Motion analysis of arm by use of myoelectric signal

In order to operate a robot, various devices are proposed such as a joystick, a master-slave arm, and keyboard. However, these devices have problems such as response speed. Instead of these devices, biosignal such as myoelectric signal is used as an interface between human and machine. The myoelectric signal represents the forces generated by muscle. In this paper, we propose to use the myoelectric signal for motion analysis of arm. We analyze four kinds of motion by using myoelectric signals measured from four kinds of muscles by using map and threshold.
