Abstract

A system for operating a robotic arm comprises a carriage and a robotic arm. The carriage is mounted on a track adjacent to a rotary milking platform having a substantially circular perimeter and a stall for a dairy livestock. The carriage moves along a substantially straight portion of the track tangent to and outside the perimeter of the rotary milking platform at a rate based at least in part upon a speed of rotation of the rotary milking platform. The carriage moves in a direction corresponding to the direction of rotation of the rotary milking platform and such movement of the carriage is independent of any physical coupling between the carriage and the rotary milking platform. The robotic arm extends between the legs of the dairy livestock.

First claim

What is claimed is:

1. A system for operating a robotic arm, comprising:
a carriage mounted on a track positioned adjacent to a rotary milking platform having a substantially circular perimeter and a stall for a dairy livestock, the carriage operable to move along a substantially straight portion of the track tangent to and outside the perimeter of the rotary milking platform at a rate based at least in part upon a speed of rotation of the rotary milking platform, wherein the carriage moves in a direction corresponding to the direction of rotation of the rotary milking platform and such movement of the carriage is independent of any physical coupling between the carriage and the rotary milking platform; and
a robotic arm coupled to the carriage and operable to extend between the legs of the dairy livestock.

2. The system of claim 1 , further comprising a controller operable to determine the rate for the carriage to move along the substantially straight portion of the track.

3. The system of claim 1 , wherein the carriage moves along the track in response to a signal indicating the speed of rotation of the rotary milking platform.

4. The system of claim 3 , further comprising a rotary encoder attached to the rotary milking platform and operable to generate the signal.

5. The system of claim 1 , further comprising a drive mechanism that moves the carriage along the track at the rate based at least in part upon the speed of rotation of the rotary milking platform.

6. A system for operating a robotic arm, comprising:
a carriage mounted on a track adjacent to a rotary milking platform having at least one stall for a dairy livestock, wherein the rotary milking platform has a substantially circular perimeter;
a drive mechanism coupled to the carriage and operable to move the carriage along the track tangent to and outside the perimeter of the rotary milking platform and independently of any drive mechanism associated with the rotary milking platform; and
a robotic arm coupled to the carriage and operable to extend between the legs of the dairy livestock, wherein the robotic arm remains uncoupled from the rotary milking platform.

7. The system of claim 6 , wherein the carriage is operable to move along a substantially straight portion of the track.

8. The system of claim 6 , wherein the drive mechanism is operable to move the carriage along the track in response to a signal indicating a speed of rotation of the rotary milking platform.

9. The system of claim 8 , further comprising a rotary encoder attached to the rotary milking platform and operable to generate the signal.

10. The system of claim 8 , wherein the drive mechanism moves the carriage along the track at a rate based at least in part upon the speed of rotation of the rotary milking platform.

11. The system of claim 10 , further comprising a controller operable to determine the rate for the drive mechanism to move the carriage along the track.

12. A method for operating a robotic arm, comprising:
moving a carriage along a track adjacent to a rotary milking platform having a substantially circular perimeter and a stall for a dairy livestock, wherein the carriage moves along a substantially straight portion of the track tangent to and outside the perimeter of the rotary milking platform at a rate based at least in part upon a speed of rotation of the rotary milking platform; and
extending a robotic arm coupled to the carriage between the legs of the dairy livestock.

13. The method of claim 12 , further comprising discharging a substance to at least some of the teats of the dairy livestock when the robotic arm is extended between the legs of the dairy livestock.

14. The method of claim 12 , wherein moving the carriage comprises moving the carriage along the track in response to a signal indicating the speed of rotation of the rotary milking platform.

15. The method of claim 12 , further comprising using a rotary encoder to determine the speed of rotation of the rotary milking platform.
