  • Publication number: 20180235169
    Abstract: A system for controlling the position of a robot carriage includes a linear carriage track positioned adjacent to a rotary milking platform, a robot carriage positioned on the carriage track such that the robot carriage may move along the carriage track, and a controller. The controller determines a rotational movement of a milking stall of the rotary milking platform, and determines a linear movement of the robot carriage on the carriage track corresponding to the rotational movement of the milking stall of the rotary milking platform. The controller further communicates a signal to a carriage actuator coupled to the robot carriage and the carriage track. The signal causes the carriage actuator to move the robot carriage along the carriage track according to the determined linear movement as the rotary milking platform rotates.

  • Publication number: 20180228116
    Abstract: A system includes a robotic arm and a controller. The controller accesses a first image and a second image generated by a first camera. The controller determines a reference point based at least in part on the first image. The controller determines a position of a teat of the dairy livestock based at least in part on the second image. The controller instructs the robotic arm to grip a milking cup and move it towards the determined position of the teat between the hind legs of the dairy livestock from the rear. The controller then instructs the robotic arm to release the milking cup, to move in an upward direction towards an udder of the dairy livestock, and to move away from the teat.

  • Patent number: 9980458
    Abstract: A system includes a linear carriage track positioned adjacent to a rotary milking platform, a robot carriage positioned on the carriage track such that the robot carriage may move along the carriage track from a first linear position to a second linear position, and a controller. The controller determines a movement of a milking stall of the rotary milking platform from a first rotational position to a second rotational position. The controller further determines the second linear position of the robot carriage on the carriage track corresponding to the movement of the milking stall of the rotary milking platform. The controller also communicates a position signal to a carriage actuator coupled to the robot carriage and the carriage track. The position signal causes the carriage actuator to move the robot carriage along the carriage track from the first linear position to the second linear position in conjunction with the movement of the rotary milking platform.

  • Publication number: 20180103605
    Abstract: A method for applying disinfectant to the teats of a dairy livestock includes determining that a stall of a rotary milking platform housing a dairy livestock is located adjacent to a track that has a carriage carrying a robotic arm. The method continues by communicating a first signal that causes operation of a first actuator such that the carriage moves along the track in relation to the rotary milking platform and independent of any physical coupling between the carriage and the rotary milking platform and in a direction corresponding to a direction of rotation of the rotary milking platform. The method concludes by communicating one or more additional signals that causes operation of one or more actuators of the robotic arm such that at least a portion of the robotic arm extends between the hind legs of a dairy livestock.
