Cars surprisingly reliable considered it doesn't use any scripts. Ramps though need improvements. First, needs more angle, because ball frequently stuck at gates. Second, i ended up ramp risen while ball out of gates, and vice versa, i suppose you use sensor with rotor->reverse command, but apparently it's not reliable. Suggest use script which will unambiguously rotor rotation direction.

Yes your right. I'm going to try to improve the ramps. Do you have a certain script in mind? More angle will lead to the ball getting stuck between the ramp and the top of the gate but maybe rising the rotor with a piston when folding up will take care of the problem. Thanks for your feedback!

Script will be very easy, something like:
IMyMotorAdvancedStator rotor;
public Program()
{
rotor = GridTerminalSystem.GetBlockWithName("Rotor name") as IMyMotorAdvancedStator;
}

public void Main(string args)
{
if(args == "clockwise")
rotor.Velocity = MathHelper.TwoPi;
else if(args == "counterclockwise")
rotor.Velocity = -MathHelper.TwoPi;
}

Thanks
I think it works now even without the script (by using the on & off command instead of the reverse command). SO the ramps shouldnt get stuck in the risen position. The ball will stay at the gates sometimes but I think thats okay because it is not very hard to get it out. But we'll see.
