At this time, the control signal may include a signal related to the operation of the carrying robot 10, such as setting the path of the carrying robot 10, controlling the operation of the carrying robot 10, and the like. The external controller 1 can confirm the information of the carrying robot 10 in addition to inputting the above signals. For example, the information of the carrying robot 10 includes information on the running of the carrying robot 10 such as the traveling distance and the traveling path of the carrying robot 10, the weight of the object loaded on the carrying robot 10, Such as the number of objects loaded on the door 10). At this time, the external controller 1 can recognize the information of the carrier robot 10 as described above by the user's operation or automatically by voice, image, or the like to the user.

When the drive signal is inputted from the external controller 1, the carrying robot 10 can start the operation. In this case, the driving signal may be transmitted to at least one of the traveling robot 300 and the mobile robot 200. When the drive signal is transmitted to the traveling robot 300, the traveling robot communication module 360 may transmit the driving signal to the traveling robot controller 350. The traveling robot control unit 350 can drive the wheel driving unit 330 by controlling the traveling robot electric supply unit 370 in accordance with the driving signal. In this case, the wheel driving unit 330 operates to drive the wheel (not shown), and the carrying robot 10 can start running. In this case, the traveling robot control unit 350 can control the wheel driving unit 330 to move the traveling robot 300 along a predetermined path. The traveling robot control unit 350 controls the wheel driving unit 330 according to the external environment based on the signal measured in the LR 340 so that the carrying robot 10 can be prevented from colliding with the external obstacle have. In another embodiment, the traveling robot controller 350 may determine the path based on the external environment measured in the LAD 340 in addition to the predetermined path. At this time, the traveling robot controller 350 may set the path based on the data stored in the external environment measured by the LR 340 and then operated again.

The storage unit (not shown) and the mobile robot 200 can move together with the traveling robot 300 when the traveling robot 300 moves as described above. At this time, the mobile robot 200 is located at the bottom of the storage unit, and can move to the opened part of the storage unit when the drive signal is input. In another embodiment, the mobile robot 200 may be disposed at the open portion of the storage unit when the drive signal is input. Hereinafter, for convenience of explanation, the case where the mobile robot 200 is disposed at the opening portion of the storage unit will be described in detail.

When the traveling robot 300 moves as described above, the user can store the goods in the storage unit. Specifically, when an object is stored in the storage unit, the mobile robot 200 may be disposed below the second sub-sensing unit 520. At this time, when the object is stored in the storage unit, the object can be placed on one side of the mobile robot 200. In this case, the object is overlapped with the storage portion where the first sub sensing portion 510 is disposed or overlapped with the storage portion where the first sub sensing portion 510 and the second sub sensing portion 520 are disposed Respectively. In addition, the object may be disposed so as to overlap with the storage portion where the second sub sensing portion 520 is disposed. Hereinafter, for convenience of explanation, the case where the object is disposed so as to overlap with the storage portion where the first sub sensing portion 510 and the second sub sensing portion 520 are disposed will be described in detail.

When the object is loaded on the mobile robot 200 as described above, the light emitted from the light emitting unit of the first sub sensing unit 510 and the light emitting unit of the second sub sensing unit 520 is reflected on the object, And can be detected by the light receiving unit of the sensing unit 510 and the light receiving unit of the second sub sensing unit 520. In this case, the first sub-sensing unit 510 and the second sub-sensing unit 520 can transmit the sensed result to the outside through the transmitting unit 600. [

At this time, the mobile robot communication module 280 can receive the signal transmitted from the sending unit 600. [ The mobile robot controller 270 may determine that the mobile robot 200 is loaded with the object based on the above signals.

The mobile robot controller 270 includes a first driving force generating unit 221a, a second driving force generating unit 222a, a third driving force generating unit 223a, and a fourth driving force generating unit 224a, So that the mobile robot 200 can be moved to the bottom surface of the storage unit. At this time, the mobile robot controller 270 can simultaneously maintain the equilibrium of the mobile robot 200 by controlling the first driving force generating unit 221a to the fourth driving force generating unit 224a at the same time.

When the mobile robot 200 moves as described above, one side of the object moves to the storage portion where the second sub sensing portion 520 is disposed through the storage portion on which the first sub sensing portion 510 is disposed . In this case, a signal may not be generated in the first sub-sensing unit 510 or a different signal may be generated and may be transmitted to the mobile robot controller 270 through the transmitting unit 600 and the mobile robot communication module 280 have. In addition, since the same signal is detected in the second sub-sensing unit 520, the signal can be transmitted to the mobile robot controller 270 through the transmitter 600 and the mobile robot communication module 280. At this time, the mobile robot control unit 270 can continuously move the mobile robot 200 within the storage unit by controlling the first driving force generation unit 221a to the fourth driving force generation unit 224a .

When the mobile robot 200 continuously moves, one side of the object can pass through the receiving part where the second sub sensing part 520 is disposed. In this case, the second sub-sensing unit 520 may generate no signal or generate a signal different from the signal. These contents can be transmitted to the mobile robot controller 270 through the sending unit 600 and the mobile robot communication module 280. The mobile robot controller 270 may determine that the loading of the object has been completed and stop the position of the mobile robot 200. [ At this time, the mobile robot controller 270 may stop the operation of the first driving force generating unit 221a to the fourth driving force generating unit 224a, thereby fixing the mobile robot 200 in the receiving unit.

The above operation can be continuously performed when the object is loaded on the mobile robot 200. At this time, as the object is loaded, the mobile robot 200 can continuously move to the bottom of the storage unit, and the storage unit can store and store a plurality of objects.

While the object is being loaded, the mobile robot 200 can reach the bottom of the storage unit. In this case, the mobile robot 200 may contact the first sensing unit 400. When the first sensing unit 400 and the mobile robot 200 are in contact with each other, a signal may be generated in the first sensing unit 400 have. The signal generated by the first sensing unit 400 may be transmitted to the traveling robot controller 350 through the transmitting unit 600 and the traveling robot communication module 360. [

The traveling robot controller 350 may determine that the receiver is full of objects when the first sensing unit 400 detects a signal. The traveling robot control unit 350 can control the wheel driving unit 330 to move the traveling robot 300. [ At this time, the traveling robot control unit 350 may control the wheel driving unit 330 to move the traveling robot 300 to a preset point. As another embodiment, the traveling robot control unit 350 may transmit the information that the object is full to the storage unit by the external controller 1 and move the traveling robot 300 to the position input from the external controller 1 It is possible. Hereinafter, for convenience of explanation, the traveling robot control unit 350 controls the wheel driving unit 330 to move the traveling robot 300 to a predetermined position.

When the traveling robot 300 arrives at a predetermined point, the user can take out the article stored in the storage unit to the outside. At this time, the user can stop the operation of the carrying robot 10 through the external controller 1 or stop the operation of the carrying robot 10 through the switch provided separately to the carrying robot 10. [

When all the objects of the storage portion are drawn out to the outside, the user can operate the carrying robot 10 again through the external controller 1. [ At this time, the mobile robot control unit 270 can move the mobile robot 200 to the entrance side of the opening portion of the storage unit 100. [ Specifically, the mobile robot controller 270 may control the first driving force generating unit 221a to the fourth driving force generating unit 224a to separate the mobile robot 200 from the bottom surface of the storage unit. In this case, the mobile robot 200 can linearly move along the inner surface of the storage unit.

When the mobile robot 200 moves as described above and the mobile robot 200 is detected by the first and second sub sensing units 510 and 520, the mobile robot 200 may stop. The mobile robot controller 270 can adjust the position of the mobile robot 200 so that the support part (not shown) of the mobile robot 200 is disposed below the storage part where the second sub sensing part 520 is disposed have.

When the above operation is completed, the traveling robot control unit 350 can control the traveling robot 300 to autonomously travel as described above. At this time, when the object is loaded on the storage unit, the carrying robot 10 can repeat the above-described operation.

Accordingly, the carrying robot 10 can store a plurality of objects, temporarily store them, and transfer them to a desired position. The carrying robot 10 can transfer the object to a desired place without an operation of the user through the autonomous running. In addition, the carrying robot 10 can move a large number of objects at the same time by moving the inside of the storage unit by the operation of the mobile robot 200 according to the loading of the objects.
