But let’s talk about the lack of maps. This is not “missing” in the sense that it should be there but we haven’t gotten around to it. It is explicitly absent from the project at a conceptual level. It’s not a bug, it’s a feature. I touch on this briefly in our FAQ page, but my answer is not much of an explanation. A full explanation would mean a long discussion about graffiti abatement and enforcement, but the short answer is: I won’t tell you because that information is private.
The robo-rainbow, as it is called, takes only a few minutes to setup and is attached to a bicycle for mobility. Then when the target wall is found, the bike is parked next to the wall and a cordless drill supplies power to a lifting arm while electronic actuators depress the sprayers on six different colored spray paint cans. Sure this isn’t the Mona Lisa we are talking about here, but this rainbow graffiti certainly beats the heck out of the gang tags you normally find in urban landscapes.
There’s not much to explain that can’t be gleaned from watching the hypnotic video, a piece of production as beautiful as the robot itself. Powered by a cordless drill, the torque is transferred to a counterweighted arm which lifts six paint spray-cans in an arc.

[mudlevel] built this rainbow graffiti producing robot for an art exhibit in San Diego. While there are no build details we can easily pick this apart from the pictures. Looks like the brains are an arduino, the drive is a power drill with the trigger removed, and a few other servos for firing the spray cans. The counter weighted arm for creating the rainbow was a pretty good idea too. Watching this, we had an idea for a super simple purely mechanical way to do this that would be similar to a catapult. You could use the motion of the trailer to “wind up” the counter balance with a simple ratcheting spool of string attached to the axle. Engage your spray cans and let the balance drop and you’re done. Pedal on to re-wind the counterbalance for another rainbow.
