Fullwood (formerly Fullwood JOZ) · United Kingdom

The independent alternative to the big-three milking robots — Fullwood (milking robots since 1996, rebranded from Fullwood JOZ) has built the M²erlin since 2014 around an open box, natural walk-through entrance/exit and a quiet electric robot arm. Ten years of incremental upgrades include TDS2 laser udder recognition (2020), FullCount real-time somatic cell counting (2021) and the FULLSENSE software platform (2023). Hundreds of farms run it worldwide; the Meridian variant does robotic batch milking in groups.

Best for: Dairy farms wanting a low-stress open-box robot with per-quarter monitoring from a long-established independent maker, or batch-milking herds (Meridian) that keep parlour-style routines with robot labour.
Lely · Netherlands

Robotic milking system — cows milk on their own schedule around the clock; the A5 Next (June 2025) adds a new OS with over-the-air updates, laser+camera teat detection and an automatic milk filter.

Best for: Dairy herds of 50–120 cows seeking to cut milking labour and lift yield per cow.
