“…These robots are worthy examples demonstrating the excellence of robot hardware design and control technology, but they function by stringently executing pre-programmed control commands. The present authors have also developed a violin-playing robot by modeling a violin bow as a spring-damper model, and attempted to improve the robot's sound quality by using the Q-score to evaluate the sounds being played [6], [7].…”

“…The proposed robot hand will generate a more accurate sound by controlling the pressing force applied to a violin string during violin playing by the violin-playing robot. The effectiveness of the proposed robot hand was demonstrated by comparing the quality of sound generated by it with that generated through the violin fingering of a human violinist on the basis of an existing sound quality rating system [7].…”

“…In particular, a self-treating method for people who stutter, which entails listening to one's own voice and understanding its state, has been proposed [5]. Researchers have determined that this auditory feedback technology is the key element of HRI, and the present authors have accordingly developed a sound quality rating system for improving an existing violin-playing robot by combining this system with auditory feedback [6], [7]. The present work introduces a robot hand and a robot finger that perform the role of violin fingering for a violin-playing robot.…”

This paper proposes a robot hand for a violin‐playing robot and introduces a newly developed robot finger. The proposed robot hand acts as the left hand of the violin‐playing robot system. The violin fingering plays an important role in determining the tone or sound when the violin is being played. Among the diverse types of violin fingering playing, it is not possible to produce vibrato with simple position control. Therefore, we newly designed a three‐axis load cell for force control, which is mounted at the end of the robot finger. Noise is calculated through an analysis of the resistance difference across the strain gauge attached to the proposed three‐axis load cell. In order to ensure the stability of the three‐axis load cell by analyzing the stress distribution, the strain generated in the load cell is also verified through a finite element analysis. A sound rating quality system previously developed by the authors is used to compare and analyze the sound quality of the fourth‐octave C‐note played by a human violinist and the proposed robot finger.
