a method for correcting an actual stop position of an agv for carrying out a task while stopped along a travelling path includes the steps of : a ) establishing at least one reference position as a basis for determining an actual stop position of the agv on the travelling path ; b ) ascertaining the reference position where the agv actually stops , based on image data of the actual stop position , and calculating the 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 ; and d ) controlling the agv to make the difference within the allowable limit of the reference value if the difference is not within the allowable limit . with this method , and an apparatus therefor , the actual stop position of the agv on the travelling path can be easily determined , and the actual stop position of the vehicle body or the manipulator of the agv can be easily corrected to be located at respective predetermined correct working positions .
