hi,

I wanted to simulate the same mechanism as in “https://www.youtube.com/watch?v=_Z44cmrb-zc” using only inverse kinematics (pure mathematics) with blueprints, and i got really frustrated with rotation stuff (world, relative, local…) and i decided to do that using physics.
in physics i have this problem of controlling objects. like where is the static equilibrium point?
how would you simulate such a mechanism in the video i posted in the link?

i really need some assistance with this

regards

Hello,

You should be able to make that mechanism using physics constraints. I’m not sure how you would control it, though. What do you intend to do with it?

From what I can see, each leg of the platform is made of two ball joints (I think. sorry, I’m not an expert in joints) and a crank. So you should be able to control the cranks with a certain function to make the platform tilt however you like.

Have a look at the crankshaft tutorial, that should help you out a lot.

Not sure what you’re asking about the static equilibrium point. The physics constraints and objects act largely like in the real world. So a simple pendulum, if left free, would point in the direction of the gravity.

Have I answered your questions?
