What is the primary purpose of the body axes in a robot?

The primary purpose of the body axes in a robot is to move the end effector to a point in space. The body axes define the robot's coordinate system and give a framework for the robot's movements. They allow the robot to interpret commands about position and orientation, ensuring the end effector - whether it be a gripper, tool, or other implement - can effectively reach its intended destination in the working environment.

This motion capabilities are particularly vital in applications where precision and accuracy are required, such as in manufacturing, assembly, or surgery. The ability to articulate around defined body axes enables the robot to perform complex tasks by adjusting its end effector's placement relative to the objects it interacts with.
