What is the measurement unit for the World Major Axes?

The correct unit of measurement for the World Major Axes is millimeters. This is because robot coordinate systems often operate in metric units, and in many robotic applications, precision is crucial. Millimeters provide a smaller unit of measurement that allows for detailed positioning and movement of the robot in its operational environment.

This metric system standardization helps in maintaining consistency and accuracy across various robotic components and systems. Other options, such as inches or centimeters, are less commonly used in industrial robotics, particularly with FANUC robots, which predominantly utilize millimeters for their dimensional specifications and programming. Degrees, while important for angles and rotations, are not relevant when discussing linear measurements like the World Major Axes. Therefore, understanding the emphasis on millimeters aids in grasping how precise movements and distances are calculated and controlled within robotic systems.
