Abstract In this manuscript, by utilizing CAD (CATIA), 3 diverse arms of robot have been made. Here, there might be robot arm in divergent shapes like hexagonal, rectangular arm robot models & they are broke down with constant limit conditions with 3 distinct materials (AISI-1050 steel, carbon fiber, kevlar29). Static examination, modular examination& exhaustion examination has been performed. From these investigations, distortions, recurrence esteems, stress life of part & wellbeing factors were watched for all models. From every one of these outcomes here we will close which material has less distortion & which material has fewer measures of pressure esteems. From every one of these outcomes we might attain a thought that robot use for various conditions such as minimum weight / minimum pressure creating robots. Examination of the created structure with the first plan of metallic one is finished. It is seen that there is a noteworthy increment of firmness of the robot arm while diminishing its mass & latency to accomplish an extremely high explicit solidness, explicit quality & incredible powerful execution which will bring about great efficiency according to our necessity which is the ideal point of this task
