A robot can be defined as a programmable, self-controlled device consisting of electronic, electrical, and mechanical unit. The elements which are common to all robots can be considered as the basic elements and are as follows:- ? Manipulator:- ? Controller: - ? End Effecter: - ? Sensors: - ? Energy Source: - The robot manipulator can be divided into two sections, each with a different function: Arm and Body and the Wrist - The current design of the robotic arm consists of manipulators that have been over designed to meet reliability requirements. Hence these manipulators have been designed in a way that they do not make best use of material. They have a low payload to weight ratio. This limits the payload capacity and increases the power requirement for movement of the arms. Attempt has been made to optimize the design of the arms using FEA as a tool. Strength and stiffness have been kept as design criteria while optimizing the weight of the moving arms. The results have shown corresponding reduction in power requirement for arms movement..
