Can I use x-sim for any RS485 compatible actuator?

For seat movers DC motors are fine... You don't need much power to move just a seat!

And plus the fact that you don't simulate accelerations anymore... just displacement between the driver and the driving wheel.

It would be true if the seat move along some kind of rails, but it's not. Ok, the position it's not right one, but the seat rotate and tilt like every 2DOF simulator. So it's not just displacement. By the way, some post before I said that the simulator we are designin is a full one, with seat-steering-pedal-shifter all moving, the one in that video it's just a prototype made to understand if I was able to do something like that.

Alright then, think of this... You need a balanced full motion cockpit that can deliver the COG at about your chest height, not the bottom of your seat. Try to imagine it... you will see the difference in the motion cues that each solution provides.

Yes, I know the issue about the pivot height and I tried to made it as higher as I can but there are some limits. I know there is the "tub" solution but it doen't meet the position flexibility that I need. I will run some test when it's done and I will give you my consideration about it.

You know of course that in a 6DOF platform then, its very easy to adjust in software the position of COG anywhere in 3D space!

Yeah, I know dude, but a 6DOF it's too much for my knowledge. I have to take small steps for such a high level project. Maybe one day I will make it!

Actually, from mechanical viewpoint a 6DOF is much easier to build, than any other platform and the only one that can be used for both flight and car racing with changes only in software profiles... All controller and software part is already sorted out, and even a beginner as Richard can build...

At first glance yes, maybe.
If you want to get a "professional" quality manufacturing and a quality end result is not so on ...

must respect the geometry, which is not so simple;
tubes must be welded, we imagine a beautiful frame butt welded with angle cut.
cockpit must not be neglected, we need strength throughout, cockpit simulator / platform.
one can also imagine a frame as Cruden with a high pivot
if the set is not rigid, the movement will be absorbed by the movement of the frame to be linked correctly given to the pilot.


Personally, if I had to make a 6DOF, I would make a simulator with a professional finish, it should be up to these beautiful simulator in terms of quality and finish.
Of course this is my opinion, I'm being too demanding.

[tronicgr]

Trust me, its rigid because of the ball joints. The only backlash you may get is from bad quality gearboxes (0.1mm-0.2mm). Other than that the whole platform is solid.

The geometry don't have to be exact angles etc. The software can be adjusted to fit any dimensions and angles for perfect output.

And of course you want to make it out of metal because of all the forces applied to the platform. Metal frame always have a professional look after you apply some paint on it.

Cheaper to build a 6 DOF, yes, thanks to your efforts.
But if you read the thread from the beginning, this guy is looking for a 2DOF alternative to SCNxxx actuators.
Can we please answer questions related to that?
a 2 DOF seat mover-full frame.
