The development of this project has the goal of controlling an robotic arm .Android provides the support of Blue-tooth. The control for the android implemented with the development board mentioned above is capable of sending digital Commands to each one of the part to control their position as well as receive and process commands .It has the 4Dc motor-driven robot arm. Since the arm has a few joints, we can imagine, our human arm, in addition to shoulder, elbow, and wrist, coupled with the finger joints; there are a lot of joints. So this robot is the same, with six dc motors to achieve a simple structure. So this motors are been controlled by Android mobile by communicating via Bluetooth.
