CLAWS vs Robovator
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.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).| CLAWS Verified 2026-07-17 | Robovator Verified 2026-07-18 | |

| Specifications | ||
| Power source | 100% electric — battery + solar; battery alone runs roughly half a day, solar panels extend to a full day | Tractor-mounted implement, PTO-driven hydraulics (~1 hp per row) |
| Required tractor power | Is the vehicle (lightweight autonomous platform, no tractor needed) | 3-point-hitch mounted; requires tractor PTO shaft speed of at least 420 rpm (hydraulic pressure and lamps cut out below ~360 rpm) |
| Dimensions | ~2 m working width; other dimensions not disclosed | Configurable 5 to 31 rows; row spacing adjustable 25–75 cm (9–30 in); US-market spec sheet lists 6–12 lines per bed with 60–84 in bed spacing |
| Weight | Not disclosed | 700 kg (1,500 lb) base weight |
| Min farm size | Not disclosed | Not disclosed |
| Productivity | ~1.5 ha per 8 h day demonstrated; ~4 ha/day targeted for the commercial fully autonomous machine, weed burden depending | Roughly 1.5–2 acres/hour depending on soil and plant conditions (per Pacific Ag Rentals, US distributor); manufacturer-stated field speed 2–8 km/h (1.2–5 mph) |
| Max speed | Not disclosed | 2–8 km/h (1.2–5 mph) |
| Sensors | 8 onboard cameras (stereo imaging) · AI per-plant identification · satellite navigation · FIELD digital-twin scouting software | One plant-detection camera per row for image-based crop location, functions in low light; automatic self-centring side-shift (±40 cm range, engages after ~1 m of travel) |
| Price & model | ||
| Price (EUR) | Not disclosed | Not disclosed |
| Native price | Not disclosed | Not disclosed |
| Business model | Weeding as a service, charged per hectare — positioned at parity with tractor-based weeding and below manual weeding cost | Buy — tractor-mounted implement sold direct from F. Poulsen Engineering (Denmark) and via distributors, including Agri Evolution (Netherlands, EU) and Pacific Ag Rentals (Salinas, California, western US) |
| Ongoing cost | Service-model pricing per hectare; no published machine list price | Wear parts (weeding knives/blades, camera lens care), hydraulic fluid and PTO shaft maintenance; no software subscription published |
| Key outcome | ||
| Best verified result | Herbicide use Chemical-free concentrated-light weeding, zero-till; controls ALS-resistant weeds (Niab-tested, vendor-reported) · vendor | Intra-row weed removal vs. a standard cultivator +18 to +41 percentage points · independent |
| EU context | ||
| CE marking | Not verified — pre-series Beta Pioneer machine, UK-focused rollout | 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) |
| Machinery Regulation | Post-Brexit UK machine; EU conformity route not published | Tractor-mounted implement falling under the EU Machinery Regulation (EU) 2023/1230; the tractor operator remains in control at all times |
| CAP subsidy | Chemical-free zero-till weeding aligns with CAP eco-scheme goals, but no EU sales channel is evidenced yet | Herbicide-free/reduced mechanical in-row weeding supports CAP eco-scheme and organic-conversion measures |
