    Hi all!
    That's it, I gave in!! With your nonsense, I ended up giving in!
    So here is my simulator currently:

    Reproduced in 3D to bring the mobile part:

    Some reproduction flaws like the steering wheel and the seat ... but I didn't want to bother redesigning them.

    The idea is to raise the frame so that the seat stays at the same height and I don't have to move the rest.
    I would like to do something similar to this, closed with good cooling, so as not to have to dust it everyday:

    It would be mounted on the seat rails in order to move the assembly without shifting the seat CDG.
    2 120w motors are planned, driven by Arduino.


    Some progress!
    I positioned according to Wanegain's tutorial (well if I understood everything correctly ...) and it gives this:

    Then I touched up the back of the chainring because it was hitting the angle iron on which the motor is fixed in case the latter decides to make a full revolution:

    Do specialists see errors or am I on the right way?

    Have a play with SimCalc, that will help you get your head around design Vs physics tradeoffs: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    Turning the levers to face the opposite way and moving the connection point out as far as possible on the top frame would help.

    In a compact design torque is more important that lever linear speed. Personally I use 200W motors with 60:1 wormdrives on my compact rig, and have maximised the inherent leverage as much as possible within the confines of its small footprint.

    Oh... I sould be more serious at school with mechanic lessons... :(:D
    I don't really understand the answers...

    Yes of course!
    I began with this setup. I builded with tube and sheetmetal with a Peugeot 306's seat. It had to be compact on wheels.

    Later I changed my setup and did a frame with wood. I also modified a handbrake from AE and builded a SQ shifter.

    Today i have the same setup, with improved SQ shifter, mod on my CSPV1 (spring and elastomere), and mod on may shifter inspired on upscaliber.

    And now it's time to move my ass with a seat mover!

    Looks really good. You can improve motion with so many posted builds. You are gifted with home built simulator. Spend the time searching and reading many projects.

    Some advancements! The mechanics are not easy !! Fortunately, there are specialists to help out!

    Here is an animation with the maximum operating angles, then to finish a full turn to check for possible collisions.
