Aramis II vs Juno
Two robotic barn machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Rail-guided all-in-one feeding robot from Tyrolean specialist Hetwin — weighs, cuts, mixes, doses and pushes feed around the clock from an overhead rail, with two horizontal mixing augers producing a homogeneous ration from batches as small as 50 kg. Aimed at medium herds of roughly 50–150 animals; sold and serviced in Switzerland via Harvestore.
Best for: Medium dairy and fattening barns (≈50–150 animals) wanting fully automatic group-specific fresh feeding without a mixer wagon — overhead rail keeps the feed alley clear.Lely's battery-electric automatic feed pusher — follows pre-installed floor strips with ultrasound distance sensing to push feed to the fence up to 48 times a day, returning to its charging station between runs. Current line is Juno / Juno Flex; the lidar-navigating Juno Max for 800+ cow farms was unveiled September 2024 with commercial launch expected 2027. Swiss sales and service via Lely Center Härkingen.
Best for: Any dairy or beef barn with a feed alley — frequent pushing raises intake day and night for a modest, low-maintenance robot.| Aramis II Verified 2026-07-16 | Juno Verified 2026-07-16 | |
