Drawbot is a drawing system that anyone can use without having to learn electronics. It is a simple bot that mixes standard drawing materials (in this case magic markers) with weighted motors and plastic cups. When the cups vibrate, they draw circles and lines depending on their overall weight and power. The project teaches programming to kids through physical means or “Physical Programming”. By adjusting the weight distribution of materials in the cups, the bots draw different patterns on the paper and are thus changed through simple forms of augmentation.
I have been running workshops teaching kids and adults to build Drawbot robots since 2003.
