We have been studying the application of the musical saw, an unknown and advanced tool, to a cooperative humanoid robot for industrial use. A sound feedback system using mallet strike technique and the sound generated by the technique was constructed in the previous reports. The system enables tuning to a target frequency and control to enhance the purity of the pronunciation. However, the bow manipulation often used by skilled players has not yet been examined. In addition to striking, we concentrated on bowing motion, which is used in musical saw manipulation evaluation. Furthermore, it is necessary to generate self-excited vibration by stick-slip based on manipulation. Therefore, it is necessary to control the pressure and speed between the bow and the musical saw to confirm the occurrence of self-excited vibration and the vibration itself. In this study, in addition to the generation of sound by the self-excited vibration, the pure sound nature of the vibration will be discussed. This is different from the approach to suppressing self-excited vibration that has been implemented in previous studies. Furthermore, we will show how an industrial cooperative humanoid robot can be used to manipulate a musical saw with a bow skillfully.
