The advantage to using robots is to increase productivity and decrease waste. Robots have a extremely high rate of repeatability. They don't have the individual characteristics of a human operator. Robotics takes human error out of the equation, not to mention that they never call in sick or ask for raises. Remember, robots are basically like computers in that they are stupid devices and still must be programed by the personel that they are replacing. Most companies see an immediate decrease in rejected manufactured parts.
Hope this gives you some ideas.
