I have attached the dll that you can use directly in GC as well as the sample dgn file and the arduino file for two servo motors.

You need to first load the assembly, such as follows:

transaction script 'Add assemblies'

{

    AddAssemblySearchDirectory("D:\\flo\\MyC#\\UbiMash_v3.0\\src\\UpdateServo\\bin\\Release");       --> PLEASE CHANGE THIS TO THE LOCATION OF THE DLL IN YOUR COMPUTER AND DON'T FORGET THE \\ DOUBLE SLASH

    LoadAssembly("UpdateServo.dll");

}

Then add graph variables:

transaction graphChange 'Add graphVars servos'

{

    feature User.Objects.servo1angle Bentley.GC.Features.GraphVariable

    {

        Value                     = 45;

        LimitValueToRange         = true;

        RangeMaximum              = 180;

    }

    feature User.Objects.servo2angle Bentley.GC.Features.GraphVariable

    {

        Value                     = 10;

        LimitValueToRange         = true;

        RangeMaximum              = 180;

    }

}

Then add the feature UpdateServo:

transaction graphChange 'Add updateServo01'

{

    feature User.Objects.updateServo01 Bentley.GC.Features.UpdateServo

    {

        cs                        = baseCS;

        PortName                  = "COM18";   --> THE VALUE OF YOUR SERIAL PORT NAME CONNECTED TO ARDUINO

        servoAngle                = servo1angle; --> NAME OF THE GRAPH VARIABLE

        servoNo                   = 1; --> STARTS FROM 1, THE SEQUENCE NUMBERING OF YOUR SERVO

    }

}

transaction graphChange 'Add updateServo02'

{

    feature User.Objects.updateServo02 Bentley.GC.Features.UpdateServo

    {

        cs                        = baseCS;

        PortName                  = "COM18";

        servoAngle                = servo2angle;

        servoNo                   = 2;

    }

}

Modify the graph variables and see the reactions of the servo

transaction graphChange 'Change servo1angle'

{

    feature User.Objects.servo1angle Bentley.GC.Features.GraphVariable

    {

        Value                     = 169;

    }

}

transaction graphChange 'Change servo2angle'

{

    feature User.Objects.servo2angle Bentley.GC.Features.GraphVariable

    {

        Value                     = 130;

    }

}

The arduino pde is attached. And you can modify it as required. Note that I use pin no 9 for servo no 1, pin 10 for servo 2, and so on. And you need to change the variables of the number of servo. This is defined in the .pde

#define ROBOT_COUNT  2

#define FIRST_ROBOT_PIN 9

Hope it's useful. Let me know how it goes.

Cheers,

Flora

wow, fantastic, thanks! I'll try to give it a go this weekend... I am
building robotic arm for drawing curvilinear geometry, I hope this can work
smoothly with 3 servos instead of two.
cheers!

if you're using the cheap servo's I alway s use, you might want to give them a bit of slack, instead of driving them to 0 or 180, use 2 and 178 as the boundaries...

You can easily change it to 3 servos by modifying the COUNT variable in the arduino pde.
