Robovator vs Field Friend (Feldfreund)
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Tractor-mounted, vision-guided intra-row hoeing implement from Danish manufacturer F. Poulsen Engineering — a camera above each row spots individual plants and hydraulically swings weeding knives out and back around them, removing weeds between plants without touching the crop. Commercially sold since the early 2010s and independently trialled in US vegetable production; configurable from 5 to 31 rows and adjustable to 25–75 cm row spacing.
Best for: Vegetable, sugar-beet and row-crop growers with a suitable PTO tractor who want camera-guided mechanical in-row weeding to cut herbicide use and hand-weeding labour, across a wide range of farm scales (5- to 31-row configurations).Modular AI mini field robot from Zauberzeug (Havixbeck, Münsterland) — a ~100 kg tracked platform under 1 m³ that uses onboard camera AI (the "Zauberzeug Robot Brain" edge-compute unit) to distinguish crops from weeds and mechanically remove them, including deep-rooted weeds. Offered both as a pay-per-hour weeding service (no machine purchase) and as a development platform; trade press reported roughly €20,000 for the machine with tools up to ~€5,000 extra. Winner of the Münsterland Innovation Award 2023/24.
Best for: Small-scale German vegetable and row-crop growers, market gardens and research users who want camera-guided mechanical in-row weeding without a big capex — pay per hour of weeding done.| Robovator Verified 2026-07-18 | Field Friend (Feldfreund) Verified 2026-07-17 | |

| EU context | ||
| CE marking | No CE-marking statement found in the manufacturer's public materials, so compliance is listed as not confirmed — although CE marking is legally required to place machinery on the EU market and F. Poulsen actively sells within the EU (Denmark, and via Netherlands distributor Agri Evolution) | German-built machine operating commercially in Germany; CE status not independently verified |
| Machinery Regulation | Tractor-mounted implement falling under the EU Machinery Regulation (EU) 2023/1230; the tractor operator remains in control at all times | EU-built; conformity route under the EU machinery regime not published |
| CAP subsidy | Herbicide-free/reduced mechanical in-row weeding supports CAP eco-scheme and organic-conversion measures | Herbicide-free mechanical weeding supports CAP eco-scheme and organic goals |
