A storage system comprising rails forming a grid pattern comprising a plurality of grid spaces and a plurality of stacks of containers located beneath the rails, arranged such that each stack is located within a footprint of a single grid space. At least one transporting device is arranged to selectively move laterally above the stacks on the rails and to transport a container. A picking station is arranged to receive the container transported by the at least one transporting device. The storage system includes a control unit for operation with a robot system comprising a sensor unit, the robot system arranged to grasp an item from a first container. The control unit comprises a verification unit arranged to: receive identifying information of an item expected to be in the first container; receive information from the sensor unit indicative of a dynamics property induced by motion of the grasped item relative to the sensor unit; and verify whether the grasped item matches the item expected to be in the first container based on the received identifying information and dynamics property information. The control unit also comprises a command unit arranged to, in response to the verification unit failing to verify the grasped item, command the robot system to perform a predetermined manoeuvre for the verification unit to verify the grasped item based on further dynamics property information corresponding to the predetermined manoeuvre.
