If a tool offset is not correctly applied, what is the most likely result?

• A. The robot will never operate again.
• B. It only affects telemetry, not pose.
• C. The base frame will automatically adjust to compensate.
• D. If not applied correctly, the end-effector pose will be inaccurate.

Answer: (D)

Tool offset defines how the tool tip sits relative to the robot’s flange and is used in calculating the end-effector pose. If that offset isn’t applied correctly, every commanded position and orientation is built from the wrong reference, so the end-effector ends up in the wrong place and orientation. In practice, that means the robot will not reach the intended target accurately, which is why the end-effector pose becomes inaccurate. Telemetry isn’t the only thing affected, and the base frame won’t automatically fix this by itself.
