A robot arm is an electromechanical device that is designed to mimic the movements of a human arm. It consists of a series of joints that enable it to move in a wide range of directions and a manipulator (or end effector) that can grasp, move, and manipulate objects.

Robot arms are commonly used in industrial automation and manufacturing, where they are programmed to perform repetitive tasks such as assembly, welding, painting, or material handling. They are typically controlled by a computer or a programmable logic controller (PLC) and can be customized to perform a variety of tasks depending on the needs of the application.

Robot arms can be operated manually by a human operator or programmed to operate autonomously. They are often equipped with sensors and cameras to help them detect and adapt to their surroundings, and they can be programmed to follow a predefined sequence of movements or to operate dynamically in response to changes in their environment.

The joints of a robot arm are typically driven by electric motors or hydraulic actuators, which provide the necessary torque and force to move the arm. The manipulator (or end effector) is often equipped with specialized grippers, suction cups, or other tools that enable it to grasp and manipulate objects in a precise and controlled manner.
