Design and Analysis of Articulated Inspection Arm of Robot K.Gunasekaran T.J Institute of Technology, Engineering Design (Mechanical Engineering), kgunasekaran.25290@gmail.com Abstract— Nowadays Robot play a vital role in all the activities in human life including industrial needs. There is a definite trend in the manufacture of robotic arms toward more dexterous devices, more degrees of-Freedom, and capabilities beyond the human arm. The ultimate objective is to save human lives in addition to increasing productivity and quality of high technology work environments. The objective of this project is to design, analysis of a Generic articulated robot Arm. This project deals with the modeling of a special class of single-link articulated inspection arms of robot. These arms consist of flexible massless structures having some masses concentrated at certain points of hollow sections at the beam. Some aspects of the articulated Robot that are anticipated as useful are its small cross section and its projected ability to change elevation and maneuver over obstacle require large joint torque to weight ratios for joint actuation. A knuckle joint actions actuation scheme is described and its implementation is detailed in this project. The parts of the (AIA) arm are analyzed for deflection and stress concentration under loading conditions in different angles.

1 INTRODUCTION

A

At present, the main interest is to protect nuclear workers in highly contaminated areas with hostile environmental conditions by the use of robot in nuclear power plants to reduce human exposure not only to radiation, but also to hot, humid and oxygen-deficient atmosphere due to which the research specialist in the field of robotics proposes a great variety of robot configuration and functional capabilities to be used in nuclear power plants. The wheeling robot, tracked vehicles are the most commonly used configuration for mobile robot.

completed with a stereophonic bi-directional set of audio which provides signals for sound inspection. To carry out close inspection tasks of the vacuum vessel first wall using a long reach robot is called the ―Articulated Inspection Arm‖ of robot (AIA).

Fig1. 1 Robotic Design The present robotic system is made up of mainly three sub-systems: sensory head; teleportation and control panel and the inspection mobile robot with vision, sound and also temperature cover 90% of all inspection tasks required in BWR nuclear power plants by the method of pan-tilt mechanism. So that it’s easily plugged in various mechanical inspection robot. A video camera is used for the purpose of inspection through stereo vision equipment which are produced by stereo Graphics, has been integrated in the tele-operation panel. This stereotype system is greatly used in guiding the mechanical robot through cloistered areas. The tele-presence is

Fig1. 2 Industrial Robot There is a possible presence of high stresses and high deformations in bending and torsion in these structures. The load depends on the articulated structure. The prepared model has got to be realistic with a good knowledge of the end-effectors position. The model of the complete robot is the assembly of the five elementary models are already described before. It provides the deformation and position of the structure for any given joint position and loads. The calculation is iterative due to the nonlinearity which are induced by the largely displaced cumulative effect of the deformations.
