A polishing device for a metal conveyor belt suitable for an automatic conveyor line includes a holding pillar with one end fixedly provided with a bearing head, a supporting carriage fixedly connected to the bearing head, assembly supporting frames, an assembly sliding column, a polishing supporting shaft and locking mechanism. A bottom end of the holding pillar is provided with a barrier protection assembly. Both ends of the supporting carriage are respectively provided with a reciprocating assembly and two assembly supporting frames. Opposite side surfaces of the two assembly supporting frames are respectively rotatably connected with a rotating seats. Both ends of the assembly sliding column are respectively fixedly installed and in transmission connection with two rotating seats. Both ends of the assembly sliding column are respectively in transmission connection with the reciprocating assembly. The polishing supporting shaft is in transmission connection with the assembly sliding column.

A monitoring device can include one or more sensors, and a processor, operably connected to the one or more sensors, configured to execute computer-readable instructions that cause the processor to perform operations including detecting sensor data from the one or more sensors. The sensor data can be collected as the monitoring device is in transit in a transport system for delivery items. The operations can also include detecting a malfunctioning component in the transport system based on the sensor data, and transmitting a maintenance indicator to a control system of the transport system, wherein the maintenance indicator identifies the malfunctioning component.

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