A touch screen is a kind of display that enables a user to select a desired menu using a finger or the like or to view an operation currently being executed. At this time, the touch screen is configured to allow the driving unit 100 to check the trajectory that has already passed or remain, or to change the trajectory, or to easily change or control the operating speed or operating time of the driving unit 100. . Such a touch screen is used not only as a screen for inputting commands, but also as a display for displaying images captured by the above-described 3D camera. Of course, it is also used to control a speaker and a sound module to be described later.

Such a touch screen is preferably configured to basically control the driving unit 100, but in a default form, a command or program capable of controlling the function module 300 to be described later is loaded in advance, and the functional module is mounted on the driving unit 100. When the 300 is assembled, the function module 300 is recognized and the program controlling the recognized function module 300 is displayed through the touch screen, so that the function module 300 can be controlled through the touch screen. It is preferable to configure

In particular, the UV module 300b irradiates ultraviolet rays with a UV or UVC lamp to achieve a sterilization action. At this time, the UV module (300b) is supplied with necessary power through a battery installed in the above-described driving unit 100, and configured to operate by controlling the intensity or irradiation time of ultraviolet rays through the above-described control module 200 it is desirable

3. Advertising display module

The advertisement display module 300c is mounted between the driving unit 100 and the control module 200 as shown in FIG. 9 . At this time, since there is a display in front of the advertisement display module 300c, the advertisement image supplied through the above-described control module 200 is shown through the display. Of course, other functional modules 300 may be added above or below the advertisement display module 300c.

In particular, the advertisement display module 300c may display the same advertisement contents one by one on each side by making each side a single billboard, or may control each side to display one advertisement in a panorama shape. In addition, the advertisement display module 300c is preferably configured to be controlled by the control module 200 to control the contents of advertisements, the number of repetitions of advertisement time, and switching to other contents of advertisements.

4. Storage tray module

As shown in FIG. 9, the storage tray module 300d is shown as an example assembled between the above-described drive unit 100 and the control module 200, but between the storage tray module 300d and the drive unit 100 Alternatively, another function module 300 may be additionally assembled between the storage tray module 300d and the control module 200 so that other functions may be used together.

In particular, the storage tray module 300d has a function of simply storing objects, such as serving food or tea to customers sitting at a designated location in a restaurant or tea house, or bringing books returned from a library to a designated location. The driving unit 100 can be moved to a desired location easily, conveniently and accurately by using a function of moving to a desired location, and thus can be conveniently used. In addition, when storing food or tea, the storage tray module 300d is preferably controlled to keep the taste and aroma constant by maintaining an appropriate temperature.

The present invention made as described above is configured so that at least one of various functional modules having different functions can be mounted and used between the drive unit that can move to a desired place and the control module that controls it, so that the service robot according to the present invention It is possible to increase the optimal service effect by selecting the desired function according to the place where it is used. In particular, these functional modules can be configured so that they can be selected and used in various ways according to the functions required for each field, such as for personal use, home use, industrial use, restaurant industry, offline distribution field, medical field, and hotel accommodation. .
