I am trying to move my servos for my head on my robot. I read that I have to release the servos before allowing them to move. I did exactly that and nothing appears to happen. I played with the position and speed and it still does not work. The robot is laid out like a Roli without the arms. THe servos are the ones for the neck. I am wondering if there is anything I did not see or failed to see.

Code:

using System;
using EZ_B;
  
public class HelloWorld {

    static EZB _ezb;

    public static void Main() {

        _ezb = new EZB("Test");

        Console.WriteLine("Connecting to EZ-B v4...");

        _ezb.Connect("192.168.1.1");

        if (!_ezb.IsConnected) {

            Console.WriteLine("Unable to connect to EZ-B v4");

            return;
        }
else{
_ezb.Servo.SetServoPosition(EZ_B.Servo.ServoPortEnum.D9, Servo.SERVO_CENTER);
}


        Console.WriteLine("Hello World, I am moving servo d0 to position 90!");

        _ezb.Servo.ReleaseAllServos();
	_ezb.Servo.SetServoPosition(Servo.ServoPortEnum.D9, 140);
 	 _ezb.Servo.ReleaseAllServos();
	
	Console.WriteLine(_ezb.Servo.IsServoReleased(Servo.ServoPortEnum.D9));
Console.WriteLine(_ezb.Servo.GetServoPosition(Servo.ServoPortEnum.D9));
Console.WriteLine(_ezb.HC_SR04.GetValue(Digital.DigitalPortEnum.D21,Digital.DigitalPortEnum.D22));
_ezb.Movement.MovementType=EZ_B.Movement.MovementTypeEnum.HBridge;
_ezb.Movement.HBridgeLeftWheelTriggerA=EZ_B.Digital.DigitalPortEnum.D1;

_ezb.Movement.HBridgeLeftWheelTriggerB=EZ_B.Digital.DigitalPortEnum.D2;
_ezb.Movement.HBridgeRightWheelTriggerA=EZ_B.Digital.DigitalPortEnum.D3;

_ezb.Movement.HBridgeRightWheelTriggerA=EZ_B.Digital.DigitalPortEnum.D4;
_ezb.Movement.GoForward(254);
    
	
    }
}
