    Hi there! I'm from China and I'm currently replicating @knaufinator's 6DOF-Rotary-Stewart project: https://www.xsimulator.net/community/threads/compact-ac-servo-6dof-rotary-stewart-platform.14769/

    I've managed to source the hardware locally at a very low cost: the AC servo motors are about $28 each, and the 50:1 planetary gearboxes are just $11. These are high-quality second-hand teardown parts from industrial automation lines, which is why the price is so competitive. The ESP32 controller build came in at around $10 as well. Really excited to get this rig moving!"

    Sorry, I can't send you the link. If you need a brand-new one, you can buy it on Taobao. Don't buy it on AliExpress, because many sellers there mark up the price.

    If you want the same industrial used parts, you can buy them on the Xianyu app — it's a second-hand trading platform with great cost-performance. You just need to look for items where you only pay for the shipping fee, and you can get very cost-effective products.
