Controlling the original GS-4 and DIY G-Seats with SimTools

While the GS-4 is no longer sold it remains the pinnacle of tactile style motion simulation.

Fortunately for GS-4 0wners @darkcrayon has established how to interface the GS-4 with SimTools and provides the code to do so: http://www.xsimulator.net/community/threads/simtools-and-simxperience-gs-4.7050/#post-82352

Simtools 2.4 setup to prevent negative vales and movement

► simtools
To prevent negative vales and movement take @yobuddy's advice and use SimTools v2.4, then allocate a '0' for the min value in Sway and Roll.

This basically turns off the negative inputs for this DOF

We should be able to do this without modified plugins like this. :cheers

First Game Engine needs to be in "Expert" mode, this gives us separate Min/Max files for both (a) and (b) Axis Assignments.
Then setup you axis assignments like this.

Notice this is the - (a) Axis Assignments.
[IMG]

Notice this is the - (b) Axis Assignments.
[IMG]

Then in Tuning Center, make sure both sets of Min/Max settings for (a) & (b) Axis assignments are the same, except for sway.
For (a) Axis Assignment use a sway like this.
[IMG]

And for (b) Axis Assignments use a sway like this.
[IMG]

What you have essentially done here is turn off sway in one direction for each axis (the 0 turns them off in that direction.)
Now all you have to do is change your interface output.
Wherever you are using <Axis2a> Change it to <Axis2b>.

With this example above, all game plugins should be usable without modification.
If anything in the example needs more explaining, let me know!
Take care, :thumbs

yobuddy

►in your code:

We're sending 8 bits to Arduino as per interface settings, so that means values between 0 and 255. 0-127 is -ve and 128-255 is positive (heave/surge)

I can't do -ve DOF so I have this line that clips anything 0-127 and 128 is minimum

if (actuatorPosition[currentActuator]<128) actuatorPosition[currentActuator]=128;

So now the values are 128-255 and these are mapped to the values which go to the servo as per below. These numbers vary servo by servo and with ASMC/E you even need to tweak for individual servos depending on how the tiny pots might have been adjusted for sensitivity.

***** RC servo Code for Arduino UNO - 2DOF - Expandable 2.0: by eaorobbie
http://www.xsimulator.net/community/marketplace/rc-model-code-for-arduino-uno-2dof-expandable.89/
https://www.xsimulator.net/community/threads/rc-model-for-motion-simulation.4600/
interface setup - IMPORTANT - Assuming a 2DOF for SimTools 2 the Interface Output should be set like this R<Axis1a>~L<Axis2a>~

and for expanding code to use more servo http://www.xsimulator.net/community/threads/my-project-guide-me.5682/#post-59262
To add servos to my code , for example to include 4DOF with my code

Line 9 - How many Servos to use.
const int kActuatorCount = 4;

Line 13 - The Identifier used for Servo
const char kActuatorName[kActuatorCount] = { 'R', 'L' , 'F', 'B' };

Line 14 - Where is Servo is connected
const int kPins[kActuatorCount] = {3, 5, 6, 9};

Line 15 - 17 - Sets the scaleing in degrees of movement used , this is set for 180 deg if counting from 0
const int kActuatorScale[kActuatorCount][2] = { { 0, 179 } , // Right Actuator scaling
{ 179, 0 } , // Left side Actuator scaling
{ 179, 0 } , // Front side Actuator scaling
{ 179, 0 } }; // Back side Actuator scaling

Line 21 - Sets the Initial position of servo when in starts in Degree's
int actuatorPosition[kActuatorCount] = {90, 90, 90, 90};

Note in lines 15-17 if servo moves the wrong direction you can simply invert them by changing the scaling.

gHead gHelmet gSkull DIY systems

► here is a functionnal gHead bowden cable system made by sberns!

► here a bladder gHead system by @Banfy
Having your head being moved by an external device feels really like having a helmet with G-Force.
Finally i have just put a bladder behind my head, under the seat cover (red spot) and it give quite good results considering how simple it is to implement ;-)

I can set it either for breaking or accelerating. I prefer the acceleration mode (simulating the helmet being compressed to the seat)

► concept from @BlazinH
https://www.xsimulator.net/community/threads/jiffy-g-seat-and-g-skull.14052/
I use springs also but it appears for a different reason. I use torque only motor drivers therefore when a force ceases there is not a return to what would be considered neutral position because positional feedback is not present. In real life your head naturally snaps back to a position that feels natural and that's how my system works too. However there is some inherent resistance to movement in my actuators drivetrains so I use springs to provide just enough counterforce so your head doesn't feel a resistance when righting itself.
