This Arduino-powered robot is like a Roomba with a paintbrush
Can robots paint? More specifically, can they create art? The second question is, of course, open for debate, but Technovation’s robotic build shows that they can indeed wield a paintbrush.
The device, shaped vaguely like a Roomba vacuum cleaner, uses a pair of NEMA 17 motors for movement and a third to rotate a sort of brush turret. A servo attached to the pivoting arm positions a brush up and down, dipping it into paint, and bringing it to the drawing surface as needed.
Control is via an Arduino Uno with a CNC shield. The project is capable of producing art randomly, or be programmed to execute pre-defined patterns.
You can see in action in the video below, while instructions to make your own are available in Technovation’s tutorial.
