Five fingered prothesis robot hand

Mechanical hand systems, are among the developing technologies. These developments would be either improving the variables such as flexibility and velocity or recovering the end-effectors through redesigning. There are many kinds of end-effectors used in robotic technologies. In some cases, these effectors may not be sufficient. These circumstances would cause to develop new end-effectors. During changes when new end-effectors with high technologies are intended to develop, animates having ability to move and to work and also having flexibility are taken for example. In this study, robot hand called as KTÜ Hand is designed to have five fingers and structured as serial manipulator. Robot hand is designed to play the melody having programmed code by using arduino control system. Designed robot hand includes one thumb and four fingers. Fingers consist of three degree of flexibility (dof) and thumb consist of one dof. Power transmission mechanism, trigger belt and gear pulley are actuated by micro servo motors. KTÜ Robot Hand is produced by 3d printer through using abs plastic material. In our designed system, KTÜ Robot Hand is actuated in linear axe by using step servo motor. And thus it is able to press the piano key. Step servo motors and micro servo motors are actually controlled by using arduino mega. Key Words: KTÜ Hand, piano, Robot Hand
