Analysis of the EMG Output Characteristic in Response to Activation of Muscle for the Human Intention Judgment

Abstract

This paper analyzes the data of the biological signals for controlling the robot controller through the EMG signal and proves intelligent user's judgment of intention is possible. For that, the DSP control board for electromyogram measurement was designed, it was utilized in the experiments by mounting a circuit for biological signal processing. In order to find the relation between the EMG output form as user muscle contration and human intention, we make a plan the experiment circumstance which is perform specific operation, and extrac tthe output data of EMG repeatedly. The output of the extracted data is converted to digital filtered control signal, and then we proceed experiment that this output form of the data can show the intention of the user. Incertain circumstances, we utilize three kinds of data, biceps and triceps, forearm triceps, and we gain the result data between the concentric and eccentric contraction of muscle during the time of no load.Using this experiment result, we prove that the outputform of the biological signal is associated withthe user's intention,it can be expected to affect the number of studiesof the biological signal processing and control applicationsin future studies.
