Robotic arms are mechanical devices designed to mimic the movements of a human arm. They consist of joints and links that allow for a range of motion, enabling them to perform tasks such as lifting, assembling, and welding. These arms are commonly used in industries like manufacturing, where precision and efficiency are crucial. Typically controlled by computers, robotic arms can be programmed to carry out repetitive tasks with high accuracy. They often feature sensors and cameras to help them navigate their environment and interact with objects. Applications of robotic arms extend to fields like medicine, where they assist in surgeries, and in automotive assembly lines.
