1. A carriage robot comprising:
a robot arm being configured to transport a plurality of containers;
a robot hand connected to an end of the robot arm, the robot hand being configured to support a first container having a lower surface and a first size among the containers; and
a gripper protruded downwardly from a body of the robot hand to be provided under the robot hand, the gripper being configured to grip a second container having a second size different from the first size,
wherein the robot hand supports the first container with entirely contacting the lower surface of the first container and the gripper grips the second container such that the carriage robot is configured to simultaneously transport the first container and the second container by moving the robot hand,
wherein the robot arm has at least a first arm, a second arm and a third arm configured as stacked arms, and the third arm, which is an uppermost arm included in the robot arm, has a thickness matching a height of the second container, and
wherein when the gripper grips the second container, the second arm, positioned under the third arm as the uppermost arm, makes contact with the lower surface of the second container and the second arm supports the second container causing the second container to be suppressed from falling while the carriage robot transports the second container.
