A new robot will enable street artists to create murals in places that were previously impossible or too expensive to reach. Estonia-based company SprayPrinter has developed a prototype for a robot that can scale buildings and towers to create a street art painting of whatever image it's programmed to. In its first full-scale demonstration, it created a giant, five-color mural of a woman on a chimney with just one pass by switching colors as it sprayed. SprayPrinter has developed a prototype for a robot that can scale buildings to create street art. 'The Chimney hack was very different from what we have done so far,' Mihkel Joala, inventor of the original SprayPrinter, said.
