Sprout

Muddy Machines · United Kingdom

UK-built selective-harvesting robot for green asparagus — self-navigates rows, uses computer vision to identify and measure ripe spears, then cuts and conveys them into onboard trays, letting one supervisor oversee up to ten units at once. Field-trialled since 2021 (Cobrey Farms, Herefordshire) and deployed on a small number of UK asparagus farms through 2024–25. Muddy Machines Ltd announced it was winding down in May 2025 after failing to close a further funding round, and Companies House lists the company as in liquidation as of mid-2026 — the machine is no longer sold, manufactured, or supported.

At a glance

Best for

Historical reference only — was best suited to large UK asparagus growers facing the crop's steep seasonal labour bill (traditionally 400–850 pickers for a 2.5–3 month harvest window).

Avoid if

You are trying to buy, lease, or get support for a Sprout unit today — the manufacturer has ceased trading and is in formal liquidation; there is no dealer, parts, or software support channel left.

Not suitable for

Any current purchase decision; any crop other than asparagus (broccoli/courgette tooling was announced but never reached commercial deployment before the company wound down).

EU Machinery RegulationUK-only deployment found; would fall under Regulation (EU) 2023/1230 autonomous-machine provisions if ever placed on the EU market, but the manufacturer is now defunct
AI Act relevanceWould likely be limited-risk (onboard computer vision for crop identification); moot given liquidation
CAP subsidyNot applicable — UK-based, outside EU CAP, and manufacturer defunct

Agrobot (Soluciones Robóticas Agrícolas S.L.) · Spain

Spanish robotic strawberry harvester from Huelva with up to 24 independent picking arms that grip and cut the stem so fruit is never touched, guided by colour/infrared depth sensors and LiDAR. A long-running pioneer (field work in Huelva and California, early Driscoll's trials) — but Agrobot itself still labels the E-Series pre-commercial and 'not for sale, project on development' as of 2026, with thin recent public evidence of commercial deployments.
