GuitarBot Brings Together Art and Engineering

Not only does the GuitarBot project show off some great design, but the care given to the documentation and directions is wonderful to see. The GuitarBot is an initiative by three University of Delaware professors, [Dustyn Roberts], [Troy Richards], and [Ashley Pigford] to introduce their students to ‘Artgineering’, a beautiful portmanteau of ‘art’ and ‘engineering’.

The GuitarBot It is designed and documented in a way that the three major elements are compartmentalized: the strummer, the brains, and the chord mechanism are all independent modules wrapped up in a single device. Anyone is, of course, free to build the whole thing, but a lot of work has been done to ease the collaboration of smaller, team-based groups that can work on and bring together individual elements.

Some aspects of the GuitarBot are still works in progress, such as the solenoid-activated chord assembly. But everything else is ready to go with Bills of Materials and build directions. An early video of a strumming test proof of concept used on a ukelele is embedded below.

Cythbot, pneumatic Guitar Hero

cythbot

Here’s yet another robot hoping to dominate the human race through the power of ROCK. Cythbot was built to demonstrate Cyth Systems machine vision systems. The device uses a camera to watch the Guitar Hero monitor and identify notes for button presses. The strum bar is then triggered after a delay. The notes are identified solely by pixel intensity since star power can cause them to change shape and color. All button presses are done using pneumatics. The whole system is self-contained and doesn’t require a separate computer for processing. Our favorite part is that the controller remains completely unmodified and the industrial light tree used to indicate notes. The team says that the pneumatics aren’t quite fast enough to hit 100%, unlike some humans. Video of the bot in action after the break. Continue reading “Cythbot, pneumatic Guitar Hero”
