ストローク奏法を用いたギター演奏ロボットの開発と演奏の評価

抄録

As an example of human-machine interaction, research on musical instrument ensembles between humans and machines has been conducted. In this study, we propose a robot system that can play an acoustic guitar. There have been several previous studies of guitar robots, but they have been limited by (1) the heat generation problem of the string pressing mechanism, (2) the difficulty of independently pressing the strings, and (3) the difficulty of controlling the strings. (2) The strings are independently plucked, and the stroking technique is not the same as that used by humans. (3) It is not practical because of these problems. In this study, we solved these problems and developed a guitar robot system that can play in concert with humans. In an evaluation experiment using subjects who could distinguish between the performances of humans and robots, the correct answer rate was about 70%, and we confirmed that even humans could not distinguish between the two performances. The effectiveness of the proposed system was demonstrated.
