Abstract: Robotic arm application is gaining more importance in the present era. The accuracy and precision of a robotic arm is important in various applications. The available robotic arms have lesser accuracy. This paper presents an artificial arm which is capable of performing the task like a human arm like picking up, moving an object and gripping a substance. In the human arm, the bending or movement depends on sensor data and muscular movements, which are replicated using flex sensors, motor and string arrangement. Servo motors were used to actuate the movements of the robotic arm. The designed system can be developed with comparatively much lesser cost involvement and thus is more acceptable to the common mass. The low power requirement is also one of the novel attributes of the proposed system. The accuracy of this system is more than satisfactory and can be a potential tool for human assistive applications.
