In this project the creation of an articulated hand is carried out indicating the first components in which the prototype of the robotic hand is formed. The design of this project was carried out in SOLIDWORKS, a program in which it was possible to dimension and design the model of operation of this The electronic development will be conditioned to the needs and parameters hand and it will use an ATMETGA microcontroller on the custom-built card and for that functionality also required the card which will capture the electromyographic signals for the robotic hand to function properly.
