In addition, the stacked module robot 1000 according to an embodiment includes a driving module 100 for moving the stacked module robot 1000 , a lift module 300 for lifting an object to transport an object, a traveling module 100 and By including the processor module 200 stacked between the lift modules 300 to control the driving module 100 and the lift module 300, a module having a different configuration is added to the upper part of the lift module 300, or a lift module Because it is easy to replace the 300 or the driving module 100 with another lift module, another driving module, or a module having a different configuration, adaptability and expansion of replacing or changing the function of the robot according to the changed work environment While the performance is improved, the maintenance cost of the modules that are part of the robot is reduced.

That is, assembling, fastening, and coupling between modules is easy, so that adaptability and expandability are improved, and at the same time, maintenance costs are reduced, and the stacked module robot 1000 is provided.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also provided. is within the scope of the
