Which mode allows a user to control a FANUC robot with precise movements?

JOG mode allows a user to control a FANUC robot with precise movements by enabling manual movement of the robot's joints or tool in real-time. This mode is particularly useful for operators who need to touch up positions, perform detailed work, or modify the robot's path prior to executing automated tasks. In JOG mode, users can move the robot in small increments, adjusting the speed and direction as needed, providing the granularity required for precise control.

Understanding the purpose of the other modes can provide additional context. Automatic mode is primarily focused on running pre-programmed tasks and sequences without manual intervention. Program mode is used for creating and editing the robot's movement programs but does not allow for real-time control of the robot's movements. Maintenance mode is designed for troubleshooting and maintaining the robot's systems rather than for executing precise movement tasks. Thus, JOG mode stands out as the most appropriate choice for fine control over the robot's movements.
