    Hi guys,
    I'm starting to design my first 2DOF DIY simulator. Everything is based on these 2 wiper motors from an old car.

    I will use an Arduino UNO with the SMC3 firmware to drive them.
    The project is to create a RIG that simulates the cockpit of an F1 car.
    The RIG will be attached at the rear with a gimbal and on the front will be placed the 2 motors that will allow simulating the various forces of the car.

    I started to design in Fusion 360 the simulator cockpit. Soon I will post some renderings.

    I will continue to keep this thread updated to show my progress.

    If I put the wiper motor over the wood, do I still need to ground it?

    Yes as you need to electrically ground isolate the wiper motors, rather than just mount them on low conductive material.

    UPDATE 23/11/2021

    Hi everyone,
    I tested the motors today to see if the external chassis was grounded, but it's not, so I think I'm fine from that point of view.

    Regarding the power of the motors, I was thinking about a design with the universal joint placed in the center of gravity of the rig and the two motors in the front, theoretically, it should work.

    Here's a drawing of my idea

    I'm waiting for your advice...

    Thank you all for your answers and interactions with my project.

    Oh, I forgot to mention that I ordered the drivers for the motors and I'm waiting for them to arrive in the mail so I can start testing.
    In the meantime, I will continue to design the rig and maybe even build it.
