This thesis makes the design of a wearable exoskeleton for a human hand of adult man, the which fulfills the task of facilitating the movement of flexion and extension of the index and middle fingers to complete clamping actions, this wearable device requires kinematic and dynamic approaches hand in hand to understand the biomechanical structure of the hand and its degrees of freedom. The cinematic model directed the project as a sub-acted mechanism, which all its movements depend on a single actuator, the Flexion and extension are transmitted by moving a tendon for each action, it is in this kinematic model where the desirable trajectories for the flexion of the fingers and it You can find a list of angles that involve the middle and distal joints with the joint proximal which is the direct one involved in the operation of the tendons. In the same way, the model was obtained dynamic of the hand to perform the simulations of trajectories and movements of the hand. The thesis also contains these models where the anthropometric dimensions are considered of the fingers and the correct movements for the action of gripping an object of different size, here raises how is the appropriate closing movement around an object. The detailed design of each sub-system of the project is continued and covers the systems of control as the mechanical and electrical elements that compose it, within the mechanical part is the adaptation analysis of the tendons in the hands one for the task of flexion and another for extension, the material selected for these tendons is Nitinol, which is an alloy of nickel and titanium which can be of a small caliber and at the same time be resistant to withstand the tension exerted by the motor and the exoskeleton, The nitinol was adapted to a glove to act only the index and middle fingers in such a way that when exercising the flexion or extension and both fingers take the same path. In order to act on the tendons, a mechanism is necessary to roll them up and route them, it is designed in a complementary to flexion and extension, that is to say that analogously it exerts tension in a tendon and it releases the other. The main actuator of this system is a motor that is chosen with the torque data found in the dynamic model of the engine supported on the configuration of the kinematic model of the human hand. The user orders arrive through a serial communication with a bluetooth from Matlab to assign the motor position reference.
