Graffiti takes time whether you’re an amateur or a seasoned expert. This crazy robot lets you sit back with a cold beer while it goes at the work of tagging an entire wall with your choice of spray paint. The drawback, of course, is that it’s a completely random process involving a wildly waving spray paint arm and a bunch of shapeless scribbles. But hey, at least you’ll avoid that miserable sore finger that comes from holding down the paint can button for too long!

The Senseless Drawing Bot was invented by So Kanno and Takahiro Yamaguchi for the singular purpose of scribbling random lines and swirls of paint on your chosen surface. The bot wheels itself back and forth in a straight line, swinging its metal arm and creating one-of-a-kind works of robot art.

We hear you out there asking “What’s the point?” But like so many other creative works out there, there’s no real answer to that. The Senseless Drawing Bot seems to exist solely to be weird, funny and different than most of the other graffiti projects out there.
