DeLaval · Sweden

DeLaval's voluntary milking robot (launched January 2020) — the first milking system to automatically confirm pregnancy, via in-line progesterone sampling (RePro) during milking.

Best for: Dairy herds that want reproduction management (heat + pregnancy detection) built into the milking robot.
Lely · Netherlands

Lely's free-navigating manure robot for solid and semi-closed barn floors — instead of scraping manure ahead of itself it vacuums the slurry into an onboard tank, spraying water at the front for better intake and at the back to leave grip on the floor. Dumping, wireless charging and water refilling happen at one central station; the C2 generation handles barns of up to roughly 120 cows and routes are managed from a mobile app.

Best for: Dairy barns with solid or semi-closed floors (including cross alleys and sorting-gate passages) that want manure removed rather than pushed — cleaner floors and hooves without floor channels or cables.
