Abstract: This work is focused on the design parameters and activity of artificial human finger for seven types of grip; cylindrical, lifting box, push button, hook, spherical , tip and key. At first, obtained the ideal kinematics of human fingers motion by analyzing the grips video which were recorded using a single digital camera recorder fitted on a tripod in saggital plane while the hand is moving. A special motion analysis software (Dartfish) the finger joint angles was studied using the video recording. By using MATLAB A program was built to draw the motion of the finger at constant periods, this program could be used to control the motion of human finger in different grips. Then the seven grips above were modeled using static torque analysis, which calculates the amount of torque applied on the fingers joint at each grip depending on the results of the kinematic analysis. The last step of the work was to design the actuator (Muscle Wire) of artificial finger for the seven grips in a simple design approach for artificial finger actuated by (Muscle Wire).
