"Fully automatic" refers to a system or device that operates independently without the need for manual intervention. This means that once the device is set up, it can perform its functions automatically, completing tasks on its own. Examples include fully automatic washing machines that wash, rinse, and spin clothes without user input after the initial settings are chosen. In various industries, fully automatic systems enhance efficiency and productivity. For instance, in manufacturing, fully automatic assembly lines can produce goods with minimal human oversight, reducing labor costs and increasing output. These systems rely on advanced technology, such as sensors and robotics, to ensure smooth operation.
