A builder named Bruce spent six years developing MegCell Pulse, a pair of 3D-printed robots that attach to an acoustic guitar and play it from digital tablature input. One robot handles fretting, the other handles plucking via six individual plectrums. The result is analog acoustic sound produced entirely by machine, with no human hands required.
The system runs on gears, magnetic actuators, and articulated arms housed in a printed frame. Its constraints are real: it cannot traverse the full fretboard and cannot execute slides between frets. Those limitations matter for anyone considering what repertoire is actually playable, and the original article is worth reading to understand exactly where the mechanical ceiling sits.
MegCell Pulse is live on Kickstarter. You cannot buy it assembled. The top support tier is $100 and delivers 3D print files, an assembly guide, control software, and a full parts list. That build-it-yourself requirement is the detail most coverage buries. Read the original for the demo videos, which show exactly what the system can and cannot pull off in practice.
