Which component is tasked with the actual movements of a robot?

The manipulator is the component responsible for the actual movements of a robot. It serves as the robotic arm or limb, allowing the robot to reach, move, and perform tasks in its environment. The manipulator is equipped with joints and segments that work together to achieve a wide range of motion, which is essential for executing specific tasks such as lifting, turning, and positioning.

This makes it distinct from other components. The programming device, for instance, is responsible for inputting instructions into the system, while the end effector is the tool or gripper attached to the end of the manipulator that interacts with the environment to perform specific tasks like picking up items or applying pressure. Lastly, the controller manages the robot's operations and executes commands, but it does not physically perform the movements itself. Thus, the manipulator is key to the robot's ability to achieve physical movement and interact with the surrounding space.
