1.2.9 Motion Detection

Оглавление

Patients who suffer from any kind of impairment are not able to produce proper movement. The robotic systems may help in determining their intention of motion and aid it by helping them to move. Production of torque in the desired direction and compensation of kinetic and breakaway friction was presented [70]. Investigation of support vector machine (SVM) identified the sEMG signals from the muscles and produced motion in that direction [71]. A method enhancing the degree of freedom of the patient and supporting the motion was developed. It was tested on ARM in III robotic system [72]. Based on the EMG signals produced by muscles, the torque and intention of motion were determined [73]. The visualization for the intention estimation algorithm is denoted by Figure 1.2 for inquisitive readers.

The intended motion of hand for hemiparetic hand patients was done using sEMG signals. It was introduced in the form of a soft glove [74].
