A robot arm is a type of mechanical device designed to mimic the movements of a human arm. It consists of joints and links that allow it to perform tasks such as lifting, moving, and manipulating objects. Robot arms are commonly used in industries like manufacturing, where they can assemble products, weld parts, or package goods with precision and speed. These robotic systems can be controlled manually or programmed to operate autonomously. They often use sensors and cameras to detect their environment, enabling them to perform complex tasks. Industrial robots, which include robot arms, have significantly improved efficiency and safety in various applications.
