    Good day or night to everyone. Who works :). He began to build a car simulator, a new topic for me, but there is no place to see and try. Maybe someone will advise or correct something if something is wrong. I will say right away that I am not strong in programming, or rather not at all. I looked through a lot of things and settled on the construction (motion-sim.cz) though with its reconstructions. I took the steering wheel, pedals and gearbox controller from (MMOs ForceFeedback), tried it, it works pretty well (there is nothing to compare with). Steering engine set at 4 Nm DC, Encoder 5000 imp.ob. In principle, not enough. With recoil and effort of rotation, everything is fine, and the end stop of the steering wheel is small, you can scroll with great effort. I think we need to set AC Servo (synchronizer) to 7 Nm. The pedals are still under development. The gearbox was taken by Fanatec ClubSport (It makes no sense to do it yourself, the price and quality are adequate). I decided to do linear pushers myself. The decent Chinese cost $ 1,100 + shipping. Making it yourself is half cheaper, if you do not take into account the development time. And this turned out to be not at all simple, but there could be no return; servos and ballscrews were purchased. At the moment, the project is ready, I’m cutting a piece of iron. Servos using AC 4Nm, 1Kw, 3000rpm. Ball screw 16mm. 10mm pitch. Gear ratio 1: 1 (10mm rod stroke per engine rev.) From the video I want to use HTC ViarPro, the image quality is certainly worse than on the monitor, but more real. So far only the frame is ready, everything is in the process of searching. If someone writes some of their thoughts, I will be grateful.

    Hello. I myself developed a motion pusher. I’ll post a photo later.
