Turn your Ozobot Bit into a drawing turtle! Discover your robotic artist within!.
This is designed to fit snugly over the helmet or the decorative skin. It will hold a standard felt tip pen. I have tested it with the a few different varieties of thin barrel (10mm) pens.
I have adjusted the pen to sit alongside the wheels to allow it to pivot around the pen. There is an example script that will draw the hexagon (pictured above) on Ozoblockly code rgmccr link:
