Ever seen a bit of graffiti in a strange location and wondered how the graffiti artist got up there? It might have been a drone rather than an athletic teen. Disney research has just published an interesting research paper that describes the PaintCopter: an autonomous drone fitted with a can of spray paint on a pan-tilt arm. It’s more than just sticking a paint can on a stick, though: they built a system that can scan a 3D surface then calculate how to paint a design on it, and then do it autonomously. The idea is that they want to use this to paint difficult-to-reach bits of theme parks, or to add seasonal decorations without sending someone up a ladder.
The PaintCopter is built from a DJI M100, with an Nvidia TX2 and Intel UP processor boards added to give it some more processing power
