The StreetWriter project expands on the research
gained from the successes of the 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 messages that
are several hundred feet in length.
