I have a rotating part, when it reaches a certain point in it's rotation it makes contact with a static part, and should then stop at which point it will reverse direction until it reaches the static part again.

In the assembly how do I set it up so that the part doesn't rotate 360 degrees and just keep going "through" the other parts?

Could somebody help me out with collision detection and how to make this thing stop when it contacts another part in the assembly?
