The robotic arm is the earliest industrial robot and also the earliest modern robot. It can replace human labor to achieve mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in departments such as mechanical manufacturing, metallurgy, electronics, light industry, and atomic energy. In today's life, with the rapid development of technology, the biggest difference between robotic arms and human arms lies in flexibility and endurance. That is to say, the biggest advantage of a robotic arm is that it can repeatedly perform the same action without feeling tired under normal mechanical conditions! The application of robotic arms will also become increasingly widespread. Robots are a high-tech automatic production equipment developed in recent decades, with the accuracy of operations and the ability to complete tasks in the environment. An important branch of industrial machinery and mobile phones.
