Automated Milking Robot Designed and Developed

During a routine visit to a well known manufacturer of automated milking systems, ERIKS were asked to offer a DC motor to replace an existing air motor.

But ERIKS didn’t just supply a motor...


The existing air motor was used to drive two contra-rotating shafts via a gear train. Brushes are attached to the shafts and the whole mechanism is mounted on the arm of an automatic milking machine. Prior to being milked the cows teats are washed and disinfected to prevent contamination. It may sound like a simple, run of the mill application but this is far from the case as ERIKS discovered. To automate the process safely and efficiently, there are many aspects to consider.


By pooling the customers and ERIKS knowledge, the resultant machine operates as follows:

The machine recognises the individual animal by sensing an electronic ear tag. It then dispenses the correct mix and amount of feed into the feeding bowl to which the cow advances.
Automatic gates then close to keep the cow in place and a laser scanner (or camera) scans the udders and teats so the automatic cleaning system can operate in the correct area.
The milking couplers are then attached to the teats and milking commences. In a separate operation, the milk is tested to ensure it is not contaminated and then pumped to a central tank. Once the feed is finished the couplers disengage, the gates open and the cow walks free.
Cows can yield milk three to five times a day but if the cow tries to get into the machine again too soon after a milking cycle, the machine recognises the cow cannot give milk again so soon (due to the ear tag scanner) and the gates will not open.
This method of milking is substantially increasing the milk yield for the dairies already using the technology and the potential is huge.
