Robot having flexible outer skin
A robot includes a trunk portion frame (functioning as a “base portion”), a head portion frame (functioning as a “first movable portion”) supported by the trunk portion frame, a flexible outer skin provided in such a way as to come into contact with the head portion frame and cover the trunk portion frame, and a pair of arm portions (functioning as a “second movable portion”), provided in contact with the outer skin, whose relative displacement with respect to the trunk portion frame changes in accompaniment to a displacement of the outer skin that accords with an operation of the head portion frame.
1. A robot, comprising:
a base portion;
a first movable portion supported by the base portion;
a flexible outer skin provided in such a way as to come into contact with the first movable portion and cover the base portion, wherein movement of the first moveable portion is configured to move the flexible outer skin; and
a second movable portion, provided in contact with the outer skin, wherein the second moveable portion is configured to be displaced with respect to the base portion as a result of movement of the flexible outer skin in response to movement of the first movable portion.
2. The robot according to claim 1 , wherein the flexible outer skin has an elastic transformation region between the first movable portion and the base portion, and
the second movable portion contacts the elastic transformation region.
3. The robot according to claim 1 , wherein the flexible outer skin is displaced in accordance with an operation centered on a drive shaft of the first movable portion, and
a deviation between a virtual shaft, fixed relative to a position of the second moveable portion, and the drive shaft increases as a magnitude of movement of the flexible outer skin increases.
4. The robot according to claim 1 , further comprising a third movable portion, wherein
the third moveable portion is connected to the second moveable portion to maintain a relative position between the second moveable portion and the third moveable portion.
5. The robot according to claim 4 , further comprising an annular member connecting the second moveable portion to the third moveable portion.
6. The robot according to claim 5 , wherein the second moveable portion corresponds to a left arm of the robot, and the third moveable portion corresponds to a right arm of the robot.
7. The robot according to claim 5 , wherein the annular member surrounds a periphery of the base portion.
8. The robot according to claim 1 , wherein the flexible outer skin is mounted on the first movable portion, and in a region in the base portion on a side opposite to that of the first movable portion.
9. The robot according to claim 1 , wherein
the base portion comprises:
a cylindrical support portion fixed to an upper portion of the base portion, and
a side plate, wherein a diameter of the side plate is greater than a diameter of the cylindrical support portion,
the second movable portion is supported by an annular member, and
the annular member is configured to fit over the cylindrical support portion, and sit on the side plate.
10. The robot according to claim 9 , wherein the annular member fitted over the support portion is spaced from the support portion by a gap.
11. The robot according to claim 1 , wherein the first movable portion is a head portion having a facial region.
12. The robot according to claim 1 , wherein the second movable portion is linked to a base end of a member configured to attach to the base portion so as to be relatively displaceable, and the second movable portion is displaceable by a motor in the base end.
13. A robot, comprising:
a base portion;
a first movable portion supported by the base portion;
a flexible outer skin provided in such a way as to come into contact with the first movable portion and cover the base portion, wherein movement of the first moveable portion is configured to move the flexible outer skin;
a second movable portion, provided in contact with the outer skin; and
an annular member configured to support the second moveable portion, wherein the annular member is configured to surround a section of the base portion, wherein the annular member is configured to be displaced with respect to the base portion as a result of movement of the flexible outer skin in response to movement of the first movable portion.
14. The robot according to claim 13 , wherein the flexible outer skin has an elastic transformation region between the first movable portion and the base portion, and
the second movable portion contacts the elastic transformation region.
15. The robot according to claim 13 , wherein the flexible outer skin is displaced in accordance with an operation centered on a drive shaft of the first movable portion, and
a deviation between a virtual shaft, extending through a center of the annular member, and the drive shaft increases as a magnitude of movement of the flexible outer skin increases.
16. The robot according to claim 13 , wherein
the base portion comprises:
a cylindrical support portion fixed to an upper portion of the base portion, and
a side plate, wherein a diameter of the side plate is greater than a diameter of the cylindrical support portion, and
the annular member is configured to fit over the cylindrical support portion, and sit on the side plate.
17. The robot according to claim 16 , wherein the annular member fitted over the support portion is spaced from the support portion by a gap.
18. The robot according to claim 13 , wherein the first movable portion is a head portion having a facial region.
19. The robot according to claim 13 , wherein the second movable portion is linked to a base end of a member configured to attach to the base portion so as to be relatively displaceable, and the second movable portion is displaceable by a motor in the base end.
20. A robot, comprising:
a body portion;
a head portion, wherein the head portion is movable relative to the body portion;
a right arm portion;
a left arm portion;
an annular member connecting the right arm portion and the left arm portion, wherein the annular member is between the body portion and the head portion, and the annular member is configured to rest on a section of the body portion; and
a flexible outer skin contacting the body portion, the head portion, the right arm portion and the left arm portion, wherein movement of the head portion relative to the body portion is configured to move the flexible outer skin, and the annular member is configured to be displaced with respect to the base portion by movement of the flexible outer skin in response to movement of the head portion.
