Giant Robotic Spray Printer

Towering over the eastern Estonian city of Tartu is a lean chimney stack that features a 98-foot-tall mural of a girl holding a potted plant in her cupped hands. The image required 14 hours of labor and 40 cans of spray paint but zero manpower: it was rendered by a little robot that scuttled across the chimney’s surface with five cans of paint on its back — a device its inventors hope will revolutionize the mural industry.
The robot was invented by Mikhel Joala, co-founder of SprayPrinter, a tech company focused on redesigning traditional methods of spray-painting. Previously, it released its namesake devise, a handheld printer that connects to your phone via bluetooth to let you spray-paint a digital image onto a wall, pixel by pixel.
