    Generación de movimiento de un mecanismo watt i para obtener las posiciones prescritas de agarre similar a las falanges de la mano de una persona
    (Universidad Nacional de Trujillo, 2016) Pesantes Leon, Daniel Renato Alonso
    This research named “On motion generation of a Watt I six bar mechanism to achieve grasping prescribed positions similar to phalanges of a human hand”, it has developed using analytic synthesis through standard dyad method to design four bar mechanisms, applied to six bar mechanisms. To determine the mechanism, it has defined three prescribed positions corresponding to three cylindrical grasping positions of hand phalanges, all of these belong to a straight line of a link coupler (distal phalanx). Two of these three positions were the start and the final movement position of a finger prosthesis, the third position had taken an intermedium position. The analytic synthesis through standard dyad method applied to motion generation specified for three positions of a watt I mechanism points coupler allowed find link dimensions corresponding to proximal (49.984mm), medial (30.008mm), and distal (25.770mm) phalanges of a finger prosthesis in grasping movement, also, the positions of non-specified fixed pivots corresponding to this Watt configuration were obtained. By means of this method, the synthesis of each link was done, having in mind the ergonomic of a person with finger prosthesis, adjusting shapes and measurements of each link within ranges of standard sizes, and then, design finger prosthesis with Solidworks engineering software
