Lely Astronaut A5

Last updated: April 2026

The Lely Astronaut A5 is a fully automatic robotic milking system that allows dairy cows to choose when they want to be milked, improving animal welfare and increasing milk production by up to 12%. The system identifies each cow individually, attaches the milking cups automatically using 3D camera technology, and monitors milk quality in real time by measuring color, conductivity, and temperature. Each A5 unit can handle 60-70 cows with an average of 2.5-3 milkings per day per cow, significantly reducing the daily labor burden on dairy farmers. The automatic cleaning cycle between each cow ensures hygiene standards exceed manual milking, reducing mastitis rates and improving overall herd health. With over 40,000 units installed worldwide, the Astronaut A5 is the most widely deployed robotic milking system in the dairy industry.
