In FANUC robots, what does the term ‘force control’ refer to?

Force control in FANUC robots refers to the ability to sense and control the amount of force applied during operations. This feature is crucial when robots interact with their environment, particularly in tasks involving delicate or variable materials. By measuring the force exerted by the robotic arm, the system can adjust its movements in real-time to apply the appropriate amount of pressure. This capability enhances precision and safety in handling tasks, such as assembly, machining, or collaborative operations with human workers.

In contrast, the other options focus on different aspects of robotic functionality. While the ability to perform multiple tasks simultaneously is important for efficiency, it does not specifically relate to how force is controlled during operations. Similarly, handling heavier loads pertains to the robot's structural capacity rather than its force management capabilities. Lastly, adjusting speed based on object weight is a separate function that deals with dynamics and motion rather than direct force application. Thus, the focus on force management distinguishes this particular capability as essential for certain applications where precision and sensitivity are required.
