Lely Astronaut A5 Milking Robot

The Lely Astronaut A5 is the industry-leading automatic milking system that allows dairy cows to choose when they are milked, 24 hours a day. Cows voluntarily enter the milking box, and the robot uses cameras and sensors to locate teats, attach cups, milk the cow, and monitor milk quality — all without human intervention.

The A5’s I-flow concept provides a natural, calm cow traffic pattern that reduces stress and increases voluntary visit frequency. Each milking session collects detailed data on milk yield, quality, and cow health indicators including mastitis detection, enabling proactive herd management and early disease intervention.
