Abstract: An automatic teat treatment method and apparatus uses a control system and an associated robot apparatus with an arm that carries a treatment apparatus, to establish a treatment operation start time and establish the presence of an animal at a treatment location, and then (i) initiate detection of a spatial teat position of a first teat, (ii) register the spatial position, (iii) derive a dedicated teat-treating action, (iv) carry out the teat-treating action, and (v) successively repeat the initiating, registering, deriving, and treating steps once in respect of each teat until all teats are treated, where, when after the start time, a predefined point in time is passed before any of the preceding steps is completed, the method is interrupted and a default treating action for treating all remaining untreated teats is derived and carried out by the treatment apparatus and thereafter the robot arm is retracted.
