    I've installed a gaming chair on the platform. Overall, it's not bad. I need to pay attention to the balance, and I also want to make the platform's base lower. The geometry is precise and allows for +/- 15-degree tilt angles. Currently, my main goal is to attach the steering wheel and pedals to the transmission to enable adjustments for both adults and children.

    I'm posting my drawings for the attachment for the Chinese engine from the stroller and the levers for it. I had these drawings laser-cut from 5mm steel. The lever has a length of 70mm, which, with a distance of 250mm from the engine axis to the hinge, allows for a platform movement of +-16 degrees.

    Nicely done :thumbs

    Just something for consideration, the rods being at 90 degrees to the upper rig when level will give the same torque utilisation up and down, while raking the rods as they seem to have been distorts that.

    I reduced the base height by 65mm. I started painting. I'm sharing the rest of my project files. I've included a 3D model of the printed gear, a drawing of the modified angle sensor mount, and a file with holes for the Arduino and H-bridge mounts.

    Over the past few days, I've made changes to the frame's geometry by making it lower, reinforced the hinge points, and painted it. Following the advice, I've adjusted the angle between the platform and the lever to 90 degrees. The travel remains at +-15 degrees, and there's no obstacle preventing the lever from rotating 360 degrees in case of an emergency. In fact, there's even a 1-degree margin. I'm very pleased with the outcome. Currently, I'm working on the pedal and steering wheel attachment with the gearbox. I'm seeking advice on PID tuning. The algorithm of actions.

    PID is an interesting topic, here is a loose explanation that also contains links to far more accurate information, depending on how far down the rabbit hole you wand to go: https://www.xsimulator.net/community/faq/a-laymans-analogy-guide-to-pids-pid-tuning.219/

    The best advice I can offer is to carefully follow the SMC3 setup instructions, check out the explanation of all SMC3 settings in the second post, then run the Sine test and post the result: https://www.xsimulator.net/community/faq/arduino-code-for-use-with-various-hardware-and-simtools.31/
