Abstract
The goal of this study is to develop an anthropomorphic violin-playing robot to investigate the method to express "sensibility" richly. In this paper, we report a new robot body and a new violin-holding mechanism. Because the width of the robot body previously we developed is larger than the typical human size, it is difficult for the robot to use a bow near the frog. Therefore, we redesigned the robot body. As a result, the robot can use a bow near the frog. Also, we built a new violin-holding mechanism. Because it is difficult to place the violin at the identical position every time, it takes large time to identify the position of the violin. Also, after the performance, its position may change. In addition, dimensions of each violin are slightly different from each other. The developed mechanism fixes the violin at four points. We measured the position errors when we remove the violin and set it again to the mechanism and found that the position error is 1.67 mm in average.
