I am an electronic engineer that loves art and mechanical systems, so Painter Bots are the ideal way of getting involved with both. As I am not part of a university or research group most of the ‘development’ happens after hours when the kids (and wife) are in bed. The robot I am entering is called Sonmi-231. She follows 2 basic paint behaviors. 1) When she is close to a boundary of a shape she will follow it until she reach an area in front of her that has already been painted or she moves to fast to follow a boundary wall that moves away from her. 2) She will paint straight ahead but will move to the left or right if the area in front of her has already been painted. At the moment she has no feedback from sensors or cameras so the mixing of colors is not accurate. For most of the paintings the colors are mixed before paint is applied to the canvas, but I have also experimented by painting color layers straight onto the canvas. Most of the development was done in Processing, with some scripted image processing through GIMP and Potrace. The hardware is a simple XYZ axis painter bot that use a GRBL controller to process gcode send to it either in real time or from a file. For more information:
