3D Printed Bionic Arm

Abstract

EMG sensor electrodes are used to detect signals from the muscle fibers and generate the required output. The basic operation of EMG signal processing are signal amplification and filtering. This low costed bionic arm is 3D printed which has its own advantage. The acquired signal is passed through various stages of filters and amplifiers for amplification and noise reduction. The analog signal is converted into digital signals. These digital signals are used to control the servo motors by using microcontroller. Specific features are extracted from the obtained EMG signals. The EMG electrodes are connected to the servo motors which are fitted inside the 3D designed arm. Mostly PLA plastic is used as a 3D printed filament.
