Abstract

A pet robot in a shape of an animal is provided. The pet robot may include a body, a first actuator provided in the body, a rotating body provided in the body and connected to the first actuator to rotate, a second actuator fastened to the rotating body, a thigh portion connected to the second actuator at an upper portion thereof to rotate, a third actuator fastened to a lower portion of the thigh portion, and a calf portion positioned at a lower side of the thigh portion and connected to the third actuator at an upper portion thereof to rotate.

First claim

What is claimed is:

1 . A pet robot in a shape of an animal, the pet robot comprising:
a torso member; a first actuator located in the torso member; a rotating body located in the torso member and connected to the first actuator to rotate about a first axis; a second actuator connected to the rotating body; a thigh member having an upper portion and a lower portion, the upper portion of the thigh member being connected to the second actuator to rotate about a second axis different from the first axis; a third actuator connected to the lower portion of the thigh member; and a calf member having an upper portion and a lower portion, the calf member being located at the lower portion of the thigh member, the upper portion of the calf member being connected to the third actuator to rotate about a third axis different from the second axis.

2 . The pet robot of claim 1 , wherein the thigh member includes an upper receiving portion open toward the rotating body to receive at least a part of the second actuator.

3 . The pet robot of claim 2 , wherein the thigh member includes a lower receiving portion located at a lower side of the upper receiving portion and open toward the torso member or a lower side of the torso member to receive a part of an upper portion of the third actuator.

4 . The pet robot of claim 1 , wherein the first axis is perpendicular to the second axis and parallel to the third axis.

5 . The pet robot of claim 1 , wherein the first axis is located on a same plane as the second axis.

6 . The pet robot of claim 1 , wherein the calf member includes:
a calf body; and a connection portion formed at one side of the calf body, the connection portion being connected to the third actuator.

7 . The pet robot of claim 6 , wherein the calf body is provided with an opening portion open toward a lower side of the torso member.

8 . The pet robot of claim 1 , further comprising a guide body fixed to the torso member, the guide body being located between the first actuator and the rotating body to guide rotation of the rotating body.

9 . The pet robot of claim 8 , wherein the guide body includes a through hole, and
wherein the first actuator is connected to the rotating body via the through hole.

10 . A pet robot in a shape of an animal, the pet robot comprising:
a torso member; a first actuator located in the torso member; a rotating body located in the torso member and connected to the first actuator to rotate about a first axis; a second actuator connected to the rotating body; a thigh member having an upper portion and a lower portion, the upper portion being connected to the second actuator to rotate about a second axis different from the first axis; a third actuator connected to the lower portion of the thigh member; a calf member spaced apart from a lower side of the third actuator; and a link assembly connecting the thigh member to the calf member, the link assembly being configured to rotate the calf member while maintaining the calf member at a predetermined angle with respect to the thigh member as the calf member rotates.

11 . The pet robot of claim 10 , wherein the link assembly includes:
a first link interconnecting the third actuator and the calf member; and a second link interconnecting the thigh member and the calf member, the second link being located behind the first link.

12 . The pet robot of claim 11 , wherein the calf member includes:
a calf body; a link connection located at one side of the calf body and connected to the first link; and a hook portion located at an upper end of the calf body and connected to the second link.

13 . The pet robot of claim 12 , wherein the calf body includes an opening portion configured to be open to a lower end of the torso member.

14 . The pet robot of claim 13 , wherein the calf member further includes a cover configured to cover the opening portion and rotatably connected to the first link.

15 . The pet robot of claim 14 , wherein the cover includes a stopper configured to prevent the second link from being disconnected from the hook portion.

16 . The pet robot of claim 10 , further comprising a foot member rotatably connected to a lower end of the calf member.

17 . The pet robot of claim 11 , wherein the first link includes:
a first link body; a lower connection portion located at a lower side of the first link body and rotatably connected to the calf member; an extension portion extending upward from a front surface of the first link body; and an upper connection portion located at one side of the extension portion and connected to the third actuator.

18 . The pet robot of claim 17 , wherein the first link body includes an opening portion configured to be open to a lower side of the torso member.

19 . A pet robot in a shape of an animal, the pet robot comprising:
a torso member; a first front actuator located in a front portion of the torso member; a front rotating body located in the front portion of the torso member and connected to the first front actuator to rotate about a first front axis; a second front actuator connected to the front rotating body; a front thigh member having an upper portion and a lower portion, the upper portion of the front thigh member being connected to the second front actuator to rotate about a second front axis different from the first front axis; a third front actuator connected to the lower portion of the front thigh member; a front calf member having an upper portion and a lower portion, the front calf member being located at the lower portion of the front thigh member, the upper portion of the front calf member being connected to the third front actuator to rotate about a third front axis different from the second front axis; a first rear actuator located in a rear portion of the torso member; a rear rotating body located in the rear portion of the body and connected to the first rear actuator to rotate about a first rear axis; a second rear actuator connected to the rear rotating body; a rear thigh member having an upper portion and a lower portion, the upper portion connected to the second rear actuator to rotate about a second rear axis different from the first rear axis; a third rear actuator connected to the lower portion of the rear thigh member; a rear calf member spaced apart from a lower side of the third rear actuator; and a link assembly connecting the rear thigh member to the rear calf member, the link assembly being configured to rotate the rear calf member while maintaining the rear calf member at a predetermined angle with respect to the rear thigh member as the rear calf member rotates.

20 . The pet robot of claim 19 , wherein a front to rear distance between the third front actuator and the third rear actuator increases as the torso member is lowered toward a ground.
