Abstract:
A method for correcting an actual stop position of an AGV for carrying out a task while the AGV is stopped at a workplace located along a travelling path for the AGV, said method comprising the steps of:a) establishing at least one reference position at the workplace which serves as a reference for determining an actual stop position of the AGV stopped at that workplace on the travelling path;b) ascertaining the reference position of the workplace where the AGV actually stops, based on image data at the actual stop position, and calculating a difference between the reference position and the actual stop position;c) ascertaining whether the difference is within an allowable limit of a predetermined reference value; andd) controlling the AGV to make the difference within the allowable limit of the predetermined reference value if the difference is not within the allowable limit.
