Light Painting Robot

I created this robot to help with light painting techniques. If you don’t know what light painting is, this link ( gives a general description or you can simply google “light painting images.” I wanted this robot to have preprogrammed functions to move in certain shapes. For example, if I wanted to create a circle, I would simply rotate the bot 360 degrees. I wanted to make this more complex, so I used a single led (for now) to create the light source. Based on the movement of the servos and motors, I can create any shape I want based on mathematical functions. Now, if I wanted to use the bot for anything else I can also manually control it.”
