What components are listed as the robot's minor axes?

In the context of FANUC robots, the minor axes refer to the joints that primarily contribute to the robot's ability to manipulate objects and adjust their orientation. The configuration of these axes is typically designated based on their function and structural role in the robotic system.

The correct selection identifies J4, J5, and J6 as the robot's minor axes. These joints are responsible for finer movements and adjustments to the end effector's position and orientation. J4 usually provides wrist rotation, while J5 and J6 enable pitch and yaw adjustments, respectively, allowing for intricate motion and flexibility in manipulating items.

In contrast, the other choices either include major axes or combinations of joints that do not facilitate the same level of fine control. J1, for example, is often a base rotation joint, which is generally classified as a major axis, focusing on broader movements rather than the nuanced adjustments characteristic of the minor axes. Understanding this distinction is essential in grasping how various axes contribute to a robot's operational capabilities.
