Abstract
In the case of some elderly persons, the environment perception ability is sometimes deteriorated. To assist the daily living motion of those people, power-assist robots with the perception-assist have been proposed. The power-assist robot with the perception-assist assists not only the user's motion but also the user's interaction with an environment, by applying the modification force to the user's motion if it is necessary. The effectiveness of the performed perception-assist is judged by the EMG signals. In this paper, we measure the EMG signals and EEG signals at the same time to observe the features of these signals when users use the power-assist robot. Specifically, in order to use EEG signals as the criteria of the effectiveness of the perception-assist in addition to EMG signals, these signals are observed when the robot performs the perception-assist.
