A robotic 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. Robotic arms are commonly used in industries like manufacturing, where they can assemble products, weld parts, or package goods. These devices can be controlled manually or programmed to operate autonomously. They often use sensors and cameras to enhance their precision and efficiency. Robotic arms are also found in fields like medicine, where they assist in surgeries, and in research, where they help with experiments and data collection.
