In the first case, we assume that some EMG signals that are
necessary to estimate the elbow joint motion cannot be
measured. The robot can estimate the torques of 6 joints except
elbow joint based on EMG signals, and EEG signals are used
to estimate elbow joint motion. The estimation result is shown
in Fig. 8. In Fig. 8, the black solid line is the result which is
estimated based on EMG signals (Only EMG case), the red
broken line is the result which is estimated based on EMG and
EEG signals (EMG and EMG case).
