this is my drawing robot. it uses a Sharpie to draw. using a sharpie is way more convenient than using a paintbrush.1) more precise. 2)easy to change colours 3) less mess 4) no need to wash wheels after drawing 5) easy to stop robot from drawing.
this is the end product. not all that neat, but still far neater than anything with paint
here is the robot. like the way i hold the sharpie?
This is the programming for the robot. I had it compressed into a Single Block, but extended it so you could see
