Printer Drivers

Two projects from the Institute for Applied Autonomy:

“GraffitiWriter is a tele-operated field programable robot which employs a custom built array of spray cans to write linear text messages on the ground at a rate of 15 kilometers per hour. The printing process is similar to that of a dot matrix printer. GraffitiWriter can be deployed in any highly controlled space or public event from a remote location.” See also instructions on how to build your own.

“The StreetWriter project expands on the research gained from the successful Robotic GraffitiWriter project. The system consists of a custom built, computer controlled industrial spray painting unit that is built into an extended body cargo van. The vehicle prints text messages onto the pavement in a manner much like a dot-matrix printer. The expanded width of StreetWriter allows for messages and simple graphics that are legible from tall buildings and low flying aircraft and is capable of rendering message that are several hundreds of feet in length.” Lots of pix and videos at both sites.

See also Bike Writing, a project to turn any bicycle into a printing, street writing device that prints as you ride.

“The bike writer incorporates interchangeable rubber stamps into the wheels so that while riding, the user can inscribe text into public space. An ink roller is applied to the wheel through a simple mechanism, which is activated by squeezing the rear break handle. This activity is extremely covert and effective.”
