Amazon have patented a robotic device with a conveyor belt.
The electronic commerce company have filed the designs with the US patent office for the clever device, which would assist in the warehouse.
The report reads: "An inventory management system includes a first robotic device and a second robotic device. The first robotic device includes a first conveyor removably docked with a first head of the first robotic device. The second robotic device includes a second conveyor removably docked with a second head of the second robotic device. The first robotic device includes a first conveyor controller that communicates conveyor control signals to a second conveyor controller of the second robotic device. The conveyor control signals specify operations to activate the second motor of the second conveyor."
And Amazon want to use the device as a way to sort inventory items.
They added: "Additionally, configurations of various conveyor segments can enable one or more mobile robotic devices to perform sortation of inventory items. As described further herein, each mobile robotic device may include a rotating head that enables the mobile robotic device to rotate an attached conveyor component along an axis relative to the mobile robotic device. As inventory items travel along one or more conveyor segments, a given mobile robotic device can be controlled or instructed to rotate its attached conveyor component using its rotating head and, as a result, enabling sortation of the inventory item by changing the direction in which the inventory items are moving in the workspace. This can allow the mobile robotic device to align its conveyor attachment to another conveyor attached on another mobile robotic device to perform sortation of inventory items."
