What is the primary purpose of a robotic arm?

The primary purpose of a robotic arm is to mimic the movements of a human arm. Robotic arms are designed to replicate the dexterity and functionality of human limbs, enabling them to perform tasks that require precision and flexibility. They are equipped with various joints and actuators that allow them to move in multiple directions, much like a human arm. This mimicking capability enables robotic arms to engage in complex tasks such as assembly, welding, painting, and material handling, which are essential in various industrial and research applications.

By imitating human arm movements, robotic arms can adapt to different tasks and environments, making them highly versatile tools in automation and robotics. This feature is central to their design and functional role in both manufacturing and service robot applications.
