The drawbot is dually equipped with markers for a smooth drawing experience. It makes two different sized circles, because it has the two markers.


1. Styrofoam cup

2. Blue and yellow Crayola markers

3. Electric toothbrush


First, I punched a hole in the back of the styrofoam cup. Then, I inserted the electric toothbrush into the freshly made hole. I the repeated this process in the sides of the cup, and proceeded to insert the two markers.
