What is the purpose of a robotic arm?

The purpose of a robotic arm is to automate tasks that require precision, strength, and repeatability, often in industrial or manufacturing settings. These robotic arms can perform a variety of functions, such as assembling parts, welding, painting, and material handling. They enhance efficiency, reduce human error, and can operate in hazardous environments where human intervention would be risky. Additionally, robotic arms are increasingly used in fields like healthcare and research for surgical assistance and experimentation.
