A team of three PhD students constructed this ‘multi-mallet automatic drumming instrument (Madi)‘. Their Expressive Machines Musical Instruments site is dedicated to building instruments like this and they recently showed their work at the first annual Guthman Musical Instrument Competition. A ‘low-stakes X Prize’ for musical instruments. 25 applicants were chosen to show their unique musical instruments for $10K in prizes. We like the team’s Madi because it’s adapting a traditional instrument and then pushing it to the limit. It reminds us of the Crazy J mechatronic guitar from 2005. You can see a video of the Madi playing below.
