True or False: For accurate movement to a recorded position, only the X axis position needs to be known.

• A. True
• B. False
• C. Not enough info
• D. Depends on axis

Answer: (B)

Reaching a stored position means hitting a specific pose in space, and that pose is defined by more than just one coordinate. A recorded position on a FANUC robot is typically given by X, Y, Z positions plus orientation (the rotation about each axis, often referred to as A, B, C). The robot uses all of these values to determine exactly where the end effector should be and how it should be aligned. If you only know the X coordinate, you could end up at the right X value but with the wrong Y and Z, or you could be misoriented, so you wouldn’t truly reach the intended pose. That’s why the statement is false. In practice, the full set of coordinates (and orientation if required) is necessary to guarantee an accurate move to a recorded position.
