We’ve already seen cities turn to technology to combat graffiti, but it looks like the tables could one day be turned, at least if designer Stefan Rechsteiner has his way. As you can see above, his so-called “Couleur sur l’Objet” robot concept would be able to climb walls (relying on suction, it seems), leaving a trail of graffiti behind it. That would apparently be entirely done using software to plot out its course ahead of time, although we’re sure it could also be rigged with a remote control to allow for a little freestyle spraying. Of course, the chances of anyone actually releasing such a bot are pretty slim (at least for graffiti-ing purposes), although there’s nothing stopping you from taking a certain DIY-friendly solution and trying to build your own.
