Prosthetic Arm Control Using Electromyography (EMG) Signal

Due to accidental trauma, war, and congenital anomalies, human beings are suffering since a long ago. Also, amputation and deformity have been carried out. Human hand has complex hierarchical control with large number of degrees of freedom. Thus, the efforts need to perform different movements are relatively small. Beside this, prosthetic arms are only an imitation of the natural hand, with considerably decreased movement freedom & clutching competencies. This paper presents the artificial myoelectric arms that an amputee needed to replace his/her amputated arms with prostheses. In this paper, acquisition of the most useful bio-signals for the prosthetic arm control is demonstrated. In addition, the process of extracting control information from the raw myoelectric signals is described. This paper describes a method to control artificial arm by dint of EMG signals.
