Abstract
This paper describes an EMG (electromyogram) control system using general-purpose microcomputer for ultrasonic motor, as a basis on development of elbow disarticulation prostheses combined by ultrasonic motor and magneto-rheological (MR) fluid. Ultrasonic motors have some special unique features, such as high-torque under low-speed operation, compact size, and no electromagnetic noise. In this study, we developed an EMG control system for ultrasonic motor using general-purpose microcomputer (NEC 78K microcomputer), and it was proved effective in fundamental experiments.
