Yes, the ukulele is being played by a robot! It sounds like a first-year student, though. The use of RC servos limits the speed of the plucking, and it sounds like the software hasn’t been written to allow for nuanced timing of the plucks, to give the music ‘character’.
It might be possible to program this setup to make more soulful music, but the servos don’t offer much control over the plucking rate. Perhaps a few days poking at the firmware would liven it up a bit.
