Abstract

According to an embodiment of the present disclosure, a service module may include a main body having an accommodation space in which an article is accommodated, a slam module installed on an upper portion of the main body, and a wire guide groove defined in the main body to guide an electric wire connected to the slam module. The slam module may has an upper end having a height lower than a height of a top surface of the main body.

First claim

The invention claimed is:

1. A service module, comprising:
a main body having an accommodation space configured to receive an article therein, the main body having an upper portion including a top surface of the main body;
at least one Simultaneous Localization and Mapping (slam) module located at the upper portion of the main body, the upper end of the at least one slam module being located lower than the top surface of the main body by a predetermined gap;
an electric wire having a first end connected to the at least one slam module; and
a wire guide groove located in the main body to guide the electric wire connected to the at least one slam module,
wherein the upper portion of the main body includes a peripheral surface extending from the top surface, and a recess located at a boundary between the top surface and the peripheral surface,
wherein the at least one slam module is received in the recess,
wherein the recess includes:
an inclined portion having an opening, the inclined portion configured to face in an inclined direction between a horizontally outward direction and a vertically upward direction of the main body, the inclined portion having a front edge and a rear edge;
a front extension connected to the front edge of the inclined portion and connected to the top surface and a peripheral surface extending from the top surface of the main body; and
a rear extension connected to the rear edge of the inclined portion and connected to the top surface and the peripheral surface of the main body, the rear extension being spaced apart from the front extension, and

wherein the front extension and the rear extension extend at an increasing angle from the inclined portion towards the top surface of the main body.

2. The service module of claim 1 , wherein the at least one slam module is oriented to face in an inclined direction between a horizontally outward direction and a vertically upward direction of the main body.

3. The service module of claim 1 , further comprising a control box located in the main body, the control box being electrically connected to the at least one slam module.

4. The service module of claim 1 , wherein the main body includes:
an outer body having a slam module mounting portion on which the at least one slam module is mounted; and
an inner cover configured to cover the slam module mounting portion.

5. The service module of claim 4 , wherein the inner cover has a slam module avoiding portion configured to avoid interference with the at least one slam module when the inner cover is connected to the outer body.

6. The service module of claim 4 , wherein the at least one slam module includes a pair of slam modules spaced apart on opposite sides of the main body, and
wherein the outer body includes:
a front body having a pair of side edges; and
a pair of side bodies extending rearward from the pair of side edges of the front body, each side body having a slam module mounting body to receive a corresponding slam module of the pair of slam modules.

7. The service module of claim 4 , further comprising a control box electrically connected to the at least one slam module,
wherein the outer body has a control box mounting portion on which the control box is mounted.

8. The service module of claim 7 , wherein the wire guide groove is located in the outer body, and
wherein the wire guide groove is in communication with the slam module mounting portion and the control box mounting portion.

9. The service module of claim 8 , wherein the inner cover is configured to cover the control box mounting portion and the wire guide groove.

10. The service module of claim 7 , wherein the outer body includes:
a wire guide portion extending downward from the control box mounting portion; and
a lower recess recessed rearward from a front portion of the outer body, the lower recess being in communication with the wire guide portion.

11. The service module of claim 10 , wherein the outer body includes:
a bottom surface; and
a connecting groove located in the bottom surface, the connecting groove being in communication with the wire guide portion and the lower recess.

12. A mobile robot, comprising:
a mobile module including a driver; and
a service module of detachably mounted on the mobile module, the service module including:
a main body having an accommodation space configured to receive an article therein, the main body having an upper portion including a top surface of the main body;
at least one Simultaneous Localization and Mapping (slam) module located at the upper portion of the main body, the upper end of the at least one slam module being located lower than the top surface of the main body by a predetermined gap;
an electric wire having a first end connected to the at least one slam module and a second end connected to an interior of the mobile module; and
a wire guide groove located in the main body to guide the electric wire connected to the at least one slam module,
wherein the mobile module includes:
a body provided with the driver;
a vertically extending display located at an upper side of a front portion of the body, the display located forwardly of the service module; and
a module support plate located above the body to support the service module from below,

wherein the main body includes:
a wire guide portion configured to guide the electric wire connected to the interior of the main body; and
a lower recess recessed rearward from a front portion of the main body, the lower recess being in communication with the wire guide portion, and

wherein the display includes:
a lower opening portion configured to communicate with an interior of the body;
a rear opening portion configured to communicate with the lower recess; and
a shutter configured to open and close the rear opening portion.

13. The mobile robot of claim 12 , wherein the main body has a guide groove configured to receive at least a portion of the display therein.

14. The mobile robot of claim 12 , wherein the display includes a shutter guide configured to guide raising and lowering movements of the shutter.
