A system includes a controller and a robotic arm. The controller accesses an image signal of an udder of a dairy livestock, and determines a spray position by processing the accessed image signal to determine a tangent at the rear of the udder and a tangent at the bottom of the udder. The spray position is a position relative to the intersection of the two tangents. A robotic arm communicatively coupled to the controller positions a spray tool at the spray position.

A method for applying disinfectant to the teats of a dairy livestock, comprises moving a carriage along a track. The carriage carries a robotic arm and the track is adjacent to a stall of a rotary milking platform housing a dairy livestock. The robotic arm comprises a first member pivotally attached to the carriage, a second member pivotally attached to the first member, and a spray tool member pivotally attached to the second member. The method continues by extending the robotic arm between the hind legs of the dairy livestock while the rotary milking platform rotates such that a spray tool of the spray tool member is located at a spray position from which the spray tool may discharge disinfectant to the teats of the dairy livestock.

A system for operating a robotic arm, comprises a controller and a robotic arm. The controller receives an indication that a stall of a rotary milking platform in which a dairy livestock is located has moved into an area adjacent a robotic arm that is detached from the rotary milking platform. The controller also determines whether a milking cluster is attached to the dairy livestock. The robotic arm is communicatively coupled to the controller and extends between the legs of the dairy livestock if the controller determines that the milking cluster is not attached to the dairy livestock. The robotic arm does not extend between the legs of the dairy livestock if the controller determines that the milking cluster is attached to the dairy livestock.

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.

A system includes a camera, a controller and a robotic arm. The camera generates an image of an udder of a dairy livestock. The controller determines a position of the udder of the dairy livestock based at least in part upon the image. The controller further determines a spray position based at least in part upon the determined position of the udder of the dairy livestock. Determining the spray position includes processing the accessed image to determine a tangent at the rear of the udder and a tangent at the bottom of the udder. The spray position is a position relative to the intersection of the two tangents. The robotic arm is communicatively coupled to the controller and positions a spray tool at the spray position.

A method for operating a robotic arm, comprises determining a speed of rotation of a rotary milking platform, the rotary milking platform having a stall for a dairy livestock. The method continues by moving a carriage along a track positioned adjacent to the rotary milking platform at a rate that is based at least in part upon the determined speed of rotation of the rotary milking platform, wherein the carriage moves independently of the rotary milking platform and in a direction corresponding to a direction of rotation of the rotary milking platform. The method continues by extending a robotic arm that is coupled to the carriage between the legs of the dairy livestock, wherein the robotic arm remains extended between the legs of the dairy livestock for a period of time as the stall rotates adjacent to the robotic arm. The method concludes by retracting the robotic arm from between the legs of the dairy livestock as the stall rotates adjacent to the robotic arm.

In certain embodiments, a system for applying disinfectant to the teats of a dairy livestock includes a carriage mounted on a track, the carriage operable to translate laterally along the track. The system further includes a robotic arm including a first member pivotally attached to the carriage such that the first member may rotate about a point of attachment to the carriage, a second member pivotally attached to the first member such that the second member may rotate about a point of attachment to the first member, and a spray tool member pivotally attached to the second member such that the spray tool member may rotate about a point of attachment to the second member. The robotic arm further includes a spray tool attached to the spray tool member. The system further includes a controller operable to cause at least a portion of the robotic arm to extend between the hind legs of a dairy livestock such that the spray tool is located at a spray position from which the spray tool may discharge an amount of disinfectant to the teats of the dairy livestock.

A spray tool coupled to a robotic arm that extends between the legs of dairy livestock, comprises a linear member and a plurality of spray nozzles. The linear member rotates about an axis that is perpendicular to the robotic arm, and has a perimeter that lies within an outer perimeter of the robotic arm when the robotic arm extends between the legs of a dairy livestock. The plurality of spray nozzles are coupled to the linear member.
