Abstract

An apparatus comprises a milking box having a stall to accommodate a dairy livestock and a robotic attacher. The robotic attacher comprises a main arm that is suspended vertically from a rail of the milking box, and a supplemental arm that is coupled to and extends horizontally from the main arm along a longitudinal axis. The supplemental arm comprises a pivot assembly that pivots a gripping portion around a vertical axis that is substantially parallel to the main arm of the robotic attacher, in a direction transverse to the longitudinal direction of the supplemental arm.

First claim

What is claimed is:

1. An apparatus, comprising:
a milking box having a stall to accommodate a dairy livestock;
a robotic attacher comprising a main arm that is suspended vertically from a rail of the milking box, and a supplemental arm that is coupled to and extends horizontally from the main arm along a longitudinal axis, wherein the supplemental arm comprises a pivot assembly that pivots a gripping portion around a vertical axis that is substantially parallel to the main arm of the robotic attacher, in a direction transverse to the longitudinal direction of the supplemental arm, and between at least a maximum-left position, a maximum-right position, and a centered position;
the pivot assembly comprising:
a first actuator operable to extend and retract a first cable coupled to a left side of the gripping portion in order to pivot the gripping portion; and
a second actuator operable to extend and retract a second cable coupled to a right side of the gripping portion in order to pivot the gripping portion.

2. The apparatus of claim 1 , further comprising a third actuator operable to pivot the gripping portion to the centered position by pushing a plate against the first and second actuators such that the first and second actuators evenly retract the first and second cables.

3. The apparatus of claim 1 , wherein the supplemental arm further comprises a rotating assembly that rotates the gripping portion about the longitudinal axis of the supplemental arm between at least an upright position and an upside down position.

4. The apparatus of claim 1 , wherein the supplemental arm further comprises a gripper comprising claw arms operable to open and close.

5. An apparatus, comprising:
a milking box having a stall to accommodate a dairy livestock;
a robotic attacher comprising a main arm that is suspended vertically from a rail of the milking box, and a supplemental arm that is coupled to and extends horizontally from the main arm along a longitudinal axis, wherein the supplemental arm comprises a pivot assembly that pivots a gripping portion around a vertical axis that is substantially parallel to the main arm of the robotic attacher, in a direction transverse to the longitudinal direction of the supplemental arm;
the pivot assembly comprising:
a first actuator operable to extend and retract a first cable coupled to a left side of the gripping portion in order to pivot the gripping portion; and
the second actuator operable to extend and retract a second cable coupled to a right side of the gripping portion in order to pivot the gripping portion.

6. The apparatus of claim 5 , further comprising a third actuator operable to pivot the gripping portion to a centered position by pushing a plate against the first and second actuators such that the first and second actuators evenly retract the first and second cables.

7. The apparatus of claim 5 , wherein the transverse direction includes at least a left position, a center position, and a right position.

8. The apparatus of claim 5 , wherein the supplemental arm further comprises a rotating assembly that rotates the gripping portion about the longitudinal axis of the supplemental arm between at least an upright position and an upside down position.

9. The apparatus of claim 5 , wherein the supplemental arm further comprises a gripper comprising claw arms operable to open and close.
