What is the primary purpose of a FANUC robot controller?

The primary purpose of a FANUC robot controller is to manage the robot's operations. This includes coordinating the robot's movements, processing inputs from various sensors, executing programmed instructions, and ensuring that the robot operates safely and efficiently. The controller acts as the brain of the robot, enabling it to perform tasks such as welding, assembly, or painting with precision and reliability.

While other aspects such as appearance, power supply, and weight may be important in the overall design or functionality of the robot, they are not the main roles of the controller. The focus of a controller is squarely on operational management, ensuring that the robot can carry out its designated tasks effectively within an automation context.
