As described above, according to the embodiment of the present invention, the service providing server 300 analyzes the individual status information of the plurality of robots 100 collected through the IoT sensor in real time, And the system abnormality can be detected early and the failure to occur in the future can be predicted and remedied, thereby reducing the loss cost of the plant and improving the stability and reliability of the system.

According to an embodiment of the present invention, when the service providing server 300 analyzes the state of each robot 100, it automatically learns the state change pattern of the robot 100, thereby improving the accuracy of the service .

In addition, according to an embodiment of the present invention, the service providing server 300 collectively monitors a plurality of robots 100 held by a plurality of factories and provides a program capable of checking the status to each factory , The cost for the factories to manage the robot 100 can be reduced and the convenience of the robot 100 can be improved.

It should be understood that the effects of the present invention are not limited to the above effects and include all effects that can be deduced from the detailed description of the present invention or the configuration of the invention described in the claims.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
