Drummer Jason Barnes, who only has one arm, has been collaborating with engineer Gil Weinberg of Georgia Tech's Institute for Robotics and Intelligent Machines to develop a cyborg arm that enables Barnes not only to play his kit again, but to "play at speeds not humanly possible… and play strange polyrhythms that no human can play." Weinberg and Barnes have now launched a Kickstarter to build another prosthetic cyborg arm that Barnes can take on the road. From IEEE Spectrum:
The Cyborg Drummer Project Kickstarter is looking to raise $90,000; of that, $70,000 will go straight to production of the new arm. A big chunk of the cost comes from trying to replace the "couple of computers and a technical team" that are currently required to operate the arm with components that are portable, self-contained, and user operated. The remaining $20,000 will go towards organizing concerts and making recordings so that folks who contribute will be able to hear and enjoy some of the result, potentially in person.
One of the unique things about the prosthetic that Weinberg and Barnes want to build is that it will be partially autonomous. There are two drumsticks: Barnes controls one; the other operates autonomously through its own actuator. The arm listens to the music being played (by Jason and the musicians around him) and improvises its own accompanying beat pattern. It's able to do this on the fly, and if it chooses to, is capable of moving at speeds far faster than a human drummer can.
