Robotics is a field concerned with the agile connection of perception to action. Nowadays, artificial intelligence (AI) is used in every industry to automate applications throughout the product line to save time and money. Robots are now used to handle the most tedious and dangerous manufacturing applications to save time and keep the workers motivated. On the other hand, robots also reduce waste and increase productivity with continuous precision.
A Robotic Arm is a kind of mechanical arm, usually programmable, which performs the same function as that of the human arm. The robotic arm is made up of seven metal segments, joined by six joints. A robotic arm is controlled by a computer which links the joints attached to the arm.
On the basis of their applications, robotic arms can be differentiated into different types, such as the Cartesian Robot Arms, used to pick up and place an object, assembly operations, handle machine tools, and arc welding; Cylindrical Robot Arms, used in assembly operations, handle machine tools, spot welding, and die-casting; Polar Robot Arms, used to handle machine tools, spot welding, die-casting, gas welding, and arc welding; SCARA Robot Arms, used to pick up and place an object, assembly operations, and handle machine tools; and Articulated Robot Arms, used to assembly operations, die-casting, gas welding, arc welding, and spray painting.
Robotic arms are designed based on their applications. Hence, every application will have a different requirement. In the field of medical science, robotic arms are used in operations. Furthermore, robotic arms are used as food packers in the food processing industry, and in the field of automotive, robotic arms are used in assembling vehicles.
A robotic arm can do all the work that a human arm does. A robotic arm is highly evolved in industrial automation for the manufacturing of vehicles to paint them. Accuracy and strength in robotic arms come only at the cost of weight, complexity, and cost. Hence, lightweight robotic arms could not do tasks involving heavy strength. However, robots are energy inefficient that needs to be tackled with technology. Future-driven robots are the humanoid robots that interact with humans and help them in their day-to-day tasks. In addition, autonomous vehicles will become a trend in the near future.
China to Be the Biggest Consumer of the Industry
Robotic arms have come a long way since they were first introduced in China in 1951. Since then, various commendations or advancements have been made in the robotics industry. Being the largest market for robotic arms, China accounts for one-third of the global industrial robots demand. The market volume of China's industrial robots was USD 4.2 billion in 2017 and is expected to increase to USD 5.9 billion in 2020. With currently holding 30% of the global sales market share, China is expected to manufacture 1,50,000 industrial robots units by 2020 and have 950,300 industrial robots units in operation. Robotic arms are typically large, immobile, expensive, and too dangerous to deploy in the vicinity of human workers. Despite the exceptional uses, robotic arms have a room for improvement. Robotic arms are powerful, precise, efficient, and can handle heavy workloads with minimal downtime.
