The present research consists of the mechanical and electronic design of a hand prosthesis that is composed of a parallel robot platform to perform the movement of the wrist, on this platform 3 universal joints will be mounted that will be connected to the base of 3 linear actuators that represent a prismatic joint for the extension and flexion movement of which will be cont rolled by an Arduino Mega type board. The design of the prosthesis consists of a base that represents the palm of the hand joined to the proximal phalanx, which will be attached to the medial phalanx and finally attached to the distal phalanx assembled by means of mechanical couplings that will represent the fingers of a human hand, the mechanism for its movement will be through the medial internal link and proximal internal link to the interior of each finger interconnecting each phalanx and finally connec ted to th...
