Spray-Painting Robot
Check out this massive 98-foot-tall mural painted on a chimney stack in Estonia. Can you believe it was made by a robot?
The entire process took 14 hours and 40 cans of spray paint. The robot in question was invented by Mikhel Joala, co-founder of SprayPrinter. SprayPrinter is a tech company focused on redesigning traditional methods of spray-painting.
In an interview with Hyperallergic, Aet Rebane (Head of Media Relations for SprayPrinter), said that “Basically, the image file that the computer read was a text file consisting of coordinates and laser power values. The computer sends lines of code one by one to the main controller that executes the commands.” She continues, “Another controller measured the laser control pin for different pulse widths that ranged from about zero to 1,000 microseconds. Then these values are wirelessly sent to the printhead to trigger different colors. Everything is happening about 100 times per second.”
