An arm robot, also known as a robotic arm, is a programmable mechanical device designed to perform tasks that typically require human dexterity and precision. These robots are often used in industries such as manufacturing, healthcare, and research for tasks like assembly, welding, surgery, or material handling. Robotic arms are made up of joints and links, mimicking the movements of a human arm, and can be controlled manually or through pre-programmed instructions. Advanced models may include sensors, artificial intelligence, and automation capabilities, allowing for increased precision, speed, and efficiency in performing complex operations.
