a Lidar coupled to a portion in front of the frame assembly; and

a speaker module disposed adjacent to the Lidar,

wherein the lower housing includes:

a groove defined at a front side of the lower housing to extend in a left and right direction, wherein the groove is concavely recessed rearward;

a first opening defined in the groove and exposing the Lidar; and

a second opening located in front of the speaker module.

2 . The driving robot of claim 1 , wherein the driving structure includes:

a caster housing coupled to the frame assembly and having an open bottom; and

a caster positioned in the caster housing,

wherein the speaker is positioned on a top surface of the caster housing.

3 . The driving robot of claim 2 , wherein the second opening is obliquely inclined upward.

4 . The driving robot of claim 3 , further comprising a sound guide inclined surface located at a front surface of the second opening, wherein the sound guide inclined surface is disposed at a lower portion of the groove to be inclined downward in an inward direction.

5 . The driving robot of claim 1 , further comprising:

a third opening defined in a top surface of the groove; and

a dissipation fan formed inside the third opening.

6 . The driving robot of claim 1 , wherein the groove is recessed into a front surface of the lower housing by at least ⅓ of a length in a front and rear direction of the lower housing.

7 . The driving robot of claim 1 , further comprising:

a pair of tray frames coupled to an upper portion of the lower housing and extending upward; and

a tray module coupled to the tray frame.

8 . The driving robot of claim 7 , further comprising a slide basket inserted between the tray module and the lower housing.

9 . The driving robot of claim 8 , further comprising a scratch prevention rib protruding on at least one of a bottom surface of the slide basket and a top surface of the lower housing.

10 . The driving robot of claim 8 , further comprising a camera box protruding from a front portion of a top surface of the lower housing,

wherein the pair of tray frames are located on left and right sides of the slide basket,

wherein the slide basket has a handle formed at a rear surface thereof.

11 . The driving robot of claim 7 , further comprising:

a head frame connecting upper ends of the pair of tray frames to each other; and

an upper basket formed at the head frame.

12 . The driving robot of claim 11 , further comprising a display located on a front surface of the upper basket.

13 . A driving robot comprising:
