Use The Pen Attachment In The Simulator

The Micromelon Robot Simulator comes with a range of simulated Rover attachments. You can toggle the simulator rover attachment from the in-activity menu in the top left.

How To Program The Pen Attachment

Once we add the pen attachment to the Rover we are able to control whether the pen point is making contact with the ground by raising it or lowing it with the server blocks.

Lowering The Pen

To lower the pen attachment we the servo motor connected to the attachment to -90 degrees. This will move the arm down. If your pen does not make contact with the ground, you should adjust the pen in the pen holder so it does.

Raising The Pen

If you do not want to draw you can raise the pen. Set the servo motor connected to the attachment to 0 degrees. This will move the arm up.
