To achieve high controllability of the prosthetic hand, kinesthetic sensory and its feedback mechanisms are indispensable. We have investigated bio-inspired kinesthetic sensory mechanism l. In the previous report, we proposed a unique sensing mechanism based on the analysis of the motor power consumption time series using reservoir computing (RC), however, there was a problem in the sensing accuracy. In this study, based on the understanding that the fluctuation imposed on the RC input signal affected the computation, we investigate the improvement of the sensing accuracy by modifying the supervised signal to avoid the fluctuation.
