Abstract
This study aims at developing a violin playing robot that is able to produce expressive sounds. This leads us to understanding human Kansei. In this paper, we will describe bowing motion of an anthropomorphic robot arm that we developed and analytical results of produced sounds. The robot arm has 7 D.O.F and is driven by D.C. motors installed in each joint. We confirmed that the robot reproduced a same sound every time. We also observed vibration of 4 Hz in the sounds. We considered that the vibration was caused by natural frequency of the bow.
