Execution and description of dexterous hand task by using multi-finger dual robot hand system - realization of Japanese sign language

A multi-fingered dual robot hand and its control and programming system, e.g. the state action event network (SAEN), have been developed to achieve dexterous hand works in human mimetic approach. Some dexterous hands tasks such as paper cutting and chopsticks handling have also been achieved by using this system. The final goal of the study is to perform the sign language as a means of communication with the hard of hearing people. We deal with sign language tasks by using our SAEN system. As the result, it is shown that our software system is quit effective for implementation, but the hardware does not have enough facility for the sign language.
