I want to simulate a Thymio 2 drawing sewing patterns on fabric. So I created a world and implemented the behavior of the robot. Then I added a Thymio2Pen to the bodySlot but the pen didn't draw at all. The robot did however drive how it is supposed to. I then created a different, very simple world with only the Thymio, the Thymio2Pen and a default floor and added a controller which set both motor velocities to 5. And again the robot did drive but it didn't draw.
So now I don't know why the pen isn't working. Maybe someone has had the same problem or knows why the pen doesn't draw.
