CLAWS 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.
Concentrated Light Autonomous Weeding and Scouting (CLAWS) robot from UK startup Earth Rover — its patented Lightweeder destroys the meristem of individual weeds with a short pulse of concentrated (non-laser) light, chemical-free and zero-till, on a 100% battery + solar platform with 8 onboard cameras that double as a crop-scouting system. Order book opened Q3 2025; deliveries scheduled from Q1 2026 under a weeding-as-a-service model.
Best for: Organic and chemical-free vegetable and row-crop growers (UK first) who want herbicide-free, zero-till weed control plus per-plant scouting data, paid per hectare rather than as capex.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.| CLAWS Verified 2026-07-17 | Field Friend (Feldfreund) Verified 2026-07-17 | |

| CE marking | Not verified — pre-series Beta Pioneer machine, UK-focused rollout | German-built machine operating commercially in Germany; CE status not independently verified |
| Machinery Regulation | Post-Brexit UK machine; EU conformity route not published | EU-built; conformity route under the EU machinery regime not published |
| CAP subsidy | Chemical-free zero-till weeding aligns with CAP eco-scheme goals, but no EU sales channel is evidenced yet | Herbicide-free mechanical weeding supports CAP eco-scheme and organic goals |
