Climbing graffiti robot can create giant murals
    2017-August-30  08:53    Shenzhen Daily

A new robot will enable street artists to create murals in places that were previously impossible to reach.

Estonia-based company SprayPrinter has developed a prototype* that can scale buildings and towers to create a street art painting.

In its first full-scale demonstration, it created a five-color mural of a woman on a chimney with just one pass by switching colors as it sprayed.

SprayPrinter launched in 2016 with an app-controlled device designed to attach to a spray paint can that enables users to create murals by simply moving the can across the surface — the device tracks the movement and communicates to the device via Bluetooth, telling it when to spray. The new, larger device now can hold five cans.

The computer knows how to create the image by reading a text file consisting of coordinates and laser power values. The computer then sends lines of code (called G-code) one by one to the main controller to execute the commands.

Then another controller measures the laser control pin for different pulse widths that ranged from about 0-1,000 microseconds.

These values are then wirelessly sent to the printhead that holds the spray paint cans to trigger different colors, with all of this happening about 100 times per second.(SD-Agencies)
