Drawing bots make beautiful designs. Every Bot is different and the possibilities are endless, so it's important to experiment! For some inspiration check out the generative art workshops littleBits ran with AIGA
Circuit: All of our art Bots are made with very simple circuits. Start by connecting either power + vibration motor or power + DC motor. To control the speed and frequency of your art bot try adding a pulse (For example power + pulse + vibration motor)
Art Materials: This is where you can experiment with all different types of drawing materials: paint, chalk, markers, crayons, you name it! For our art bots we decided to use chalk. -Rubber band a piece of chalk around the small metal part of the vibration motor. As it vibrates the chalk will make quick random marks all over your paper. -Attach a wheel to the shaft of the DC motor (We used a laser cut wheel specially designed to fit with the motor. You can find the file for the wheel on this page "wheel template"). The angle at which you attach the chalk to the wheel will effect the type of mark the chalk makes, so have fun and experiment!
-Don't have access to a laser cut wheel? No worries. You can easily create your own wheel from all sorts of different materials. We made a basic art bot by cutting a circular shape from a piece of cardboard. Then we poked the shaft of the DC motor through the center of the cardboard and used some glue to keep it in place. Cut some slits in the cardboard to slide the pipe cleaner through and tie the pipe cleaner to the chalk. Anyone can make an art bot!
Now it's time to start drawing on dad! Draw an outline of your dad (Or use the one we made "Dad Drawing Template"), place the art bots down on the paper, and watch them go to work!
