PENGOLAHAN SIGNAL ELEKTROMIOGRAFI PADA LENGAN UNTUK MENGGERAKKAN LENGAN ROBOT DENGAN 3 DOF

Muscle is a part of human body that has function in human movement system. The function of electromyography in the muscle is to detect the electric potential produced by the muscle in contraction and relaxation that can be used to control a system. This final project utilizes the electromyography signal to make move a robot arm. Electromyography signal processing is transpired in hardware side that is using comparator series, one shoot multi vibrator series, and logic series. Electromyography recorded by instrumentation series will be strengthened. The amplitude of the electromyography signal will be compared with the smallest value of the electromyography signal itself on this comparator series. The deviation of t value on the comparator series has to be found for to be altered to the input value before entering the one shoot multi vibrator series. The signal output will be a square signal with the same signal length compared to the electromyography signal by the identified t value. The logic series is used to know which muscle that works; that the three of the one shoot multi vibrator series output will be compared to know which output that moves first in each movements.
