Showroom DIY 3 DOF motion simulator (2dof axis with Traction loss)

HI everyone, i will remake my motion simulator and turn it from 2dof to 3dof, and this time i will make it step by step to make it as perfect i can.


1. First of all i need to get the best center of gravity because before i made a mistake by randomly Put the cvt joint and weld it like its wont affect, but after all i relized that its so important for making the motion smooth and reduce motor power given.

Because i have a recommended motor but ita struggle with movment so now i need to know exactly what should i choose between this 2 draw.



In number 1 : the rig when finding the COG the front point touch the floor and the back in the air. But one i move my self a little front and back i can move the rig with good power so i can move front and back with diffrent amount of power.

In number 2 : the Full rig balanced on air but any small movment like move myself back its easly move back but to return to middle point or to front i need power to move it but to back and front like same power but need more power than number 1.


My thought : i think number 2 make since of balance of gravity meaning, but number 1 can move forward and backward with likely same power.

I watch this tutorial but i cant see if its like number 1 or 2. And did it need just to make sure its only same height in both side dosen't matter how much power i need to move it like just balanced?
