The invention provides a box type mobile robot. The box type mobile robot comprises a control module, a robot body, universal wheels, driving wheels and a chassis. The chassis comprises a first supporting plate, and the universal wheels and the driving wheels are connected with the chassis. The robot body comprises a door, a second supporting plate, and a storage structural member which forms thestorage space together with the door. The door and the storage structural member are connected with the second supporting plate, and the second supporting plate is connected with the first supportingplate through a first connecting part. The robot body controls the rotating directions and speeds of the driving wheels through the control module so as to control the box type mobile robot to move. The bottom surface of the storage structural member is connected with the second supporting plate through a rotating structure. The storage structural member and the door are closed to form the sealedstorage space, so that the storage space is prevented from being exposed to the outside environment, articles placed in the storage space are prevented from sliding off onto the ground or being takenaway and damaged by people, and the safety of article conveying by the robot is improved.
