    Good afternoon! I am writing via google translate. I want to do 6DoF construction, but for now I decided to start small and do 2dof construction. And so less words, more pictures !!!
    1. Drew the model. No engines yet;)

    1. Sawed plywood and wooden blocks

    3. Cutting aluminum profile
    IMG_20201023_190730.jpg
    4. Bought a thrustmaster T150 steering wheel
    IMG_20201011_205453.jpg
    5. Bought a sports seat (bucket) IMG_20201021_192351.jpg
    6. Bought casters with a stopper IMG_20201023_190852.jpg
    7. Bought a hinge from a car drive and assembled it IMG_20201011_204039.jpg
    8. I am 3D printing various parts IMG_20200930_225954.jpg IMG_20201024_221338.jpg
    9. Collected base IMG_20201024_171122.jpg IMG_20201024_171209.jpg

    Tomorrow I'll go buy bolts and nuts :)
    To be continued: show your teeth

    Nice progress, thanks for sharing your build :thumbs

    What motors and control boards do you plan to use?

    Pre-assembled the structure. With active steering, the rigidity of the structure is not enough IMG_20201025_210530.jpg
    Drew a new reinforced model

    I tried on the hinge on the base

    Assembled a reinforced structure. The construction is rigid and reliable. I'm happy as an elephant :grin. Tomorrow I will assemble a block with pedals and look for the center of gravity.

    What gearbox ratio are you going to use to drive this? The drive point you have chosen will require quite a bit of torque.

    Have a question. Should the red plug be screwed in instead of the screw on top? There is a hole in the plug. What is this for? for the reducer to breathe

    I counted the efforts on the rods. With a torque on the gearbox of 20N * m, the maximum force on the crank is 60 centimeters - 333 N. At the bottom point when moving upwards - 214 N. At the top point, the worst situation is the effort just taking into account two angles 70.4N

    Printed with ABS plastic, 60% filling. I think this will be enough

    Potentiometer coupling. The legs of the green part break faster than the potentiometer. Everything is attached to the gearbox.

    It's small details that add to your design. Very nice.

    Tested cheap drivers for 7 euros. They work very badly:mad:. Change directions for a long time (approximately 0.5-1 seconds). As a result, I burned it and I do not regret it much:)
