Robotic artist can spray paint murals

New York: Scientists have invented a “smart” paint spray can that robotically reproduces photographs as giant murals. The computerised technique which basically spray paints a photo is not likely to spawn a wave of giant graffiti but it can be used in digital fabrication, digital and visual arts, artistic stylisation and other applications, said the team from Dartmouth college and colleagues.

The system uses an ordinary paint spray can, tracks the can's position relative to the wall or canvas and recognises what image it "wants" to paint. As the person waves the pre-programmed spray can around the canvas, the system automatically operates the spray on and off button to reproduce the specific image as a spray painting.
