Abstract

The present invention relates to a robot. A robot according to one embodiment of the present invention comprises: a body having a set volume: and a driving module provided in the left region and the right region of the body, respectively, and rotatably connected to the body by a rotation shaft, wherein the driving module comprises: a rotating member connected to the rotating shaft; a first driving part extending from one side of the rotating member slantwise by a first inclination angle with respect to the rotating shaft in a direction away from the rotating shaft; and a second driving part extending from the one side of the rotating member slantwise by a second inclination angle with respect to the rotating shaft in the direction away from the rotating shaft.

First claim

The invention claimed is:

1. A robot comprising:
a body having a set volume; and
traveling modules provided at left and right regions of the body, respectively, and rotatably connected to the body by a rotation shaft,
wherein the traveling module includes:
a rotation member connected to the rotation shaft;
a first traveling portion configured to extend obliquely from one side of the rotation member by a first inclination angle with respect to the rotation shaft in a direction away from the rotation shaft; and
a second traveling portion configured to extend obliquely from one side of the rotation member by a second inclination angle with respect to the rotation shaft in a direction away from the rotation shaft.

2. The robot of claim 1 , wherein the second traveling portion extends in a direction opposite to the first traveling portion based on a longitudinal direction of the rotation shaft.

3. The robot of claim 1 , wherein the second traveling portion is configured to be longer than the first traveling portion.

4. The robot of claim 1 , wherein the rotation shaft is configured obliquely downward by a set angle with respect to a plane including a front-rear direction and a left-right direction.

5. The robot of claim 1 , wherein the second traveling portion is configured to extend on a plane including a longitudinal direction of the rotation shaft and a longitudinal direction of the first traveling portion.

6. The robot of claim 1 , wherein the rotation shaft is configured obliquely downward by 45° with respect to a plane including a front-rear direction and a left-right direction.

7. The robot of claim 1 , wherein the first inclination angle is 45° or less.

8. The robot of claim 1 , wherein the second inclination angle is 45° or less.

9. The robot of claim 1 , wherein the traveling module includes:
a front traveling module located on left and right sides of a front region of the body; and
a rear traveling module located on left and right sides of a rear region of the body.

10. The robot of claim 9 , further comprising:
a front driving shaft having both ends respectively connected to the rotation shaft to which the front traveling module is connected; and
a rear driving shaft having both ends respectively connected to the rotation shaft to which the rear traveling module is connected.

11. The robot of claim 1 , wherein a first traveling wheel is provided on a lower end portion of the first traveling portion, and a second traveling wheel is provided on a lower end portion of the second traveling portion.

12. The robot of claim 1 , further comprising:
a fan provided fixedly to the body to generate airflow in an upward direction from a bottom.

13. The robot of claim 1 , further comprising:
a sensor configured to detect whether an obstacle exists against traveling.
