A method and a system for the exact positioning an autonomous robot device relative to a stationary structure, such as a DBCS robot in a delivery bin and sorting facility. The robot device is driven from a starting position towards a target position. An absolute positioning sensor is used to monitor the approach to towards an assumed absolute position of the target. Once the target position has entered the field of view of a vision sensor mounted to the robot device, the vision sensor takes an instantaneous image of a visual marker at the target position. The image is evaluated to determine a deviation of an actual location of the target position from the assumed target position. The latter is corrected by adding the deviation to the assumed target position. The robot device then continues and is stopped exactly at the corrected target position.
