Further, the carrying robot can send out alarm information when the goods taking command is executed but the goods box cannot be taken, and when the goods storage command is executed but the target storage space is occupied.
The invention also provides a method for carrying goods by the robot, which comprises the following steps:
the carrying robot autonomously moves to the front of a target goods shelf according to a goods taking instruction, the goods box transmission unit acquires a goods box from one goods box storage space of the goods shelf specified according to the goods taking instruction and then transmits the goods box to the other goods box storage space of the goods box storage unit specified according to the goods taking instruction;
or,
the transfer robot autonomously moves to the front of the target pallet according to the stock order, and the container transfer unit takes one container from one of the container storage spaces of the container storage unit specified according to the stock order and then transfers it to the other of the container storage spaces of the pallet specified according to the stock order.
Further, the container storage unit can store a plurality of containers on different height levels; the pallet is capable of storing multiple containers at different height levels.
Further, containers on different height layers of the container storage unit can be stored on different height layers of the goods shelf through the container conveying unit; the containers on the layers with different heights of the goods shelf can be stored on the layers with different heights of the container storage unit through the container conveying unit.
Further, the robot is capable of placing a container of a level on the container storage unit to another level on the container storage unit.
Further, the finishing function can be performed while traveling or while stopping.
Further, the transfer robot can store the containers on any layer of the pallet to a designated layer of the container storage unit by the container conveying unit, and then store the containers on another layer of the same pallet to another designated layer of the container storage unit by the container conveying unit.
Further, the transfer robot can store the containers of any layer on the pallet to a designated layer of the container storage unit through the container conveying unit, and then store the containers of any layer on another pallet to the designated layer of the container storage unit through the container conveying unit.
Further, the transfer robot can store the containers stored in any layer on the container storage unit to a designated layer on the pallet through the container conveying unit, and then store the containers in another layer on the container storage unit to another designated layer on the same pallet through the container conveying unit.
