"In this paper, the authors' aim is to build up a ""Humanoid robotic arm"" from the garbage materials which can support people in their daily life and also in industry. The vital component of such a robot for handling objects is the construction of its arm gripper. The design of their robotic arm is based on the observation of the motion range of a human arm. They have tried to depict simple mechanical knowledge to build this arm. Five DC motors are used here in five gear boxes."
