Method and system (10) for transporting products (2). A conveyor surface (1) is moving at a conveyor velocity (VI). Products (2) are provided on the conveyor surface (1) in a measurement zone (M). The products (2) move through the measurement zone (M) with a product velocity (V2) that is at least initially different than the conveyor velocity (VI). A contact between the products (2) and the relatively moving conveyor surface (1) causes the products (2) to accelerate or decelerate (a) in the measurement zone (M) depending on a kinetic friction coefficient (k) there between. A control signal (S) is indicative of the acceleration or deceleration (a) of the products (2) in the measurement zone (M). The kinetic friction coefficient (k) is controlled based on the control signal (S) to keep the acceleration or deceleration (a) within a predetermined threshold range.

A robotic service device for a robotic picking system grid. The robotic service device can be configured for driving to any location on the grid in order to restart malfunctioning robotic load handling devices or to perform maintenance operations or cleaning in situ. Additionally, the service device may be used to rescue robotic load handling devices operational in the picking system. The robotic service device can include a releasable docking mechanism to enable it to dock and latch on to malfunctioning load handling devices. The service device can also be provided with a cleaning device and camera device to enable a condition of a grid and other robotic devices to be monitored.

A device for discharging particulate material, for example powder material, granules or capsules, or in general free-flowing material, such as adhesive material, on a substrate moving along a conveying direction, includes at least one drum rotor having at least one helical track carrying the material to be discharged. The drum rotor is arranged adjacent to the moving substrate, with its axis substantially parallel to the conveying direction so that the portion of the at least one helical track which is closest to the substrate moves in the conveying direction during rotation of the drum rotor and discharges the material carried thereby on the substrate.
