Which component is essential for coordinating movements in a FANUC system?

The robot controller is the central component in a FANUC system that orchestrates the movements and functions of the robot. It is responsible for interpreting programming instructions, handling motion control, and ensuring that all movements are carried out with precision and timing. The controller processes input from various sensors and executes commands to move the robot effectively through its programmed tasks.

In a FANUC system, all components rely on the controller to function cohesively. The end effector, while vital for performing tasks such as gripping or welding, does not manage movement coordination itself. The teach pendant serves as an interface for operators to program and teach the robot, but it does not control the movements directly. Similarly, while the power supply provides the necessary energy for operation, it does not play a role in coordinating movements. Thus, the robot controller is essential for ensuring that all aspects of the robot's operation are timed and executed properly.
