N2 - Available prosthetics hand is expensive and beyond the ability to buy for the amputee, especially in the developing country. The designing a low-cost prosthetics hand is very important because it can be fabricated with a minimum cost. Therefore, this study aims to design an anthropomorphic prosthetics hand with a low cost and open source to the public. In this study, the prosthetics hand composed of an anthropomorphic artificial hand, motor servo and electronics circuits. The anthropomorphic artificial hand was designed using Blender (the three-dimension (30) application program) and Cura Ultimaker (the 30 printing application program). The material used to build the hand was polylactic acid (PLA). The electronics circuit consisted of dry electrodes, EMG amplifier, microcontroller Arduino, and two servo motor. In the implementation, the cost to build the prosthetics hand was US$ 161, and the weight is 678 grams. The EMG signal had a different pattern and amplitude when the hand performed the close and open motion. The EMG signal ranged-8 mV to 8 mV, and-2 mV to 2 mV for close (grasp) and open (relax) motion, respectively. Based on a predefined threshold voltage (1 mV), an Arduino microcontroller decided whether the servo motor was activated or not. Overall, the main contribution of this study is that the prosthetics hand can operate using a single channel of EMG signal. The prosthetics hand able to grasp the five standard objects used by people in the daily activities. This design can be produced with a low cost and local spare part.
