Shuttle robots (107) are used that are suitable for moving trolleys (106, 106′) under the control of a monitoring and control unit (190) for handling objects so as to move them from a collection point (110) to a palletizing station (151) remote from the collection point, the shuttle robots being autonomously movable and being suitable for hitching to and unhitching from the trolleys, the monitoring and control unit controls the shuttle robots so that they move the objects on trolleys from the collection point to a buffer storage zone (141) where the articles on the trolleys are grouped together into batches of articles for palletizing, and the monitoring and control unit controls the shuttle robots so that they take the objects on trolleys grouped together in batches from the buffer storage zone and move them in sequence to the palletizing station.
