Abstract - A robot is any automatically operated machine
of design when two rotating pedestal are attached to the one pedestal it should be sustain the dynamic and static load within the operation so failure cannot obtained. Fig 1 shows that the arrangement of the pedestal for rotating robot. It shoes that tentative model of the pedestal.by using the FEM we safe that structure with the boundary condition given by respective catalogue.
which replaces and reduces human effort, though it may not look much like a human being or working in a human like manner. Most robots are designed for specific functions within a custom environment for performing aerial tasks. Robots require its own custom manufactured pedestal structure i.e base structure, custom built to size and strength in order to ensure immobility while firmly supporting the robot.in this project we analyze the pedestal which supports the two robots. Firstly we decide the model and created on the ANSYS 15.0 workbench. Then meshing the model in ansys with suitable element and apply the boundary conditions like as forces, moments, fix support. Then getting the result of total deformation and equivalent stresses we decide the design is safe the model of first pedestal and then find the force reaction of the second pedestal with that values safe the final model. The procedure and result of the analysis are described in this paper Key Words: robot pedestal, finite element analysis, optimization, equivalent stress, total deformation
1. INTRODUCTION An industrial robot is a manipulator designed to move materials, parts and tools, and perform a variety of programmed tasks in manufacturing and production settings. The industrial robot is a good for many applications. It is most often used for arc welding, material handling, and assembly applications. They are grouped according to number of axes, structure type, size of work envelope, payload capability, and speed. Robots require specialized supporting structure to accurately hold the workpiece during the operations. Most robots are designed for specific functions within a custom environment for performing aerial tasks. Each robot usually requires its own custom manufactured robot pedestal, custom built to size and strength in order to ensure immobility while firmly supporting the robot. Each robot usually requires its own custom manufactured Robot Pedestal, custom built to size and strength in order to ensure immobility while firmly supporting the robot. Most robot suppliers do not offer a Robot Pedestal as per client application. Due to the nature of the custom environment and application, no standard Robot Pedestal design will work every time. In fact, a custom height Robot Pedestal will be required 99% of the time.it is crucial part

Fig.1 Similar Structure to be designed The techniques of analysis and simulation of mechanical systems using the finite element method allows researchers and mechanical engineers to build mathematical models and to analyze the static and dynamic behavior of the structural elements directly on the computer, and optimization calculations, simulations, etc. Approximate numerical solutions, obtained through modeling for the proposed problems, have the advantages such as it can be applied to bodies and real phenomena, regardless of their degree of complexity are converge to solutions of proposed problems (results may be obtained with the desired accuracy) also you can view the pictures, charts, graphs - intuitive and more diverse than in the case of exact solutions. allows to obtain a solution in a reasonable time with the economically advantage.[1]
