Which joint moves the base of the robot?

Explanation:
The thing being tested is which joint controls the robot’s base orientation. The base rotation is handled by the first joint at the very bottom, often called the base or waist joint. This joint provides rotation about the vertical axis, so when it moves, the entire arm and any payload rotate as a unit around the base. The other joints along the arm—often the shoulder, elbow, and wrist—change the relative angles of the arm segments and the position of the end effector, but they don’t rotate the entire base. So the first joint is the one that moves the base.
