    My Motion Simulator:
    Arduino
    Hii!! I have been in the community for over a year now. First I carried away with Peacemaker105's 6dof build when I realised that motion sims are something I can challenge myself with. Countless hours of research proved to me that starting with a 6dof would be quite expensive and time consuming (I was studying for university exams back then). Then I lost some interest and focused on studying. After 6 months once more I stumbled upon the community and revived my hobby. But this time I went with something a bit more simple and my biggest inspiration source: @Halloween2go's "Full Frame 2 DOF + Traction Loss new build". Now this design is pretty much the exact replica of his motion simulator. I love modeling with SolidWorks, so I jumped in and started cadding in my free times. FYI I do not know if this design will work 100%, it is a proof of concept for now. That's why I created this thread so that I can get some feedback upon perfecting the design. To be honest, I don't see myself making this motion sim a reality anytime soon, being a student creates a lot of cost issues. But cadding is free and I quite enjoy the time I spend doing it. Now the photos of the design:

    The material I thought about using is 35x35mm aluminum profile because of its low weight and high machinability.

    Pretty happy with the 8.52° up & 7.7° down pitch angles.

    yaw.jpg
    Left & right yaw angles are quite similar with just a 0.11° difference.

    Roll angles are a bit scary, don't know if it is normal or not.

    Traction loss can easily be increased with the length adjustment of the motor arm.

    Even though everything is symmetric there are still angle differences between the opposite positions, could be something related to the assembly I'm not so sure. I'm eager to hear your sights about everything! Thanks for coming all the way down.
