.I want to design the samething.

Regards!!

farazafzal,

The washout filter is responsible for translating the forces in the airplane to the position of the platform to provide the "same" motion cues.

I use the classical washout filter. It is a set of high and low pass filter. High pass filters are responsible for high frequency (low amplitude) acceleration and angular velocities, and the low pass filters are responsible for low frequency acceleration and the tilt coordination. "GOOGLE" "classical washout filter"

someones hamster will be very happy :3

@ZnEaKySpyNL The model tilting up or down while vehicle is on ground may reflect changes in forward momentum due to acceleration or braking.  Otherwise, in a real person simulator, the body has no means to experience the sustained inertia beyond the range of horizontal motion of the setup. The actual orientation of the model (or simulation vehicle) should be upended by the simulated visual clues to create the VR experience.

Its not realy working right. The model points down when the plane is on the ground the second time. So the transmission has to be adjusted.

A big bravo from me too!

i'm trying to build the same in Labview, but you helped me already a lot.

Thnx!

How you extract information about position in gamespace? And how do you sent this into Matlab?

Which servo controller do you use in this model?

Can I use it with x-simulation software?

[xrey009]

Hello. what software did you use to get the data from FSX and pass it to the servo motors?

thanks
