Abstract

A robot according to an embodiment of the present invention includes: a main body; a moving rotatably mounted on the main body; a tail protruding outward from the moving housing; a first actuator mounted on the main body, disposed below the moving housing, and configured to allow the moving housing to rotate; a moving link disposed inside the moving housing, the moving link being connected to the tail; and a second actuator disposed inside the moving housing, the second actuator being configured to allow the moving link to rotate.

First claim

1 . A robot comprising:
a main body; a moving housing rotatably mounted on the main body; a tail protruding outward from the moving housing; a first actuator mounted on the main body, disposed below the moving housing, and configured to allow the moving housing to rotate; a moving link disposed inside the moving housing, the moving link being connected to the tail; and a second actuator disposed inside the moving housing, the second actuator being configured to allow the moving link to rotate.

2 . The robot according to claim 1 , wherein a rotation shaft of the first actuator and a rotation shaft of the second actuator are perpendicular to each other.

3 . The robot according to claim 1 , wherein an outer surface of the moving housing comprises a sphere surface having a predetermined curvature.

4 . The robot according to claim 1 , wherein a housing mounting part configured to surround a portion of an outer surface of the moving housing is disposed on the main body.

5 . The robot according to claim 4 , wherein a separation prevention part bent or protruding outward from an edge of the outer surface of the moving housing and disposed inside the housing mounting part is disposed on the moving housing.

6 . The robot according to claim 1 , wherein the moving housing comprises:
a hosing base connected to the first actuator and having an opened top surface; and a housing cap configured to cover an upper side of the housing base.

7 . The robot according to claim 1 , wherein the moving link comprises:
a main link having an arc shape corresponding to that of an inner surface of the moving housing; and a connection link configured to connect the second actuator to the main link.

8 . The robot according to claim 7 , wherein a tail connection part protruding from the main link to the tail and connected to the tail is disposed on the main link.

9 . The robot according to claim 7 , wherein an actuator coupling part which protrudes inward from the inner surface of the moving housing and to which the second actuator is coupled is disposed on the moving housing, and
the actuator coupling part and the connection link are disposed at sides opposite to each other with respect to the second actuator.

10 . The robot according to claim 7 , wherein the main link overlaps the second actuator in a front and rear direction.

11 . The robot according to claim 7 , wherein a slit configured to restrict a rotation range of the tail is defined in the moving housing, and
a slit cover configured to cover the slit is disposed between the moving housing and the main link.

12 . The robot according to claim 11 , wherein the inner surface of the moving housing comprises a guide surface on which the main link and the slit cover are disposed and which has a predetermined curvature.

13 . The robot according to claim 11 , wherein a guide rib configured to guide movement of the main link and the slit cover is disposed on the inner surface of the moving housing.

14 . The robot according to claim 11 , wherein a limiter configured to limit a movement range of the slit cover is disposed on the inner surface of the moving housing.

15 . The robot according to claim 11 , wherein the slit cover has an arc shape that is longer than the main link.

16 . The robot according to claim 11 , wherein an inner slit facing the slit and having an arc shape that is shorter than the slit is defined in the slit cover.

17 . The robot according to claim 1 , further comprising:
an interface disposed inside the moving housing; and a fixed link which is fixed to the main body and to which the interface is coupled.

18 . The robot according to claim 17 , wherein a plurality of through-holes facing the interface are defined in the moving housing.

19 . The robot according to claim 17 , wherein the fixed link comprises:
a fixed part disposed outside the moving housing, the fixed part being fixed to the main body; an interface coupling part which is disposed inside the moving housing and to which the interface is coupled; and a connection part configured to connect the fixed part to the interface coupling part.

20 . The robot according to claim 17 , wherein the interface is disposed above the second actuator, and
the moving link comprises: a main link having an arc shape corresponding to that of an inner surface of the moving housing; and a connection link configured to connect the second actuator to a lower end of the main link, the connection link being disposed below the interface.
