Guitar-Playing NXT
Here's the description from the creator:
"This robot can play five chords using three NXT motors. The guitar is an ordinary acoustic guitar tuned in "open C" - it plays a C chord when the strings are strummed without the other hand touching the fret board.
And I can say that the robot plays the guitar better than I do!"
Comments
If we could apply some fast fourier transforms (FFT) to the microphone recordings (maybe with a FFT java library for lejos),
then it would not be difficult to automatically tune a guitar.
I mean a NXT robot to use microphone, FFT and 4? motors to determine and correct the pitching of each string.
