In order to contribute the science-technology for the traditional culture.

Abstract

The Karate and Ryukyu entertainments are the traditional culture that attention to Okinawan prides in the world. The sanshin (three stringed musical instruments) was introduced to Ryukyu from China more than 600 years before (1392 around) and have played the important role of the Ryukyu entertainments. How we can contribute such traditional entertainments? If we could contribute for such traditional entertainments with science-technology, they will be stimulated both of culture and the science-technology. Recently, the amusement robots, witch give us peace of mind, are in interest instead of the production machine. In this paper, I will describe mainly related to the sanshin, such as, musical score, tone of some musical instruments, history, and the mechanisms of the sanshin performance robot "agasaa", which we developd, in the second half of the lecture.
