The embodiments are directed to a hand-held applicator (126) for cleaning a teat of a milk-producing animal. The hand-held applicator comprises: a first housing having housing section (209) including a first end through which a disinfectant delivery line (140) extends or an electrical line (198) extends; and second housing (205) coupled to the housing section and having a sealed gear chamber (216) for supporting gears (186A, 186B and 186C) and bearings. The second housing comprises a first portion (213) and a second portion (215) configured to be removably affixed in abutting contact to the first portion. The second housing has an external delivery port (579) centered between a pair of side-by-side gears. The applicator comprises a switch (232) positioned on the underside of the housing section. The second portion may include a motor mount (680) for coupling a motor (238) in the housing section.

In certain embodiments, a system includes a front wall, a rear wall positioned substantially parallel to the front wall, and first and second side walls each extending between the front wall and the rear wall. The first side wall includes a gate, and the second side wall is spaced apart from the first side wall such that the front wall, the rear wall, the first side wall, and the second side wall define a milking box stall of a size sufficient to accommodate a dairy livestock. The system includes an equipment portion located adjacent to the rear wall. The equipment portion houses a robotic attacher configured to extend between the rear legs of a dairy livestock located within the milking box stall in order to attach milking equipment to the dairy livestock.

A system for operating a robotic arm comprises a carriage, a controller communicatively coupled to the carriage and a robotic arm coupled to the carriage. The carriage is mounted on a track adjacent to a rotary milking platform having a stall for a dairy livestock. The carriage moves along the track in a direction corresponding to a direction of rotation of the rotary milking platform. The controller determines a rate for the carriage to move along the track based at least in part upon a speed of rotation of the rotary milking platform. The robotic arm extends between the legs of the dairy livestock.

Sensor system with a sensor device having a through-flow cell for liquid, a detector device for measuring a property of the liquid in the through-flow cell and for generating an associated detector signal, a sensor control for analyzing the detector signal, wherein the sensor control detects a liquid transition between two different liquids in the through-flow cell when a change (per unit time) in the detector signal is greater than a threshold value. In the case of such a liquid transition detection, the sensor control generates an alarm signal. Liquid transition detection is carried out by optical, temperature and/or conductivity sensors.

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 comprises positioning a robotic attacher under a dairy livestock located in a milking stall, wherein the robotic attacher comprises a nozzle. The method continues by rotating the robotic attacher such that the nozzle is positioned generally on the top of the robotic attacher and performing a spraying operation using the nozzle. The method concludes by retracting the robotic attacher from under the dairy livestock.
