A manipulator arm, often referred to as a robotic arm, is a type of mechanical arm that is controlled by a computer or other automated means. These arms are typically used for tasks that are repetitive, dangerous, or require a high degree of precision. They are a fundamental component of industrial robotics and are found in a wide variety of applications, including manufacturing, assembly, welding, painting, and material handling.

Manipulator arms can vary greatly in size and complexity, from small, delicate arms used in laboratory settings to large, heavy-duty arms capable of lifting several tons. They are often described by their degrees of freedom, which refer to the number of independent movements the arm can make. A higher number of degrees of freedom generally allows for more versatile and complex movements.

The basic structure of a manipulator arm usually consists of a series of links connected by joints. These joints, which can be revolute (rotational) or prismatic (linear), allow the arm to move in different directions. At the end of the arm is an end-effector, which is a tool or gripper designed to perform a specific task. Examples of end-effectors include grippers, welding torches, drills, and paint sprayers.

Control systems for manipulator arms range from simple programmed sequences to sophisticated artificial intelligence algorithms. These systems enable the arm to execute pre-defined movements, respond to sensor inputs, and even adapt to changing environments. The development of manipulator arms has been a key driver in the advancement of automation and has significantly impacted industrial productivity and safety.
