| Outline of Final Research Achievements |
In this study, we consider the development of myoelectric human-robot interfaces that enable intuitive control of complex robots based on the user intention estimated from myoelectric signals. More concretely, we propose a motion intention recognition method based on the surface Electromyography (SEMG), robust to the factors of 1) postural change, 2) sweating and 3) muscle fatigue, all of which can largely change the relationship between the sEMG signal and the motion intention. Our method is achieved with using pattern matching techniques, and without either other sensors for measuring the postural change, the sweating and muscle fatigue, or physiological models of human body. Through the subjective experiment under the postural change, the proposed method resulted in better performance than that of previous methods.
