At no point in the history of humanity did anyone ever ask for a bagpipe-playing robot that would never get tired. But this is exactly what Instructables' XenonJohn has built with his Ardu McDuino bot that uses a pair of 3D-printed prosthetic hands to autonomously play a bagpipe's chanter. Thanks?
Powered by an Arduino Mega 2560, the Ardu McDuino is an impressive creation to see in action as its individually-articulated fingers are actually covering and uncovering the holes on a real bagpipe, producing the individual notes you hear. For the 12 of you who love the sound of bagpipes, you can get a full breakdown of how XenonJohn built this bot over on his Instructables page.
The current version of the robot's only limitation is that it's still dependent on a human to blow into it, but its creator is working on building an automated air pump so that the Ardu McDuino can play the bagpipes 24 hours a day, seven days a week, without ever getting tired. Hooray?
