[0002] After the birth of the first milking machine in the early 19th century, various milking machines such as pipeline milking machine, mobile milking machine, centrally mounted milking machine and rotary table milking system have appeared in succession. In 1992, the first commercial fully automatic milking system landed in the Netherlands. As of 2019, about 30000 farms worldwide use automatic milking systems. In recent years, fully automatic milking robots integrating automatic milking systems have gradually entered the field of vision of global dairy industry. Fully automatic milking robots mainly refer to robots that can complete the whole process of milking cows, that is, cows can independently milk, eat and rest according to natural habits, so that cows are more relaxed and healthy during milking. At the same time, through the implementation of online somatic cell detection instrument, cow herd navigator and pasture management system, early warning of cow health problems and milk quality problems can be realized, and unqualified milk can be immediately diverted.

[0003] At present, the existing automatic milking equipment has high cost, and ordinary farmers cannot afford high procurement cost. In addition, during the milking process, the milker is suspended on the cow's teat, which is easy to damage the cow's teat and increase the incidence of cow mastitis.
