The use of robots for milking cows contributes to the emergence of an almost new technology, the main essence of which is the self-service of the animal. She leaves the cow the right to freedom of choice of the term and frequency of visits to the milking parlor. [2]

However, studies have shown that not all animals get used to milking by a robot quickly enough: 188 cows of the studied livestock went to milking 896 times, while 41 attempts were unsuccessful (4.6%), 2 cows never milked during the day. There are cows in the herd who do not want to go to milking on their own. The number of visits to the milking robot by one cow varied from 2 times a day (3.7%) to 8 times (3.2%). Most cows had 4-5 attempts. It is especially important to note that the maximum duration of milking one fraction out of four varied in different robots from 8 min 14 sec to 14 min 37 sec. The minimum time is from 0 to 6 min 45 sec. the number of such "zero" shares varied from 10.9% (1 robot) to 59% (4 robots). Therefore, in order to increase the efficiency of the use of robot milkers, it is necessary to carry out work on the assessment and selection of animals by temperament and by the uniformity of udder development.
