Outer space simple vehicle controller

[itzikpel]

Hi,

I am a little struggled to build a controller that I think should be pretty simple. I have a curvy path and I need to move a vehicle along the path.

The path is in outer space, so there is no gravity and the vehicle need to be sticked/magnetized to the path.

But there is obstacles along the path like bumps and ramps that need to physically accurate affect only the local Y position and local X rotation of the vehicle.

Any suggestion how to implement a controller like that?

Thanks.
