Dot-dabbing drones paint pixellated pictures

by • August 3, 2016 • No Comments

We hear of drones being utilized to do a lot of things, but the creation of art is one that does not come up too frequently. That may be of to alter, yet, as a desktop scientist of Montreal’s McGill University has been via small quadcopters to paint portraits on the campus’ hallway walls. Down the road, he hopes that larger drones may be utilized to turn it into murals high up on the sides of buildings, or in other hard-to-reach locations.

For the past two years, Prof. Paul Kry has been via mini-drones armed with ink-dipped sponge tips to turn it into portraits of folks such as Alan Turing, Grace Kelly, and Che Guevara.

The aircraft use a technique known as stippling, in that fish images are created up of an array of individual dots. A desktop remote-control process uses a motion-capture camera and custom algorithms to plan the drones’ flight paths, and to manufacture corrections as errors occur – these can be cautilized by facts such as breezes in the hallways, that send the copters slightly off-course.

The portraits done so far range in complexity of 400 to over 2,000 dots. Of course, the drones have to periodically stop to get fresh batteries, and to have their sponge tips re-inked. To that end, Kry has been looking into tethering the quadcopters to an AC power donate, so no battery alters are necessary. He’s in addition attempting a wall-mounted ink pot, that the copters can dab their sponges in at regular intervals.

Ultimately, yet, he’d like to see the innovation go bigger.

“There’s this rad mural festival in Montreal, and we have giant surfaces in the city that end up getting awe-inspiring artwork on them,” he says. “If we had a particularly calm day, it may be rad to try to do a thing on a larger scale like that.”
