◆この研究室は以前にもShimonという歌い、作曲し、マリンバを演奏するロボットミュージシャンを開発し、他の音楽をサポートするロボットも制作しています。ギターは音楽的な表現力が豊かな楽器であり、ロボットにとっては難しい楽器の一つですが、その難しさに挑戦し、ロボットミュージシャンの音楽性を高めようとしています。

Abstract
We introduce a newly developed robotic musician designed to play an acoustic guitar in a rich and expressive manner. Unlike previous robotic guitarists, our Expressive Robotic Guitarist (ERG) is designed to play a commercial acoustic guitar while controlling a wide dynamic range, millisecond-level note generation, and a variety of playing techniques such as strumming, picking, overtones, and hammer-ons. To allow for these functionalities, we recorded and modeled human guitarists and implemented our findings in hardware and software design. The ERG’s final construction includes a robotic cobot arm for strumming and plucking, as well as a 12-motor fret-shifting module that can move across the guitar bridge. We evaluated the ERG dynamic range, speed, microtiming control, and guitar techniques using both objective and subjectivemethods. The objective benchmarks and subjective ratings demonstrate that the ERG can perform with human-level expressivity.
