DIY 2 DOF +Traction loss motion simulator With Wiper motors – VN

in this post I will put all the steps for building a cheap do-it-yourself simulator.
Day 1:
Shopping
1. Arduino x 1
2. BTS7960 x 3
3. Jack GX16 5pin x 4
4. Wiper motor x 3
5. cardan joint x1
6. power supply 12v 30a
7. pully
Puly GT2 20 teeth diameter 8mm X 2
Puly GT2 50 teeth diameter 10mm X2
GT2-2M Timing Belt – 148 x2
8. Ball Bearing p000 10mm x 4
9. Oscillating Rose Ball Joint Bearing x 6pcs
10. Square Steel Tube 25 X25 : 3 pcs
Day 2-4: design and Soldering frame
Firstly, I weld the frame, the steering wheel stand, the gear stick, and the pedal.​

This is the result

Next, I weld the frame for mounting the engine and the cardan joint. To find its center of gravity, I use a roller as shown in the picture. Then I sit on it and find the balance position.
​

Similar to engine mount brackets, I use a V-shaped steel bar to make POT mount.

I am using two ball bearing mounts to create a pivot point for the arm, reducing the compression force on the motor shaft while also allowing for easy connection to the POT through the pulley.

This is the result
​

I plan to make a frame for simulating Traction loss, but I might do that later. Next, I will connect the Arduino with IBT2.
Day 5-6 : design Box and connect Arduino with IBT -2
I am using a GX16-5 pin jack to connect the POT, motor, IBT2, and Arduino. GX16-4 pin to connect the power

I am putting it all in a box, adding a fan from a CPU power source. I got a pretty nice looking box.

Day 7
I am testing the connection to SimTools and adjusting the data, and I will send a video test when it is finished.
I will keep you posted about the progress.......

Day 8-9: Constructing a Frame for Simulating Traction Loss
After testing the simulation and response of the left and right motors in the LFS game, I continued to weld the frame for the third motor's simulation part.

​

I plan for the shifting mechanism to move about 10 cm to each side, so I will weld a trapezoidal frame as shown in the picture. At the midpoint of the smaller base of the trapezoid, I weld a vertical axis perpendicular to a bearing pillow to attach to the upper frame, creating a rotary motion.

​

At the larger base, I weld an additional horizontal bar corresponding to the center of gravity of the simulation seat. It is a sliding bar for the wheels on top to lean on.

.​

Next, I install the motor and determine the position of the lever arm attachment point.

​

The result after two days of work is:

​

At this point, the basic mechanical simulation part is done, everything seems fine, I will paint it and upload its picture when it's finished. I owe you a video, I will soon upload it when I find a "guinea pig" to sit on it for me to film. See you later..."

After waiting for many days for the "guinea pig" to shoot the video so that I can show everyone my achievement!

Thank you, admin @yobuddy @noorbeast #everyone for helping me complete this project.

Thank you for your advice. Now, I am facing an issue with using simtools v3 when connecting dual computers. In this version, I cannot find where to set the IP. Can you help me, noorbeas?

Thank @yobuddy for explaining SimTools v3 to me in more detail. Currently, I am facing an issue, and I would appreciate your help in analyzing it.
When I connect my Logitech G27 steering wheel and Arduino simulator to my PC, everything works fine. However, when I power up the IBT2, the USB ports of both devices disconnect from each other. My proposed solution is to use dual PCs, with each device connected to a separate PC, which works perfectly. I suspect that the issue may be caused by the power supply I am using, as I am using one power supply for all three IBT2s. Another possibility is electromagnetic interference from the wiper motor, as this issue occurs when the motor is powered on. With your extensive knowledge in this field, could you provide me with some possible explanations?
