Robots are very important assets for today’s industry. The use of robots is vital in industrial automation to preserve the quantity and quality of production while introducing flexibility in the manufacturing line. The ever-increasing necessity to introduce new product styles, improve the product quality, and reduce the manufacturing costs has resulted in greater adoption of robotic equipment in various industries. At first, automobile manufacturing companies used robots in their production lines. However, in recent years, other industrial units that produce home appliances, food and pharmaceutical materials, and so on have adopted robotic systems in their production lines. A major reason for the growth in the use of industrial robots in different production lines is their significantly declining cost. In recent years, robot prices have significantly dropped while human labor costs are increasing. Also, robots are becoming more effective, faster, smarter, more accurate, and more flexible.
