After the robot 300 jacks up the shelf, the rotation mechanism may complete the rotation of the robot 300 while the direction of the shelf remains the same.

The working steps of the cargo transportation device of the present application are as follows:

1. the robot 300 receives the instruction, drills under the formulated unpowered goods shelf 100 under the control of the navigation module, and the jacking module 31 on the robot 300 jacks up the unpowered goods shelf 100, so that the action that the unpowered goods shelf 100 is carried on the mobile robot 300 is completed.
