This is awesome, from Gibson Robot Guitar official site:
On December 7, 2007, Gibson will change the guitar world forever. Again.
True to the spirit of innovation that inspired Gibson to invent the legendary Tune-o-matic bridge, the powerful humbucker, and the revolutionary Digital Les Paul, Gibson proudly presents the Gibson Robot Guitar—the world’s first guitar with robotic technology.
Since the dawn of the instrument, musicians have come to accept the guitar’s imperfections and lack of tonal precision as necessary evils. Onstage and off, guitarists have fought to stay in tune. Every music lover and performer has had to suffer through the show—halting, mood-killing atonal droning of a loudly amped guitar being brought into tune. And in the studio, or at home, imprecise intonation throws the guitar in and out of tune, up and down the neck, as the instrument requires tweaking with each season and at times with each string change.
For as long as the guitar has existed, guitar lovers have had two choices—live with a temperamental and out-of-tune instrument or make frequent trips to the shop for setups. Not anymore.
Introducing the Gibson Robot Guitar. All you have to do is play it.
