Outline of Final Research Achievements

In this study we built a system for a performance feedback system of a violin-playing robot. First, we fabricated a robotic right hand that can adjust the bow force, taking advantage of an idea from the soft robotics. Then, we built a system that can adjust the bow force after the performance, by evaluating the bow force. As a result of the experiment, we confirmed that the system can reduce the fluctuation of the sound pressure value. In addition, we also built a system using reinforcement learning, which can determine the bow movement for a simple musical piece with tow bars.
