Industrial automation and robotics play important role in growth of industry. The main criteria in industry are quality and flexibility of the product. In 80’s robot were used to perform tasks like machine tending, material transfer, painting, welding which does not require high accuracy[3]. Considering greater role of robots it was predicted in 90’s that industrial robots will become increasingly vital in applications which require high precision and accuracy. Autonomous robots with sensors are used for accuracy and precision in product which gradually improves the growth of industry. To achieve this precision, robots are programmed for a single task taking sensory information. Real time and highly accurate characteristics of small objects in a fast flowing stream would open new directions for industrial sorting processes. Recent advances in electronics and printed circuit board technology open new perspectives for industrial application in this field.
