Abstract
This robot comprises: a drive device which has formed therein a hollow part that extends in a direction along the axis of rotation; and an optical cable which is disposed so as to pass through the interior of the hollow part. The robot is equipped with a first supporting member and a second supporting member that support the optical cable. The first supporting member is fixed to a member that remains still during driving of the drive device. The second supporting member is fixed to a member that rotates during driving of the drive device. The first supporting member and the second supporting member are formed so as to support the optical cable on the axis of rotation.
Claims9
A robot comprising:
- a drive device configured to rotate a second constituent member of the robot around a rotation axis with respect to a first constituent member of the robot;
- a member including a hollow portion extending in a direction along the rotation axis;
- an optical cable arranged so as to pass through an inside of the hollow portion;
- a first support member arranged on one side in an axial direction of the hollow portion and configured to support the optical cable;
- and
- a second support member arranged on a side opposite to the one side in the axial direction of the hollow portion and configured to support the optical cable, wherein
- the first support member is fixed to a member that is stationary when the drive device is driven,
- the second support member is fixed to a member that rotates when the drive device is driven,
- the first support member and the second support member are configured to support the optical cable substantially on the rotation axis, and
- when the drive device is driven, the second support member rotates with respect to the first support member so that the optical cable is twisted between the first support member and the second support member.
A drive device configured to relatively rotate two members different from each other around a rotation axis, and including a hollow portion extending in a direction along the rotation axis, the drive device comprising:
- an electric motor configured to generate a rotational force;
- a first support member arranged on one side in an axial direction of the hollow portion and configured to support an optical cable so as to pass through an inside of the hollow portion, and
- a second support member arranged on a side opposite to the one side in the axial direction of the hollow portion and configured to support the optical cable, wherein
- the first support member is fixed to a constituent member of the drive device that is stationary when the electric motor is driven,
- the second support member is fixed to a constituent member of the drive device that rotates when the electric motor is driven,
- the first support member and the second support member are configured to support the optical cable substantially on the rotation axis, and
- when the electric motor is driven, the second support member rotates with respect to the first support member so that the optical cable is twisted between the first support member and the second support member.
