iRVision Subtract Offsets (when to answer yes or no)

This video discusses the use of offsets in FANUC robot vision systems, explaining when to accept or decline the "subtract offset" prompt. It begins by explaining that FANUC uses a single frame offset to shift all workpiece-related points, ensuring they move together. The core of the video focuses on the subtract offset function, which mathematically removes the current vision offset, allowing the user to teach a position in the original, unshifted frame. The general rule is to answer "yes" when valid vision data exists. It also covers specific exceptions where answering "no" is necessary, such as when the vision reference position has not been set, or when teaching a part that is already in the robot's gripper, demonstrating a workaround for difficult-to-teach parts.
