RC Model for Motion Simulation

Servos also use potentiometer to calculate position.

@Jun if that is the case than how come @eaorobbie's circuit on first page does not have anything going to analog input on arduino? Unless the servo has its own feedback loop?

Here is a simple explanation how-servo-motors-work

Cheers

Thanks @Jun

this is my model for three axis..roll yaw and pitch...how can i got the coding using arduino ?

As a simpleton with general knowledge and understanding of the world, how can I possibly follow this? I successfully set up your 2dof system with hobby servo's running LFS, seems quite nice, however now I want to get into the reason I am here which is a 5 dof system where a 6th component is an electric motor offering 360 degree continuous yaw. Do you think I can do it or am I dreaming?

I followed your instructions earobbie on how to expand the 2dof to a 4 dof but it didn't work. I simply copied and pasted the code into arduino for the 2dof setup, (thanks so much for that), I wish I could do the same for a 6dof setup. (hint hint). No seriously, I tried to change the parts of the script you suggest but still no luck.

Yes, absolutely. The thing I don't understand is that I have seen a screenshot of the interface setup where the Interface output is R<Axis1>~L<Axis2>~F<~Axis3>~ etc, however in other posts it says you must specify a number from 1-255. what is the difference?

Oh well thank you for making this understandable. So I guess an example would be when you have a high sitting seat, you might want it to drop down low at the end? Wonderful to know and thanks.

Sending that via the axis output will cause code to error:

R<Axis1>~L<Axis2>~F<Axis3>~ is correct you had a "~" in the wrong place

Code reads the letter R , L , or F as you have set to decide which servo to move. Then reads <Axis(x)> value which is 8bit meaning it has a range of 0-254 being 127 is horizontal. Depending on how you have set the scaling in code it will either have 0 or 254 as it top position or the opposite on the bottom position.

Hope that helps a little.

Stickied so new users can find this easier. It is a great tool for prototyping new builds, especially for new users. I know it helped me a great deal way back when.

Nice!!
Thanks to your project.

excelent!, i wonder if i can use two servo motors or another king of motor to built a force feedback system to my steering wheel, because it does not have any.
my idea is use sim tools for simulate the forces in the wheel.

Thank You!, first i spend 10 coins download code but i didn't know how works exactly but then i download the full package with the presets and works perfectly. i dont have servo but i connected two leds and i can see the change in the light.

I bought a servo motor and drive plate, but no SimTools GameEngine like are not gold, and now really want to try the effect, how do ah brothers

I remember my first test was with a couple of lego Motors, with a rig made of lego and a Scalextric Audi R8 sat on top.
I have a video somewhere of the first run. will have to dig it out.

I seem to have trouble getting any noticeable movement from my servos. Sketch is running with no errors, wiring is correct, but the only thing I am unsure about is the Axis Assignments and the Interface settings.
