Autonomous driving robot and article transport method using the same

An autonomous driving robot comprising:

• a storage unit comprising a housing, which provides a space for storing an article, and a shelf which is provided inside the housing and configured such that the article is loaded on the shelf;
• a manipulator comprising a linear actuator, which is provided inside the housing and extends in a vertical direction, and a selective compliance articulated robot arm (SCARA arm), which is coupled to the linear actuator;
• and
• a transport unit coupled to a bottom surface of the storage unit and configured to move on a floor,
• wherein a plurality of shelves are provided in the storage unit, some of the shelves are provided adjacent to one inner wall of the housing and spaced apart from each other in the vertical direction, and the other shelves are provided adjacent to another inner wall which faces the one inner wall and spaced apart from each other in the vertical direction, and
• the plurality of shelves extend horizontally toward a central axis of the housing, the central axis extending vertically at a center of the housing, and the plurality of shelves do not vertically overlap the central axis of the housing,
• wherein the SCARA arm comprises at least two horizontal joints.

An article transport method comprising:

• transmitting an operation instruction signal from a central control system to an autonomous driving robot, wherein the autonomous driving robot transmits a response signal to the central control system in response to the operation instruction signal;
• moving the autonomous driving robot to a manual port of a stocker;
• and
• starting loading or unloading of an article by the autonomous driving robot,
• wherein the autonomous driving robot comprises:
• a storage unit comprising a housing, which provides a space for storing an article, and a shelf, which is provided inside the housing and on which the article is loaded;
• a manipulator comprising a linear actuator, which is provided inside the housing and extends in a vertical direction, and a selective compliance articulated robot arm (SCARA arm), which is coupled to the linear actuator;
• and
• a transport unit coupled to a bottom surface of the storage unit and configured to move on a floor,
• wherein the SCARA arm comprises at least two horizontal joints.
